I have changed my computer’s name and my username, and got an error in Visual Studio 2010 when I tried to use data diagram. Today I installed Visual Studio 2012 and found that there is no “Data Diagram” at all. My question is, was there the “Data Diagram” in Visual Studio 2012 in the original installation? Did I corrupt it by changing my computer and user identities?
Anyone who has installed Visual Studio 2012 please help me.
Sorry to answer my own question,but i may found the real answer to my question.
