我想你错过了打字。
The right class name is Task
not Tasks
and it belongs on System.Threading.Tasks
namespace.

The correct class (and namespace) name is System.Threading.Tasks.Task
which is located in mscorlib.dll
and is available in .NET 4
+. If you want to use it in .NET 3.5
, you can do this by using Microsoft Reactive Extensions.
