I seem to be having an issue with the IDE whereby it has compiler errors suggesting an older language version, but I set everything up to be the latest I could find. This is an example of the errors I have:
In my csproj file I have:
And I have a Calpurnius.csproj.DotSettings with CSharpLanguageProject/LanguageLevel/@EntryValue">CSharp60</s:String>
My System dll is: C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6.1\System.dll
Does anyone know why it might think I'm still on an old language version and give those errors?
