Solution : Predefined type 'System.Runtime.CompilerServices.IAsyncStateMachine' is not defined or imported

Predefined type 'System.Runtime.CompilerServices.IAsyncStateMachine' is not defined or importedThis is because of targeting the wrong .NET framework version. For async to work out of the box you need to target your application to .NET 4.5 (at the minimum). Go ahead continue !!
