I'm new to CSLA, and havebeen struggling with trying to set up Remoting. I've got a response from the server-side so am trying to get my BOs mobile. It looks like I have a serialization issue, but I'm really struggling to see how to move forward.
Could someone give me some pointers about what I should be looking for and to move forward on this. I'm on CSLA 3.01.
Thanks
Simon
Sorry about this but I'm going to have to paste in a stack trace.

Thanks but I've managed to sort this. I'm pretty new to the CSLA and was struggling to set everything up properly. I hadn't understood about authentication and my DB connection string wasn't correct.
I think one of the problems when you're new to this is that the error messages don't give any pointers to what the problem might be. Further, because my knowledge is pretty limited , it is difficult to know how to break the problem down.

For newbies, I always recommend setting up everything to run locally at first.
Once that works things like connection string errors won;t be an issue - since you will have fixed them already. Debug remoting issues becomes a search for a configuration problem, since your code works locally!
