I really like Visual Studio 2012 because the GUI is very fast and flexible. The problem is that i need VC++-Compiler for VS2010. Is it somowhow possible to setup old compilers, SDKs in VS 2012. I really hate the VS 2010-Gui because it's really slow and lagging around.
Any ideas?
Yes, just modify the platform toolset (reference):
Property Pages->Configuration Properties->General
, then click Platform Toolset
and select the toolset you want. Depending on what you have installed, you should see v90 for MSVC2008 and v100 for MSVC2010.
There is also more detailed info here.
