So after moving to Vista last week, I've tried a full castle build with tests.

Things I had to take care for it to run properly (from easy to not-as):

1. Make sure Nant is in the path
2. Make sure that NUnit 2.2.x is in the path
   explanation: for some reason, the remoting tests fail when being run from NUnit 2.4.x   As I'd rather not to gac any specific NUnit version, I have on my C:\Program Files two separate directories, one called "NUnit 2.2.8" and one called "NUnit 2.4.7", and the shortcut I use for firing a Command Prompt for Castle is making sure that NUnit 2.2.8 is in the path.
3. Setup the test databases for DB related integration tests (as explained in "How To Build.txt")
4. Make sure that you use an elevated command prompt - the shortcut I've mentioned on 2. is set as "Run As Administrator"
5. To make the WcfIntegration facility tests run correctly, you need to run this thing once:
   sc.exe config NetTcpPortSharing start= demand
6. some config files are missing from the build folder (Castle\build). until we fix it in the nant script, you have to manually run
   copy ..\Facilities\Wcf\Castle.Facilities.WcfIntegration.Tests\Configure*.xml ..\Build

Now that I have a way to run the build and make sure all tests pass, I can start working on my next Castle assignment - bringing AspView into the core project, but that's a whole other post so keep your RSS reader open ...
