Visual Studio 2015 environment with C # projects

My visual studio 2015 RC crashes when I open either an existing C # project or create a new C # project. This is not a failure if I create or open a project in C ++.

Here is the stack:

I had a problem with VS 2015 Enterprise RC and RTM. I noticed that VS 2015 RTM displays duplicate project templates (for example, the C # console application has been specified twice).

I think that the VS 2015 RC removal procedure, which was performed prior to the installation of VS 2015 RTM, left some things on my machine that caused problems.

This is what I did to fix the problem on my machine (test system, not my everyday machine for developers (!)):

  • create system restore point
  • remove VS 2015 RC
  • manually delete the folder: C: \ Program Files (x86) \ Microsoft Visual Studio 14.0
  • manually delete the folder: C: \ Users \\ AppData \ Local \ Microsoft \ VisualStudio \ 14.0
  • manually delete the folder: C: \ Users \\ AppData \ Roaming \ Microsoft \ VisualStudio \ 14.0
  • reboot
  • reinstall RTM VS 2015 (some problems are displayed)
  • fixed VS 2015 RTM

Now everything works as expected.
