WCF Data Services/OData Code Sample - One app, one click, lots of samples....

Microsoft Developer Network - Samples - WCF Data Service (OData) Client Library One Click Code Samples

This code sample is intended to demonstrate most of the common operations (Such as CRUD,Batch Async Query etc) of WCF Data Service Client Library. Code sample are designed in one click falchion that means you can just double click and UI will take you directly in to Debugger (If attached) and then you can walk through the code step by step

One thing I thought a great source was the Debugger.Break feature. It's a little thing, but a really nice touch. Having that in a sample app like this makes a heck of allot of sense in hindsight...
