It seems that VSTS does not support C # 7, since I get a build error that will indicate the use of the C # 6 compiler. How do I enable C # 7 or what am I doing wrong? I am using Visual Studio 2017, focusing on .NET 4.6.1.
I would prefer not to return the C # 7 changes that I added, if possible. As you can see in the screenshot of Visual Studio and the console in VSTS, there is a difference in the version of C # used.
