Is there currently any way to enable c# 6?
My project (which utilizes c# 6 syntax) which compiles fine in visual studio 14 fails in appveyor

    Have you tried to use the Visual Studio 2015 CTP OS like described in this blog post:
    http://www.appveyor.com/blog/2015/01/20/visual-studio-2015-ctp-image
    I think this could be the issue.

    That is a start but I still can't get the build to use msbuild 14; it keeps trying to use 12.

    the part about "Add this command to install section of your build config if you need msbuild command to call MSBuild 14.0 by default:

    set PATH=C:\Program Files (x86)\MSBuild\14.0\Bin;%PATH%"

    doesn't seem to have any effect

    An update; I got it to work by changing from msbuild to build script as follows: msbuild "Src\TW.CommentSubsystem.Core.sln" /verbosity:minimal /logger:"C:\Program Files\AppVeyor\BuildAgent\Appveyor.MSBuildLogger.dll"

    Maybe the msbuild task ise hardcoded to use version 12?

    It takes Visual Studio version from .sln file. If it's VS 2013 then MSBuild 12.0 is used.

    I deleted/recreated the .sln inside visual studio 2015 and that resulted in a .sln file looking like "Microsoft Visual Studio Solution File, Format Version 12.00
    # Visual Studio 14
    VisualStudioVersion = 14.0.22512.0
    MinimumVisualStudioVersion = 10.0.40219.1 [...]"

    after checking this in it still was built with msbuild 12

    Just for fun I also tried manually editing the "Format Version" to 14 but no cigar either.

    Then leave "script" build mode for now. We'll add VS 2015 support to support automatic "MSBuild" build mode.
