Release v3.21.0

Use choco install cs-script to deploy the release (instructions on how to use/enable choco).
If you prefer manual install then avoid using WinZip or WinRar as they lead to locking the downloaded content. Use 7zip instead.

Extension Pack contains some additional content representing somewhat less mainstream functionality and experimental features. For installing it extract cs-script.ExtensionPack.7z archive to your install location (e.g. C:\ProgramData\chocolatey\lib\cs-script\tools\cs-script).

The most important features of this release are related to the Linux and Mono integration. Another important change are the features that improve user experience of using CS-Script on it's own without advanced tools (e.g. Visual Studio).

• Linux gains NuGet support.
• Finally you can execute C# 6 scripts with Mono evaluator (previously only CS-Script's CodeDom and Roslyn engines supported that):

CSScript.EvaluatorConfig.Engine = EvaluatorEngine.Mono

dynamic script = CSScript.Evaluator
                          .LoadMethod(@"using System;
                                        public void Print(object a, object b)
                                        {
                                            Console.WriteLine($"{a} {b}");
                                        }");

script.Print(1, 2);

• The Python-like "print" functionality has been extended to support collections:

using System;
using System.IO;

void main()
{
    print(Directory.GetFiles(".", "*"));
}

Will produce:
