Facebook.Extensions.Tasks is no longer under development. These XTaskAsync() methods are now part of the core Facebook C# SDK starting from v5.3



This library takes the asynchorous programming with Facebook C# SDK to the next level by adding extension methods to FacebookClient and FacebookOAuthClient which returns Task<object>


Getting Started

Reference Facebook.Extensions.Tasks.dll which adds extension methods to FacebookClient and FacebookOAuthClient. To prevent conflicts from existing async methods, these extension methods start with HttpMethod type and ends with TaskAsync( ... ). Even though the dll name is "Facebook.Extensions.Tasks.dll" these extension methods are under the "Facebook" namespace.

Extension methods available for FacebookClient:

GetTaskAsync( ... )
PostTaskAsync( ... )
DeleteTaskAsync( ... )

Extension methods available for FacebookOAuthClient:

GetApplicationAccessTokenTaskAsync( ... )
ExchangeCodeForAccessTokenTaskAsync( ... )


Full samples can be found under the "samples" folder in the source code.

Using with Task Parallel Library (TPL)

private static void ExecuteAsyncMethod()
	var fb = new FacebookClient();
	var task = fb.GetTaskAsync("/4");

		t =>
			if (t.Exception == null)
				dynamic result = t.Result;
				Console.WriteLine("Name: {0}", result.name);
				Console.WriteLine("error occurred");

Note: If you are running the above code under .NET 4.0, you don't need to reference the Async libraries as Task Parallel Library (TPL) comes bundled with .NET 4.0. For Silverlight and Windows Phone 7 Async libraries (AsyncCtpLibrary_Silverlight.dll or AsyncCtpLibrary_Phone.dll) must be referenced as TPL is not present.

Using with async and await

private async static void ExecuteAsyncMethod()
	var fb = new FacebookClient();

		dynamic result = await fb.GetTaskAsync("/4");

		Console.WriteLine("Name: {0}", result.name);
	catch (FacebookApiException ex)

Note: Reference the appropriate Async libraries (AsyncCtpLibrary.dll or AsyncCtpLibrary_Silverlight.dll or AsyncCtpLibrary_Phone.dll). You need to reference AsyncCtpLibrary.dll for .NET 4.0 also in this case unlike the example with TPL.
