I'm migrating a C++/CLI project from VS2008 to VS2017 but I always get an error when "reloading" the project to convert.
The project don't load and I don't see any clear error message about the reason.

visual studio 2017 safemode

After I installed an extension to Visual Studio 2017 Enterprise, VS crashes on startup. In previous versions there was a /safemode switch. I tried it but it seems to be no longer supported. What can I do to suppress loading of extensions in Visual Studio when it crashes (cannot disable extensions via extension manager).
Thanks
There is still a /SafeMode switch. If this does not help you need to do a repair on visual studio 2017
