I have tried your code and it works fine. But I have a question. Why does it work with the MatchesCore method? I mean, should we always use the MatchesCore method when we want to match null and empty strings?23Hi Saeed,We have made a fix in the latest internal build (2013.3.1117.40) to support the Matches method when using null and empty strings. You can download the latest internal build from our official website Regards,Boyan BoevTelerik24I have tried the latest internal build (2013.3.1117.40) and it works fine. But now I have another question. I have a class that has a method that takes a string parameter. This method calls another method that takes a string parameter. I want to mock the second method and I want to match the first string parameter with null and empty strings. But I don't want to match the second string parameter with null and empty strings. How can I do this?
