Just upgraded to CC.NET 1.3. And it didn't work. It spectacularly didn't work. Ok, it just didn't work:
Configuration Error
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.
Parser Error Message: The format of the file 'ThoughtWorks.CruiseControl.WebDashboard' is invalid.
Unfortunate, that. After a few fruitless web searches, I re-installed 1.2, and of course, that worked. Which gave me an idea...
Loaded 1.3 again, checked InetInfo settings, and sure 'nuff - it was still set to the 1.1 framework (1.3 is the first .NET 2.0 version of CC.NET). Change it to 2.0, and all was right with the world.
Thanks so much for that tip!
I'm not sure how long it would've taken me to figure out that it was pointing to the wrong version of the .NET framework in the ASP.NET configuration in IIS.
