This works fine for methods that don't have any parameters, but when we try to invoke a method with parameters, we get a "System.Reflection.TargetParameterCountException" exception. We are using the following code to create the dynamic method:We are using the latest JustMock version (2017.3.1014.1).Is there something we are missing here?Thanks,Paul
