With the release of .NET 2.0 you can now go and download the final version of MSBuild. We are included in the .NET 2.0 Redistributable. Of course, if you have an MSDN subscription you can go and download Visual Studio 2005, and we show up in that download as well. The .NET 2.0 download is a bit smaller, though *grin*.
