When I use Microsoft's Visual C# Compiler (v4.8.4084.0) to build source code from the command line, I get the following error and/or warning:
PS C:\> csc Program.cs
This compiler is provided as part of the Microsoft (R) .NET Framework, but only supports language versions up to C# 5, which is no longer the latest version. For compilers that support newer versions of the C# programming language, see http://go.microsoft.com/fwlink/?LinkID=533240
C# 7.0 language features are currently being developed as part of the Roslyn Project, however the current version of the C# computer language is C# 10. Is it possible to use C# 7.0's advanced features from the command line?
