Where did the build configuration manager go?

I just had a strange problem with Visual Studio I could not debug my Unit Tests. It just kept running in release mode no matter what I tried and the Build Configuration Manager was completely gone from the context menu of the solution and no build configuration in the project settings either.

Funny thing to run into at 4am… NOT! Well the solution is quite easy:

1. Click on “Tools” in the menu bar
2. Select Options
3. Navigate to “Projects and Solutions”
4. Make sure the checkbox “Show advanced build configurations” is checked

Now everything is back to normal though I have no friggin idea why it was missing to start with….
