Ctrl + Dot (ShowSmartTag) not working in Visual Studio 2012

Question

I\'m now using the Visual Studio 2012, and now the keyboard shortcut for \"ShowSmartTag\", Ctrl + ., is not working. I googled a bit found so

Answer 1

On my PC the problem occurs mostly when renaming a method or a parameter ...

To analyze this I have started a first VS 2012 instance without starting to edit the source code. Then I have started a second instance of VS 2012 which must be attached to the first VS instance:

• Debug->Attach to Process
• Look for devenv.exe, Title = title of the VS main window
• Select Managed and Native Code
• Attach

Enable Break when exception occurs:

• Debug->Exceptions
• Enable C++ Exceptions, Common Language Runtime Exceptions
• OK

Now as I started to edit a parameter name in the first VS instance, an error was thrown and the debugger in the second instance showed me an error in an memory Profiler Add-In. After I have uninstalled the Add-in, the ShowSmartTag called by the keyboard works fine again.
