Answer 1

I had the same problem with Microsoft Visual Studio 2013 Premium.

Fixed it by following the steps:

1. Close your solution.
2. Delete hidden .suo file in folder where your solution's .sln file exists.
3. Open your solution.
4. Rebuild your solution.

F12 should now work.

Answer 2

I am working on a solution with C++ combined with C# which is set to VS 2010 compiler but I edit it with the 2013 IDE. All of this is orchestrated with the MS-TFS. I searched for both *.ncb and *.sou files but couldn't find them. Eventually I saw eodabash's comment of changing the File Extension option, and hey presto, it works for me...

Answer 3

For me, rebuilding the solution, then closing the file in visual studio and reopening it fixed it.

Answer 4

To reiterate what @eodabash said on 2014-04-07 was EXACTLY it.

I'm using Visual Studio 2013 Premium and I too lost Go To Definition functionality when the file was file containing the class was not opened.

Resolution:

1. Tools > Options > Text Editor > File Extension
2. Notice extension, "cs" was missing from list.
3. Type, "cs" in the Extension box
4. Select, "Microsoft Visual C#" under Editor
5. Click, Add. Click, Ok.

BOOM!

My issue was NOT an extension. It was NOT the .suo files. It was NOT a reinstall issue. It worked in C++ but NOT C#.

It WAS the file extensions option were not associated with C#. (facepalm)

Answer 5

Verify the source file is part of the solution you have open. - Sigh.

(For me, I was looking for 'Go to Definition' for a source file in a completely different solution than what I had opened in Visual Studio. I opened the correct solution, verified 'Go To Definition' was functional, then grabbed a much needed cup of coffee.)
