Anders Hejlsberg's C# 4.0 REPL

Question

During the last 10 minutes of Ander\'s talk The Future of C# he demonstrates a really cool C# Read-Eval-Print loop which would be a tremendous help in learning the language.

Answer 1

From time to time I want to try out some .NET API instead of wondering about C# language syntax. (There are far more subtleties in API than in the language itself.) If you are only looking for REPL for .NET, good old PowerShell is always with you.

C#:

using System;
using System.Text;

Convert.ToBase64String(Encoding.UTF8.GetBytes("Overflow"));

PowerShell:

[Convert]::ToBase64String([Text.Encoding]::UTF8.GetBytes("Overflow"))
