Is there an interactive shell for programming quick C# code snippets?

Is there an interactive shell for programming quick code snippets in C#/.NET? Sometimes I'm interested in trying out a quick block of .NET code without creating a whole console application (that I then have to delete when I'm done).

I un开发者_运维问答derstand that the Immediate Window sort of provides this functionality, but it seems like you have to have an application open and be debugging it for the Immediate Window to be of any use.

I was tinkering with Ruby a while back, and the Interactive Ruby Shell (irb) was an invaluable little tool for trying out little snippets of Ruby code. Lightweight and instantaneous. This kind of thing seems like a no-brainer to me. Does anything like it exist for C#/.NET?

LINQPad is very neat for that:

LINQPad is more than a LINQ tool: it's an ergonomic C#/VB/F# scratchpad that instantly executes any expression, statement block or program with rich output formatting – the ultimate in dynamic development. Put an end to those hundreds of Visual Studio Console projects cluttering your source folder!

There isn't a full interactive shell for C#. However, for many things, you can use LINQPad to quickly try out a snippet of C# code. While it's intended for LINQ testing, it works for other C# code as well.

For details, see LINQPad as a Code Snippet IDE.

The Mono project has an interactive shell.

Also, you can use the Snippet Compiler.

Yes, there's one for mono mono-project.com/CsharpRepl

I know this is an old post, but I am new to C#. I actually found a dotnet tool that is pretty much like Java's jshell. To install simply go to powershell and enter:

dotnet tool install dotnet-repl --global

dotnet-repl.exe

There was one published by the Mono Project a while back.

We've just released a small REPL tool for C# with code completion and everything called CShell. http://cshell.net

You can also write scrips and then send them to the REPL or just write your snippets right in the REPL.

It's still in beta, but it works pretty well!

.Net Fiddle https://dotnetfiddle.net/ is an option. Not exactly an interactive environment where you can try out any expression. In .Net Fiddle, you can change the project type, compiler version, etc.

LINQPad is very good, but if you are into a quick (no installation) C# snippet testing without external dependencies (files, databases etc.) you can also use Rextester.

However, notice that its compiler version is 4.0.30319.17929, so fancy things from C# 6.0 like interpolated strings, null conditional, property initializers will not be available.

It is called snippetcompiler, will search for the url...
