This is from a Jet brains employee posted on their forum
"Yes, we are working on a tool for .NET. As a first step we plan to release it as a plugin for Visual Studio. Later we plan to provide a full IDE. It's likely that we'll release the plugin on summer 2004 and EAP versions may be available very soon (in a month or so). " Posted: Nov 5, 2003 3:26 PM
The EAP version should be made available at www.intellij.net I would think since the EAP version of the java IDE is there.
