Shuts down the platform and all known endpoints.

public:
 IAsyncResult ^ BeginShutdown(AsyncCallback ^ userCallback, System::Object ^ state);

public IAsyncResult BeginShutdown (AsyncCallback userCallback, object state);

member this.BeginShutdown : AsyncCallback * obj -> IAsyncResult

Public Function BeginShutdown (userCallback As AsyncCallback, state As Object) As IAsyncResult

Parameters

userCallback: AsyncCallback

The method to be called when the asynchronous operation is completed.

state: Object

A user-provided object that distinguishes this particular asynchronous operation from other asynchronous operations.

Returns

IAsyncResult

An IAsyncResult that references the asynchronous operation.

Examples

The example shows how to shutdown a platform. The example assumes that a platform was previously started successfully. Applications can always attempt to shutdown a platform without error even if it is already shut down.

C# Platform uninitialization


platform.BeginShutdown(this.PlatformShutdownCompleted, platform /*state*/);


private void PlatformShutdownCompleted(IAsyncResult result)
{
    // Platform shutdown never throws, but EndShutdown needs to be called
    // to ensure resources are freed.
    CollaborationPlatform platform = result.AsyncState as CollaborationPlatform;
    platform.EndShutdown(result);
    Console.WriteLine("Platform shutdown completed.");

}

Remarks

When it is shut down, the platform terminates all the endpoints and frees all its resources. The platform cannot be used after this completes.

This operation should never throw.
