title: 'the type or namespace could not be found' in Visual Studio 2017
body: <p>Every time I do a git pull from remote to update my branch, Visual Studio 2017 shows "the type or namespace could not be found" error in many files as I open them. Interestingly I don't see the problem in Visual Studio 2015 for the same projects/repo. The software builds fine in both versions of Visual Studio so it is a false error. Doing a Clean or Rebuild doesn't fix the problem. I end up re-cloning the repo from remote and then Visual Studio 2017 is happy. Any one knows how to fix this annoying problem?</p>
