I encounter the following issue and/or warning when using Microsoft's Visual C# Compiler (v4.8.4084.0) to compile source code from the command line:
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
Although C# 10 is the most recent version of the C# programming language, C# 7.0 language features are currently being developed as part of the Roslyn Project. Is it possible to utilise the command line to access features of the C# 7.0 or higher language?
