SharpDevelop 4.0 Released!

Prototyping of SharpDevelop 4.0 started on 5th of August 2008, with first screenshots released even before they shipped SharpDevelop 3.0. The prototype was ported to .NET 4.0 when its Beta 1 was released, and their team shipped a Beta 1 Preview when .NET 4.0 RC became available. The team went through four Beta releases and two release candidates before hitting their release milestone.

Major architectural changes from 3.x to 4.0:

  • The frame (workbench) has been rewritten to use Windows Presentation Foundation (WPF) instead of Windows Forms. We did not rewrite existing addins to be WPF-only, but many will switch over the course of time.
  • The text editor is also completely rewritten – from Windows Forms to WPF. The new text editor is called AvalonEdit, and like its Winforms predecessor, it is rehostable in your applications. Articles on that as well as its architecture can be found at
