I have some issues with MSBUILD using C# 7 syntax using the VS2017 image at this project (https://ci.appveyor.com/project/geoperez/ffmediaelement).

Am I missing any extra configuration in order to support the MSBUILD to use C# 7?

Thank you

    Hi Geovanni,

    Apparently your build used default (VS2015) image. I sent you PR to use VS2017.

    Yes, as long as you have YAML, it takes over UI, with few exceptions.

    I use Fake for writing build scripts and it can't find MSBuild of version 15, only version 14. It has a configuration option to specify VisualStudio version and msBuildExe file but still can't found MSBuild of version 15, even I specified VS2017. It found MSBuild version 14. Could you help me with the path of version 15?

    You can run where msbuild command at any build stage on Visual Studio 2017 build worker image. Anyway it is C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\MSBuild\15.0\Bin\MSBuild.exe

    If you still have issues, please send us link to the problem build and your build configuration in YAML format (use Export YAML if you use UI).
