.NET Core

You can use CS-Script plugin to execute scripts targeting .NET 5/Core. It is possible even though the plugin itself is hosted on .NET Framework and the script engine file included in the plugin distro is targeting .NET Framework.

You can retarget the execution and syntax support to .NET 5 by manually enabling services as it is described here:

• Enable CS-Script for .NET 5
• Enable Lates C# syntax support for .NET 5

Alternatively, you can just click "Enable .NET 5/Core integration" and follow the instructions
