Requirements: I have been using RoslynPad tools for some code testing, which is a very good cross-platform C# editor that can execute C# code directly without opening the heavyweight VS tool, but it is still not as powerful as the paid version of LINQPad.
LinqPad
LinqPad is a lightweight tool for writing and running C# (VB/F#/SQL) code, a playground for .NET programmers, a must-have tool highly recommended by C# developers, and a tool that you never want to throw away once you use it. The tools are from Joseph Albahari, author of the C# Core Technical Guide, a. Net is a senior technologist who has won 15 Microsoft Most Valuable Expert (MVP) awards.
