OnMethodInvokeBaseAdvice.UnsupportedTargetAction Property


Specifies the action to take when the advice is applied to an async method with unsupported return value type.

public UnsupportedTargetAction UnsupportedTargetAction { get; set; }
Property Value
Type Description

Starting with C#7 async methods can have return types other than Task or Task<TResult>. Async method interception does not support this type of async methods. By default, the build error is raised whenever async method interception is applied to a method that returns awaitable type other than Task or Task<TResult>.

Set this property to change how unsupported async methods are handled during compile time.
