Sharp Develop - A C# IDE

Dont know if this is well known IDE but just in case not:

#develop (short for SharpDevelop) is a free IDE for C#, VB.NET and Boo projects on Microsoft's .NET platform. It is open-source, and you can download both sourcecode and executables from this site. In addition, you can find the latest information and changes on #develop, as well as get in touch with the team in the forum.

i just had a quick look into it two days ago because i wanted to experiment with boo a bit. it seems to be very nice and not as bloated as visual studio.

Exactly.

I've used it too, I can recommend it !
