MOSS Object Guids – Case Matters

Learned something today – the hard way.

In my deployment utility (which is a glorified way of simply deploying a solution by using the MOSS API), when I do an upgrade, I get the existing solution by ID via GetSolutionByID(string id) so that I can use the SPSolution object to perform the necessary actions.

However, in the middle of deployment, to my surprise, MOSS started yelling back at me, saying “Can’t find solution with ID <solutionID>”, but then declares “A solution with the name <SolutionName> already exists”.

It appears that MOSS cares whether or not the ID you pass into GetSolutionByID() is lowercase. Otherwise, MOSS won’t find the solution. I would have thought that this would be case insensitive, but it is apparently not.
