This has been pissing me off a lot recently. It seems to happen after I've rebased and then tried to recompile my solution at random time. Visual Studio complains that it can't compile the solution because the 'roslyn' folder within the 'bin' folder is locked:
The obvious solution is to try and delete the folder, however, when you go to delete it, Windows moans the file's locked. I use a file unlock program called 'What Is Locking This File?' and that doesn't always fix it, I've also shut down my solution with no luck and a few times I've also closed VS without the issue going away!!! To fix the issue, in Task Explorer, find the 'VBCSCompiler.exe' process(es) and KILL IT(them).
