A quick shout out is in order to Oleg Shilo.  The CS-script is fantastic for basic scripting needs or testing behaviors of C# and .NET.  Oleg has also included a plugin for Notepad++.

It also can be used to generate executable “scripts” to make useful utilities without bringing up an entire development environment and the overhead of projects and solutions.

For me personally, it will never really replace Python but it is good to know that there are alternatives for Windows based development when Python is not an option.  (Yes, those times do actually exist for some of us.)

More poo in the toolbox.
