--- Comment #4 from Rainer Schuetze <r.sagita...@gmx.de> --- The newest version https://github.com/dlang/visuald/releases/tag/v0.45.0-beta1 uses generic dependency tracking for the compiler, too. So you might get hit by this issue again with the next version. If you are still using VS2005, I'd recomment installing some MS package containing the file access tracker.exe. It should be part of anything containing MSBuild, e.g. .NET SDK, Build Tools or other SDKs. --
