Visual Studio "Rebuild all failed"
c#, visual-studio-2010
Solution
Not an answer per se - but you're better off looking at the output window and seeing what it says there.
Also, to help with that you might want to look at your MSBuild verbosity - as shown on this screenshot (last two options):
Beware - the highest level generates a MASSIVE amount of information.
Finally - running `msbuild` from the solution folder in a command prompt will really nail the issue - because error messages and warnings come up in red and yellow respectively.
Problem
Why does Rebuild fail with no errors? Since this morning, this error keeps showing up. I build the entire solution (25 C# managed projects) and a "Rebuild All failed" appears, but without any errors! (I have 13 warnings about COM not supporting Generics, but it's "normal" because one dll is exposed as COM.)
