Recovering file from the Visual Studio document cache?
Sorted it. Those recovery files are located @ MyDocuments\Visual Studio X\Backup Files\Project Name...
If you have compiled the code into a DLL, then you can use ILSpy, or Reflector to decompile that back into code.
Visual Studio 2019.4.1 had my backup files in %localappdata%\Microsoft\VisualStudio\BackupFiles
- the folders in the MyDocuments tree were empty.
