I ready Rocky's last post regarding MonoDroid.  I tried configuring the DataPortal for Remote use in code on but with no luck. So, I thought I would through this question out there. Has anyone had any success configuring the DataPortal for remote use in Monodroid?

I got the call to the remote DataPortal working. Now, it seems that the error is occurring someone in the framework on Deserialization. Can anybody help with this? this is the Soap message being set back to the client. I am working with Csla Version

Same issue here. I wonder if this is a serialization issue. Has anyone successfully built an app using CSLA and MonoDroid with client and remote dataportals? It seems to fail during deserialization.

It'd be interesting to see if the new serialization engine is the problem.  I haven't done anything with Monodroid but 4.2 I believe introduced the support for Monotouch/droid and 4.3 is what brought in the new serialization engine. 

It might be worth just trying your scenario with CSLA 4.2?

Using a remote data portal is unfortunately unsupported. Originally monodroid didn't have a supported WCF implementation. I think they do now, but Kevin (my monodroid dev) is buried in his day job and has no time to work on CSLA for the moment.
