public:
System::Threading::Tasks::Task ^ CallExtensionPointAsync(Func<System::Threading::Tasks::Task ^> ^ asyncAction);
public System.Threading.Tasks.Task CallExtensionPointAsync (Func<System.Threading.Tasks.Task> asyncAction);
abstract member CallExtensionPointAsync : Func<System.Threading.Tasks.Task> -> System.Threading.Tasks.Task
Public Function CallExtensionPointAsync (asyncAction As Func(Of Task)) As Task
Parameters
Returns
A Task that asynchronously executes the asyncAction
.
Remarks
This class supports the Visual Studio infrastructure and in general is not intended to be used directly from your code.
Applies to
CallExtensionPointAsync(Object, Func<Task>)
Makes a guarded call to an async extension point.
public:
System::Threading::Tasks::Task ^ CallExtensionPointAsync(System::Object ^ errorSource, Func<System::Threading::Tasks::Task ^> ^ asyncAction);
public System.Threading.Tasks.Task CallExtensionPointAsync (object errorSource, Func<System.Threading.Tasks.Task> asyncAction);
abstract member CallExtensionPointAsync : obj * Func<System.Threading.Tasks.Task> -> System.Threading.Tasks.Task
Public Function CallExtensionPointAsync (errorSource As Object, asyncAction As Func(Of Task)) As Task
Parameters
- errorSource
- Object
Reference to the extension object or event handler that may throw an exception. Used for tracking performance and errors.
Returns
A Task that asynchronously executes the asyncAction
.
Remarks
The implementation in Visual Studio handles and ignores OperationCanceledException.
Applies to
CallExtensionPointAsync<T>(Func<Task<T>>, T)
Makes a guarded call to an async extension point.
public:
generic <typename T>
System::Threading::Tasks::Task<T> ^ CallExtensionPointAsync(Func<System::Threading::Tasks::Task<T> ^> ^ asyncCall, T valueOnThrow);
public System.Threading.Tasks.Task<T> CallExtensionPointAsync<T> (Func<System.Threading.Tasks.Task<T>> asyncCall, T valueOnThrow);
abstract member CallExtensionPointAsync : Func<System.Threading.Tasks.Task<'T>> * 'T -> System.Threading.Tasks.Task<'T>
Public Function CallExtensionPointAsync(Of T) (asyncCall As Func(Of Task(Of T)), valueOnThrow As T) As Task(Of T)
Type Parameters
- T
The type of the value returned from the asyncCall
.
Parameters
- valueOnThrow
- T
The value returned if the delegate call failed.
Returns
A Task<TResult> that asynchronously executes the asyncCall
or provides valueOnThrow
.
Remarks
The implementation in Visual Studio handles and ignores OperationCanceledException.
