I opened the solution in VS2010. The conversion was done without errors. I changed all 3.5 references to 4.0. Had to adjust the configPages entry in the web.config. Changed the properties of each project to deploy for 4.0. Added the database (RapidWebDev),
run the scripts. Changed the connectionstring in web.config.
I was able to compile the solution.
When I start the web app in debug mode, an error occurs in installerManager.cs. There is no entry in the aspnetApplications table. Should there be one? How does it get filled?
When I try to use the MS stuff that allows one to add users and groups to a webite, there is an error in some SPRING module.
Folllowing the quick setup script from your website gives the same problems. Trying to run the unit tests gives an error on the signature of the dll.
