Setting things up on Windows
From OpenSimulator
1. Get and build the code
Much instruction on this is in the User Docs
2. Start programming
Okay, so you'll want an IDE. There are two choices on Windows, SharpDevelop or Visual C# 2008 (2005 would also be fine). Get one of these babies, and then load in the OpenSim.sln (as generated by prebuild.bat described in the user instructions).
