PipeServer Component

Properties   Methods   Events   Config Settings   Errors  

The PipeServer component is a lightweight server component based on an asynchronous, event-driven architecture. It is designed to balance the load between connections for a fast, powerful server.

Syntax

nsoftware.IPWorksIPC.Pipeserver

Remarks

PipeServer is the server complement of PipeClient (which is used to create client applications). They share a common design philosophy and interface. PipeServer is as easy to use as PipeClient.

The client connections are identified by a ConnectionId, an id generated by the component to identify each connection. This id is unique to each connection. PipeServer's events also have ConnectionId as a parameter to identify the connection to which they are related.

Our main goal in designing PipeServer was to make it easy to use without sacrificing performance. The component has a minimum of properties, and events: Connected, DataIn, Disconnected, ReadyToSend, and Error.

PipeServer can start to listen on a pipe by setting PipeName and then setting Listening to True. When a client connects the Connected event fires, a ConnectionId is assigned, and communication can start. From this point on, the operation is very similar to PipeClient. Data is sent by assigning the data string to the DataToSend field.

Connections Property (PipeServer Component)

A collection of currently connected clients.

Syntax

public PipeConnectionMap Connections { get; }
Public ReadOnly Property Connections As PipeConnectionMap

Remarks

This property contains a collection of currently connected clients. All of the connections may be managed using this property. Each connection is described by the different fields of the PipeConnection type.

This collection is a hashtable type of collection, in which the Connection Id string is used as the key to the desired connection. The Connected event fires when a client connects and provides the Connection Id (key) that identifies the client.

Example (Broadcasting Data) foreach (Connection c in pipeserver1.Connections.Values) { c.DataToSend = "Broadcast Data"; }

This property is read-only.

Please refer to the PipeConnection type for a complete list of fields.

DefaultEOL Property (PipeServer Component)

This property includes a default end-of-line (EOL) value to be used by incoming connections.

Syntax

public string DefaultEOL { get; set; }
public byte[] DefaultEOLB { get; set; }
Public Property DefaultEOL As String
Public Property DefaultEOLB As Byte()

Default Value

""

Remarks

This property contains a default end-of-line (EOL) value to be used by incoming connections. Once the component accepts and establishes an inbound connection, it will set that connection's EOL to the value in this property. By default, this value is empty (""), meaning that data will be fired as it is received.

DefaultMaxLineLength Property (PipeServer Component)

The property includes the default maximum line length value for inbound connections.

Syntax

public int DefaultMaxLineLength { get; set; }
Public Property DefaultMaxLineLength As Integer

Default Value

2048

Remarks

This property controls the default size of an internal buffer that holds received data while waiting for an end-of-line (EOL) string.

The minimum value for this property is 256 bytes. The default value is 2048 bytes.

DefaultSingleLineMode Property (PipeServer Component)

This property tells the component whether or not to treat new connections as line oriented.

Syntax

public bool DefaultSingleLineMode { get; set; }
Public Property DefaultSingleLineMode As Boolean

Default Value

False

Remarks

This property instructs the component whether or not to treat newly established connections as line-oriented protocols. If this value is True, newly accepted connections will read the incoming data stream as lines separated by a carriage return line feed (CRLF), carriage return (CR), or line feed (LF) and will ignore the end of lines (EOLs).

DefaultTimeout Property (PipeServer Component)

This property includes an initial timeout value to be used by incoming connections.

Syntax

public int DefaultTimeout { get; set; }
Public Property DefaultTimeout As Integer

Default Value

0

Remarks

This property is used by the component to set the operational timeout value of all inbound connections once they are established.

This property defines the timeout when sending data. When SSLEnabled is False, a value of 0 means data will be sent asynchronously, and a positive value means data is sent synchronously.

When SSLEnabled is True, all data are sent synchronously regardless of the Timeout value.

Listening Property (PipeServer Component)

If True, the component accepts incoming connections.

Syntax

public bool Listening { get; set; }
Public Property Listening As Boolean

Default Value

False

Remarks

Use this property to make the component 'listen' (accept connections) on the pipe specified by PipeName. Setting this property to False will make the component stop listening. Please note that this does not close any existing connections.

Note: Use the StartListening and StopListening methods to control whether the component is listening.

This property is not available at design time.

PipeName Property (PipeServer Component)

The name of the pipe.

Syntax

public string PipeName { get; set; }
Public Property PipeName As String

Default Value

""

Remarks

This property specifies the name of the pipe on which to accept connections. Clients must use this name when establishing a connection to PipeServer.

Config Method (PipeServer Component)

Sets or retrieves a configuration setting.

Syntax

public string Config(string configurationString);

Async Version
public async Task<string> Config(string configurationString);
public async Task<string> Config(string configurationString, CancellationToken cancellationToken);
Public Function Config(ByVal ConfigurationString As String) As String

Async Version
Public Function Config(ByVal ConfigurationString As String) As Task(Of String)
Public Function Config(ByVal ConfigurationString As String, cancellationToken As CancellationToken) As Task(Of String)

Remarks

Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

Disconnect Method (PipeServer Component)

This method disconnects the specified client.

Syntax

public void Disconnect(string connectionId);

Async Version
public async Task Disconnect(string connectionId);
public async Task Disconnect(string connectionId, CancellationToken cancellationToken);
Public Sub Disconnect(ByVal ConnectionId As String)

Async Version
Public Sub Disconnect(ByVal ConnectionId As String) As Task
Public Sub Disconnect(ByVal ConnectionId As String, cancellationToken As CancellationToken) As Task

Remarks

Calling this method will disconnect the client specified by the ConnectionId parameter.

DoEvents Method (PipeServer Component)

Processes events from the internal message queue.

Syntax

public void DoEvents();

Async Version
public async Task DoEvents();
public async Task DoEvents(CancellationToken cancellationToken);
Public Sub DoEvents()

Async Version
Public Sub DoEvents() As Task
Public Sub DoEvents(cancellationToken As CancellationToken) As Task

Remarks

When DoEvents is called, the component processes any available events. If no events are available, it waits for a preset period of time, and then returns.

Interrupt Method (PipeServer Component)

This method interrupts a synchronous send to the remote host.

Syntax

public void Interrupt(string connectionId);

Async Version
public async Task Interrupt(string connectionId);
public async Task Interrupt(string connectionId, CancellationToken cancellationToken);
Public Sub Interrupt(ByVal ConnectionId As String)

Async Version
Public Sub Interrupt(ByVal ConnectionId As String) As Task
Public Sub Interrupt(ByVal ConnectionId As String, cancellationToken As CancellationToken) As Task

Remarks

This property is called using the Connection Id if you wish to interrupt a connection and stop a file from uploading without disconnecting the client connected to the component. If you use SendFile to upload a file, the component will run synchronously on that Connection Id until it is completed.

Send Method (PipeServer Component)

This method sends binary data to the specified client.

Syntax

public void Send(string connectionId, byte[] text);

Async Version
public async Task Send(string connectionId, byte[] text);
public async Task Send(string connectionId, byte[] text, CancellationToken cancellationToken);
Public Sub Send(ByVal ConnectionId As String, ByVal Text As String)

Async Version
Public Sub Send(ByVal ConnectionId As String, ByVal Text As String) As Task
Public Sub Send(ByVal ConnectionId As String, ByVal Text As String, cancellationToken As CancellationToken) As Task

Remarks

This method sends binary data to the client identified by ConnectionId. To send text, use the SendText method instead.

When Timeout is set to 0 and SSLEnabled is set to False, the component will behave asynchronously. If you are sending data to the remote host faster than it can process it, or faster than the network's bandwidth allows, the outgoing queue might fill up. When this happens, the operation fails with exception 10035: "[10035] Operation would block" (WSAEWOULDBLOCK). You can check this error, and then try to send the data again. . The BytesSent property shows how many bytes were sent (if any). If 0 bytes were sent, then you can wait for the ReadyToSend event before attempting to send data again.

Note: The ReadyToSend event is not fired when part of the data is sent successfully.

When SSLEnabled is True or Timeout is set to a positive value, the component behaves synchronously.

SendFile Method (PipeServer Component)

This method sends the file to the remote host.

Syntax

public void SendFile(string connectionId, string fileName);

Async Version
public async Task SendFile(string connectionId, string fileName);
public async Task SendFile(string connectionId, string fileName, CancellationToken cancellationToken);
Public Sub SendFile(ByVal ConnectionId As String, ByVal FileName As String)

Async Version
Public Sub SendFile(ByVal ConnectionId As String, ByVal FileName As String) As Task
Public Sub SendFile(ByVal ConnectionId As String, ByVal FileName As String, cancellationToken As CancellationToken) As Task

Remarks

This method sends the file to the client specified by the ConnectionId.

Note: This method operate synchronously. DefaultTimeout or Timeout must be set to a positive value before calling this method.

SendLine Method (PipeServer Component)

This method sends a string followed by a new line.

Syntax

public void SendLine(string connectionId, string text);

Async Version
public async Task SendLine(string connectionId, string text);
public async Task SendLine(string connectionId, string text, CancellationToken cancellationToken);
Public Sub SendLine(ByVal ConnectionId As String, ByVal Text As String)

Async Version
Public Sub SendLine(ByVal ConnectionId As String, ByVal Text As String) As Task
Public Sub SendLine(ByVal ConnectionId As String, ByVal Text As String, cancellationToken As CancellationToken) As Task

Remarks

This method is used to send data with line-oriented protocols. The line is followed by CRLF ("\r\n") .

Please refer to the GetLine method and SingleLineMode property for more information.

Shutdown Method (PipeServer Component)

This method shuts down the server.

Syntax

public void Shutdown();

Async Version
public async Task Shutdown();
public async Task Shutdown(CancellationToken cancellationToken);
Public Sub Shutdown()

Async Version
Public Sub Shutdown() As Task
Public Sub Shutdown(cancellationToken As CancellationToken) As Task

Remarks

This method shuts down the server. Calling this method is equivalent to calling StopListening and then breaking every client connection by calling Disconnect.

StartListening Method (PipeServer Component)

This method starts listening for incoming connections.

Syntax

public void StartListening();

Async Version
public async Task StartListening();
public async Task StartListening(CancellationToken cancellationToken);
Public Sub StartListening()

Async Version
Public Sub StartListening() As Task
Public Sub StartListening(cancellationToken As CancellationToken) As Task

Remarks

To stop listening for new connections, call StopListening. To stop listening for new connections and to disconnect all existing clients, call Shutdown.

StopListening Method (PipeServer Component)

This method stops listening for new connections.

Syntax

public void StopListening();

Async Version
public async Task StopListening();
public async Task StopListening(CancellationToken cancellationToken);
Public Sub StopListening()

Async Version
Public Sub StopListening() As Task
Public Sub StopListening(cancellationToken As CancellationToken) As Task

Remarks

This method stops listening for new connections. After being called, any new connection attempts will be rejected. Calling this method does not disconnect existing connections.

To stop listening and to disconnect all existing clients, call Shutdown instead.

Connected Event (PipeServer Component)

Fired immediately after a connection completes.

Syntax

public event OnConnectedHandler OnConnected;

public delegate void OnConnectedHandler(object sender, PipeserverConnectedEventArgs e);

public class PipeserverConnectedEventArgs : EventArgs {
  public string ConnectionId { get; }
}
Public Event OnConnected As OnConnectedHandler

Public Delegate Sub OnConnectedHandler(sender As Object, e As PipeserverConnectedEventArgs)

Public Class PipeserverConnectedEventArgs Inherits EventArgs
  Public ReadOnly Property ConnectionId As String
End Class

Remarks

This event fires immediately after a client connects. The ConnectionId parameter identifies the client connection.

DataIn Event (PipeServer Component)

This event is fired when data come in.

Syntax

public event OnDataInHandler OnDataIn;

public delegate void OnDataInHandler(object sender, PipeserverDataInEventArgs e);

public class PipeserverDataInEventArgs : EventArgs {
  public string ConnectionId { get; }
  public string Text { get; }
public byte[] TextB { get; } public bool EOL { get; } }
Public Event OnDataIn As OnDataInHandler

Public Delegate Sub OnDataInHandler(sender As Object, e As PipeserverDataInEventArgs)

Public Class PipeserverDataInEventArgs Inherits EventArgs
  Public ReadOnly Property ConnectionId As String
  Public ReadOnly Property Text As String
Public ReadOnly Property TextB As Byte() Public ReadOnly Property EOL As Boolean End Class

Remarks

Trapping the DataIn event is your only chance to get the data coming from the other end of the connection specified by ConnectionId. The incoming data are provided through the Text parameter.

EOL indicates whether or not the EOL string was found at the end of Text. If the EOL string was found, then EOL is True.

If Text is part of the data portion of length larger than either DefaultMaxLineLength or MaxLineLength with no EOL strings in it, then EOL is False. Please note that this means that one or more DataIn events with EOL set to False can be received during a connection.

If the EOL property is "" (empty string), then EOL can be disregarded (it is always True).

Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.

Disconnected Event (PipeServer Component)

Fires when a client disconnects.

Syntax

public event OnDisconnectedHandler OnDisconnected;

public delegate void OnDisconnectedHandler(object sender, PipeserverDisconnectedEventArgs e);

public class PipeserverDisconnectedEventArgs : EventArgs {
  public string ConnectionId { get; }
}
Public Event OnDisconnected As OnDisconnectedHandler

Public Delegate Sub OnDisconnectedHandler(sender As Object, e As PipeserverDisconnectedEventArgs)

Public Class PipeserverDisconnectedEventArgs Inherits EventArgs
  Public ReadOnly Property ConnectionId As String
End Class

Remarks

This event fires when a client disconnects. The ConnectionId parameters identifies the client that is disconnected.

Error Event (PipeServer Component)

This event fires information about errors during data delivery.

Syntax

public event OnErrorHandler OnError;

public delegate void OnErrorHandler(object sender, PipeserverErrorEventArgs e);

public class PipeserverErrorEventArgs : EventArgs {
  public string ConnectionId { get; }
  public int ErrorCode { get; }
  public string Description { get; }
}
Public Event OnError As OnErrorHandler

Public Delegate Sub OnErrorHandler(sender As Object, e As PipeserverErrorEventArgs)

Public Class PipeserverErrorEventArgs Inherits EventArgs
  Public ReadOnly Property ConnectionId As String
  Public ReadOnly Property ErrorCode As Integer
  Public ReadOnly Property Description As String
End Class

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally, the component throws an exception.

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

ConnectionId indicates the connection for which the error is applicable.

ReadyToSend Event (PipeServer Component)

Fired when the component is ready to send data.

Syntax

public event OnReadyToSendHandler OnReadyToSend;

public delegate void OnReadyToSendHandler(object sender, PipeserverReadyToSendEventArgs e);

public class PipeserverReadyToSendEventArgs : EventArgs {
  public string ConnectionId { get; }
}
Public Event OnReadyToSend As OnReadyToSendHandler

Public Delegate Sub OnReadyToSendHandler(sender As Object, e As PipeserverReadyToSendEventArgs)

Public Class PipeserverReadyToSendEventArgs Inherits EventArgs
  Public ReadOnly Property ConnectionId As String
End Class

Remarks

The ReadyToSend event indicates that the underlying pipe is ready to accept data after a failed DataToSend. The event is also fired immediately after a connection to the remote host is established.

PipeConnection Type

A currently connected client.

Remarks

This type describes the connection of a client which is currently connected to the component. The connection may be managed using the different fields of this type.

Fields

AcceptData
bool

Default Value: True

Setting this field to false temporarily disables data reception (and the DataIn event) for the connection. Setting this to true re-enables data reception.

Note: It is recommended to use the PauseData or ProcessData method instead of setting this property.

BytesSent
int (read-only)

Default Value: 0

This field shows how many bytes were sent after the last assignment to DataToSend. Please check DataToSend for more information.

Note: This field will always return 0 when the component is operating in the synchronous mode (i.e., the Timeout property is set to a positive value).

Connected
bool

Default Value: False

This field is used to disconnect individual connections and/or show their status.

The Connected field may be set to false to close the connection.

Connected also shows the status of a particular connection (connected/disconnected).

Note: It is recommended to use the Connect or Disconnect method instead of setting this property.

ConnectionId
string (read-only)

Default Value: ""

This field contains an identifier generated by the component to identify each connection. This identifier is unique to this connection.

DataToSend
string

Default Value: ""

This field contains a string of data to be sent to the remote host. It is a write-only property.

Assigning a string to the DataToSend makes the component send the string to the remote host. The Send method provides similar functionality.

When Timeout is set to 0 and SSLEnabled is set to False, the component will behave asynchronously. If you are sending data to the remote host faster than it can process it, or faster than the network's bandwidth allows, the outgoing queue might fill up. When this happens, the operation fails with exception 10035: "[10035] Operation would block" (WSAEWOULDBLOCK). You can check this error, and then try to send the data again. . The BytesSent property shows how many bytes were sent (if any). If 0 bytes were sent, then you can wait for the ReadyToSend event before attempting to send data again.

Note: The ReadyToSend event is not fired when part of the data is sent successfully.

When SSLEnabled is True or Timeout is set to a positive value, the component behaves synchronously.

Note: It is recommended to use the Send or SendBytes method instead of setting this property.

DataToSendB
byte []

Default Value: ""

This field contains a string of data to be sent to the remote host. It is a write-only property.

Assigning a string to the DataToSend makes the component send the string to the remote host. The Send method provides similar functionality.

When Timeout is set to 0 and SSLEnabled is set to False, the component will behave asynchronously. If you are sending data to the remote host faster than it can process it, or faster than the network's bandwidth allows, the outgoing queue might fill up. When this happens, the operation fails with exception 10035: "[10035] Operation would block" (WSAEWOULDBLOCK). You can check this error, and then try to send the data again. . The BytesSent property shows how many bytes were sent (if any). If 0 bytes were sent, then you can wait for the ReadyToSend event before attempting to send data again.

Note: The ReadyToSend event is not fired when part of the data is sent successfully.

When SSLEnabled is True or Timeout is set to a positive value, the component behaves synchronously.

Note: It is recommended to use the Send or SendBytes method instead of setting this property.

EOL
string

Default Value: ""

The EOL field is used to define boundaries in the input stream using the value of the field.

The EOL field is especially useful with ASCII files. By setting it to CRLF ("\r\n") , the incoming ASCII text stream can be split into lines. In this case, one event is fired for each line received (as well as in packet boundaries). The CRLF ("\r\n") . bytes are discarded.

The EOL field is a binary string. This means that it can be more than one byte long, and it can contain NULL bytes.

EOLB
byte []

Default Value: ""

The EOL field is used to define boundaries in the input stream using the value of the field.

The EOL field is especially useful with ASCII files. By setting it to CRLF ("\r\n") , the incoming ASCII text stream can be split into lines. In this case, one event is fired for each line received (as well as in packet boundaries). The CRLF ("\r\n") . bytes are discarded.

The EOL field is a binary string. This means that it can be more than one byte long, and it can contain NULL bytes.

MaxLineLength
int

Default Value: 2048

This field is the size of an internal buffer that holds received data while waiting for an EOL string.

If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.

If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.

The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.

SingleLineMode
bool

Default Value: False

This field shows the special mode for line-oriented protocols. When SingleLineMode is True, the component treats the incoming data stream as lines separated by carriage return (CR), line feed (LF), or CRLF. The EOL property is ignored.

Timeout
int

Default Value: 0

This field specifies a timeout for the component.

This field defines the timeout when sending data. When SSLEnabled is False, a value of 0 means data will be sent asynchronously and a positive value means data will be sent synchronously. When SSLEnabled is True, all data is sent synchronously regardless of the Timeout value. Please see the following notes for details.

Plaintext

If the Timeout field is set to 0, all operations return immediately, potentially failing with a WOULDBLOCK error if data cannot be sent immediately.

If Timeout is set to a positive value, data is sent in a blocking manner and the component will wait for the operation to complete before returning control. The component will handle any potential WOULDBLOCK errors internally and automatically retry the operation for a maximum of Timeout seconds.

SSL

If the Timeout field is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If Timeout is set to a positive value, the component will wait for the operation to complete before returning control.

Additional Notes

The component will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.

If Timeout expires, and the operation is not yet complete, the component throws an exception.

Please note that by default, all timeouts are inactivity timeouts, i.e. the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.

The default value for the Timeout field is 0 (asynchronous for plaintext, synchronous for SSL).

UploadStream
System.IO.Stream

Default Value: ""

Setting this field uploads the data in the specified stream to the current connection. The component will automatically close this stream if CloseStreamAfterTransfer is True (default).

Note: It is recommended to use the SetUploadStream method instead of setting this property.

Constructors

public PipeConnection();
Public PipeConnection()

Config Settings (PipeServer Component)

The component accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.

PipeServer Config Settings

CloseStreamAfterTransfer:   If true, the component will close the upload or download stream after the transfer.

This setting determines whether the input or output stream is closed after the transfer completes. When set to True (default), all streams will be closed after a transfer is completed. In order to keep streams open after the transfer of data, set this to False. the default value is True.

CustomSecurityDescription:   A custom security descriptor to define access to the pipe.

Specified in the Security Descriptor Definition Language format. For example, if there is an instance of PipeServer running as a Windows Service, the correct SDDL string must used in the Config method for a Desktop app to access the pipe, like so: PipeServer1.Config("CustomSecurityDescription=D:(A;OICI;GRGW;;;AU)");

InBufferSize:   The size in bytes of the output buffer.

This setting specifies the size in bytes of the output buffer. Small buffer sizes may reduce overall performance. The default value is "65536".

OutBufferSize:   The size in bytes of the input buffer.

This setting specifies the size in bytes of the input buffer. Small buffer sizes may reduce overall performance. The default value is "65536".

Base Config Settings

BuildInfo:   Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

GUIAvailable:   Whether or not a message loop is available for processing events.

In a GUI-based application, long-running blocking operations may cause the application to stop responding to input until the operation returns. The component will attempt to discover whether or not the application has a message loop and, if one is discovered, it will process events in that message loop during any such blocking operation.

In some non-GUI applications, an invalid message loop may be discovered that will result in errant behavior. In these cases, setting GUIAvailable to false will ensure that the component does not attempt to process external events.

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a component is using. It will return the following information:

  • Product: The product the license is for.
  • Product Key: The key the license was generated from.
  • License Source: Where the license was found (e.g., RuntimeLicense, License File).
  • License Type: The type of license installed (e.g., Royalty Free, Single Server).
  • Last Valid Build: The last valid build number for which the license will work.
MaskSensitive:   Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to true to mask sensitive data. The default is true.

This setting only works on these components: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

UseInternalSecurityAPI:   Whether or not to use the system security libraries or an internal implementation.

When set to false, the component will use the system security libraries by default to perform cryptographic functions where applicable. In this case, calls to unmanaged code will be made. In certain environments, this is not desirable. To use a completely managed security implementation, set this setting to true.

Setting this configuration setting to true tells the component to use the internal implementation instead of using the system security libraries.

On Windows, this setting is set to false by default. On Linux/macOS, this setting is set to true by default.

If using the .NET Standard Library, this setting will be true on all platforms. The .NET Standard library does not support using the system security libraries.

Note: This setting is static. The value set is applicable to all components used in the application.

When this value is set, the product's system dynamic link library (DLL) is no longer required as a reference, as all unmanaged code is stored in that file.
