For the last 24 hours I had problems compiling one of specific project.
The project won’t compile because apparently: “O/R Designer validation failed for file: <FileName>.dbml Error: The operation could not be completed. Unspecified error”. The weird thing was that I didn’t change anything in that project, in fact that project was not changed since the beginning of this year when a single comment was added in one of the project’s files.
It seems that the project was not to blame. Further checking of Visual Studio showed that indeed he was probably the cause of the problem.
To cut a long story short the problem was easily solved by running devenv /ResetSkipPkgs (- thanks Yury).
Visual Studio (devenv) has some other useful command line parameter you should know about:
Next time when VS causes you grief and you contemplate on re-installing it (only takes 4 hours) try running devenv from the command line instead.
