Hotkeys no longer work in Visual C# 2010 Express

Suddenly none of hotkeys in C# Express work (like F5, F6 etc.). I don'开发者_运维技巧t know what I've done, but no doubt its something stupid. Does anyone know how to fixed this?

I have tried the Keyboard settings in Options, but it won;t even let me add hotkeys for some reason, even once I've removed the old ones. So re-adding them does not work.

Reset your Visual Studio Settings. If that doesn't help repair your Visual Studio.

• Try restarting your computer.
• Have you made any changes recently (Installed a new Add-in or some other software on your PC).
• Do the hot keys work in other applications? If no then it has nothing to do with VS.
• Did you try a different keyboard?

You can try some of the Visual Studio standard trouble shooting steps described here. These are for the non-Express-editions, but I guess they will also work for the Express versions. Have a look especially at resetting all settings and check for add-ons.
