The Open Source Development Environment for .NET

#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.
We are going to add more content (and new releases) over the coming months, so sign up for our announcement list! Also, we want to invite you to participate in the forums, discussing SharpDevelop - its features, feature requests and of course bugs.
