Mocking Encoding.UTF8.GetBytes throws NotImplementedException

[Andrew]

Trying to arrange Encoding.UTF8.GetBytes to return some bytes is throwing an NotImplementedException with the message "You can't call the original implementation of a method that does not have one (abstract or interface method). I'm able to successfully mock out Encoding.UTF8.GetString in the exact same way, so this confuses me. Is it a bug?

Hi,

I am really sorry for the inconvenience!

Could you please send us a complete sample that demonstrates the issue? 

I tried with 

Mock.Arrange(() => Encoding.UTF8.GetBytes(Arg.AnyString)).Returns(new byte[] { });
var bytes = Encoding.UTF8.GetBytes("sample");

and it is working on my side. I am sorry if I am missing something.

Regards,
Svetlozar
