NClass is an open source class diagram editor with fully customizable GUI.
It supports C# and Java languages with strict syntactical and semantical controlling.
It is entirely written in C# so this program requires the .NET Framework 2.0 to run.
This quick release fixes a lot of serious bugs that caused the program to crash.
Please note that this version is still an alpha version.
