To build NServiceBus just open NServiceBus.sln in Visual Studio.
Note that the debug build doesn't ilmerge and if you plan to use the binaries in test/production you need to do a release build.
You'll find the built assemblies in /binaries.
If you see the build failing, check that you haven't put the source of NServiceBus in a deep subdirectory since long path names (greater than 248 characters) aren't supported by MSBuild.
To run NServiceBus, please download and install the setup file from http://particular.net/downloads
