I\'m using Visual Studio 2015 to work with Visual Studio 2010 C++ projects. Those projects are not converted and need to stay true 2010 projects.
Compiling works as exp
Ok, the problem is indeed due to language settings.
Settings with issue:
-> project properties missing
This fixed it:
-> project properties there
Unfortunately it is not possible to change language in VS2010 without re-installing. And I don't want to stay with VS2015 in german language :(
UPDATE: I reported that issue at microsoft and they just confirmed it. So this might be fixed in a future update
