The DoInstead() method can be used only with a standard delegate type. The workaround is to use the custom delegate type in the Arrange() method, as shown below:You can find more information in the documentation Regards,StefanTelerik14I am using the latest version of JustMock (2013.1.301.3) and I am still getting this error. I am using the following code:15var mock = Mock.Create<DoInsteadWithCustomDelegate>();16Mock.Arrange(() => mock.DoSomething()).DoInstead(() => Console.WriteLine("This is a test"));17mock.DoSomething();18Hello Mike,The issue is fixed and will be available in the next internal build of JustMock. The workaround is to use the custom delegate type in the Arrange() method, as shown below:Regards,StefanTelerik
