A couple of days back at Mix we announced the CTP release of the OData Client Library for Windows Phone 7 series.
Cool stuff undoubtedly.
But how do you use it?
Well Phani, a Data Services team member, shows you how on his blog.
Any word on when the next drop of the OData client for WP7 will be? I've found a few blocking issues that don't exist in the Silverlight 4 OData libraries that is preventing us from using the WP7 version. Thanks.
Same here. The LoadAsync is crashing all the time I give a more complex linq query to it.
Very bad so that I can't do any selection of data - only returning the complete feed is working,
Expression:.Where(o => (o.Mahlzeit = value(MyDietLogWP7.ModelHandler+<>c__DisplayClass0).mahlzeit))

Shalan007, that is exactly the issue I found as well. It pretty much makes OData unusable on WP7 right now. Note, hardcoding your filter works .Where(item => item.name == "hardcodedstring")
Of course how often does your data NOT reside in a variable!?
I found a workaround in case anyone cares: use CreateQuery and AddQueryOption instead. You end up with a bunch of ugly strings as opposed to nice clean, strongly-typed LINQ, but it works! Hopefully the OData team will release an update soon.
Hey I'm trying to connect SQL Azure on the Windows Phone 7 platform. I'm using DataServiceQuery to access my database on the cloud, but I cant find a way to update/add/delete my database using the same. Please help me out with sample codes! Thanks a lot.
