Parameters

Returns

A task whose result is one of the following:

• The service if the request was successful.
• null if the service threw an exception during activation.
• null if the associated package failed to load.
• null if the associated package proffered null.
• null if the associated package could not be found, or the package did not correctly proffer the service.
• null if the environment has starting shutting down and the retrieval would have resulted in a package load.
• Otherwise; null if there was any other failure retrieving the service.

Exceptions

Remarks

Performing an explicit cast of the resulting service to a specific interface could perform a blocking RPC call if the underlying service is STA-bound, which can hang if the UI thread is blocked in a Run(Func<Task>) or Join(CancellationToken). Instead, prefer the generic equivalents GetServiceAsync<TService,TInterface>(Boolean, CancellationToken) and Microsoft.VisualStudio.Shell.ServiceExtensions.GetServiceAsync, noting the difference in behavior around exceptions.

This method is safe to access from any thread.
