I
Working with Visual Studio 2005 Standart Edition (Academic edition,
EN), and i got every time i want to create a new Class in the
classdesigner an "Failed to create class" error. Drag and Drop classes
from the Classview or Files form the Solution-Explorer works without
problems.
It was a clean Installation, no Beta2 install. Only
Windows XP SP2, Visual Studio Express C# German edition, .Net Framework
2.0 & 1.1 in german also both SDKs in German. I installed Visual
Studio without the MSDN Lib..
Visual Studio Version is 8.0.50727.42 (RTM.050727-4200);
.Net Framework version: 2.0.50727

Failed to Create Class Error

this happens if the languages of your windows installation and VisualStudio differ. Looks like you have an English version of VisualStudio, possibly running on a German version of Windows...
In VisualStudio, go to Options/Environment/International Seetings and switch the language from "Windows" to the language of your VisualStudio installation, restart VisualStudio and enjoy class modeling...
Thanks to Nicolai Stoy, who figured this out originally.

You need have VS2005 Standard edition or above to run class designer. Express is not a supported sku.
