I'm back into Silverlight
3 now after a long break. Since VS2010 RC was just released, I decided to upgrade my existing SL3 project and enjoy the benefits of a greatly improved IDE. The project appeared to convert to just fine, but I had compile errors. It seems my ObservableCollections were now arrays. When attempting to update/configure a service reference, it chooses ( Custom ) and ObservableCollection is no longer a choice!
Somebody goofed at Microsoft and left out the ObservableCollection type. To fix, you need to do this:
1. Choose System.Collections.ObjectModel.Collection as the Collection type (instead of ( Custom )).
2. Update, or configure your reference
3. Find the reference.cs (or .vb) file (open windows explorer and find it in your Services References folder)
4. Change all System.Collections.ObjectModel.Collection to System.Collections.ObjectModel.ObservableCollection.
Back in business. I have no doubt they'll fix this by RTM, but that allows me to work with the RC and Silverlight/WCF.
I hope this helps somebody. Happy programming.
