How can I build a Visual Studio 2015 solution using C# 6.0 Features at a TFS 2012 without installing Visual Studio 2015 on a build agent (using Microsoft Build Tools 2015 RC)
I Already installed MSBuild Tools but I still get exceptions. How can I Tell my build template to use MSBuild 14 (Only for one project)
And why does my TFS 2012 compile async and await (c# 5.0) without any problems while the BuildAgent only has Visual Studio 2012 installed?
I tried changing the ToolPath of my BuildProcessTemplate to MSBuild/14.0/ but I get a build error:
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Microsoft.CSharp.targets (316): "csc2.exe" exited with code -532462766.
Installing the Microsoft.Net.Compilers 1.0.0-rc2 Compilers gives the same error.
If I compile the project using the command line I get the exact same error / although there is no error on my dev machine when using the command line with the exact same arguments.
This is the Exception I get in the command line:
C:\Program Files (x86)\MSBuild\14.0\bin\csc2.exe /noconfig /nowarn:1701,1702 /nostdlib+ /errorreport:prompt /warn:4 /define:TRACE /highentro.....

Answer
I used TFS2013 U5, but it will be same:
- installed VS2015 RTM on BuildServer machine
- put this into MSBuild arguments in Process part of BuildTemplate
/tv:14.0 /p:GenerateBuildInfoConfigFile=false /p:VisualStudioVersion=14.0
Both compiling and VS-unit tests are now running OK.
