C# : Does it have a repl?

As a procedural language (though it’s becoming more and more functional-like with each release) C# isn’t exactly designed to work with a REPL, but I think Visual Studio (the IDE, not the text editor) comes with an immediate window that works as one, and a quick internet search finds many third party ones, like .NET fiddle for the web, or CSharpRepl for the command line.
