Visual Studio 2015 Syntax highlighting in C Project

Question

I've got a big problem with VS2015. In .c files or .cpp there aren't a syntax highlighting.

1. loaded settings from my friend -> didn't work
2. reinstalled -> didn't work
3. ask my Prof. -> he looked in my settings and haven't an idea because all is ok

Can you help me? It's like windows notepad.

edit: I updated VS2015 now and the syntax highlighting works. :)

Answer 1

Start VS2015 with command-line options /ResetUserData or /ResetSettings, eg:

"C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\devenv.exe" /ResetUserData

and/or:

"C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\devenv.exe" /ResetSettings

You will lose all your user settings and recent projects/files list 您将丢失所有用户设置和最近的项目/文件列表
