thanks Michael, that is really helpful.

I found the one similar to yours "http://msdn.microsoft.com/en-us/wazplatformtrainingcourse_windowsphone7andthecloud_topic2#_Toc283646805"

I am making the windows phone 7 client for the native silverlight 4 application which runs on WCF service, and I used to entity framework and domain service for the data connection. When I created the service reference for the WP7, the domain service does not support to write back in current version.

Your example helps to write back from the WP7

Hey Dongol,

Make sure that the entity set is set to something like .AllWrite instead of .AllRead as shown below:

config.SetEntitySetAccessRule("Students", EntitySetRights.AllWrite);

This will permit all write access on Student entity set.

You can then use code similar to this screenshot: http://www.c-sharpcorner.com/UploadFile/dhananjaycoder/1619/Images/35.gif

or scroll down to the bottom of this article for more info: http://www.c-sharpcorner.com/UploadFile/dhananjaycoder/1619/

One thing to note is that right now you cannot use LINQ right now with the WP7 version. I have heard they are planning to release a fix for this at some point.

I hope this helps.

if I need to write back from the windows phone 7 client to the server, how would I do that. As I did some of the research, I learned that odata currently supports read only.

Hello Chaitanyarvk, OData is just the service and doesn't care what is accessing it (so it could be LinqPAD, a console application, silverlight, windows phone 7, etc). Now in order for Silverlight to consume the service, you would need to use a cross domain policy file in place on the target server. Here is a great writeup on it. I hope this helps.

Thanks for the second part, by the way does OData need Cross Domain Policy files?
