If you are one of those folks that like to work with server OSes vs. desktop OSes like myself, you probably want to install Visual Studio 2012 RTM on Windows Server 2012.
Well, unfortunately, Windows Server 2012 RTM has not yet been released on MSDN, so the more adventurous of us are forced to install VS 2012 RTM on the RC release of Windows Server 2012.
As it turns out, however, Microsoft has completely blocked us from doing that. Since .Net 4.5 ships out-of-the-box with Windows Server 2012, you are unable to install Visual Studio 2012 RTM on the RC release since the RTM release contains a later build of .Net Framework v. 4.5!!
Here is the screenshot from the blocked installation:
So until Microsoft allows us to download the full RTM release of Windows Server 2012, we are forced to rely on Visual Studio 2012 RTM installations either on Windows 8 or Windows 7...
Hopefully we will see the Windows Server 2012 RTM release coming to MSDN very soon!!
