You should only open projects from a trustworthy source prompt

In Visual Studio 2017 and previous versions, if you attempt to open a project on a network share, such as one located on a Mac, that helpful, but rather annoying message prompts you. There’s a quick fix for that;

  • Open Visual Studio, on the Tools  menu, click Options.
  • In the Options dialogue box, on the list on the left, expand Projects and Solutions and click General.
  • Uncheck Warn user when the project location is not trusted, and click OK.
