Bits of .NET

Sometimes Visual Studio fails to rebuild even after a full Clean + Rebuild.
The reason is not your code — it’s VS holding file handles in its internal cache (especially after crashes or forced shutdowns).

Why this matters:
Locked DLLs cause ghost errors, outdated binaries, and “it works on my machine” nightmares.

The fix (safe & instant):

taskkill /f /im devenv.exe
rd /s /q .vs
rd /s /q bin
rd /s /q obj
