Anyone who reads this blog will know that I am a supporter of open source & open standards etc. In this light I'd like to mention SharpDevelop from the guys at ic#code. Once again my learned friend, Phil Armitage, first introduced me to SharpDevelop a couple of years ago.

This is a very useful open-source IDE that you can use to code C# to your heart's content. It is very easy to use (has a similar feel to VS.NET) and does most things that VS.NET can do. In fact, I think Microsoft "lent" some of their ideas (XML Schema integration) for VS.NET '05 from SharpDevelop. It also integrates very well with nUnit, nAnt (and therefore CI in general). Obviously any code you write with SharpDevelop can be consumed by any .NET application.

SharpDevelop's one big con is that it doesn't ccurrently support Web applications yet. Definitely worth a look. They also have some insightful videos on their wiki.
