The MVP Summit this year takes place at Bellevue and Redmond on February 28 – March 2 and as an MVP I decided to come by this time. It will be my first time there and I’ve only heard how cool it is, so I’m eagerly waiting to see it myself.

During that period there will be also a Seattle Silverlight UG meeting.

This video is the first in a series dealing with WP7 and starts by showing you how to get a project that talks to a web service (via WCF Data Services) set up and running.

I have decided to take my Silverlight MVVM Golf Handicap application and build it with WP7. This first tutorial just gets things set up and displays the courses stored in the database. Subsequent tutorials will add functionality to the application with the goal of creating a WP7 application with all the functionality of the Silverlight version.

I spent quite a lot of time with WCF Data Services (‘Astoria’/’ADO.NET Data Services’ as it was) in its first iteration.

It’s a framework that I really like so I’m feeling a little guilty that I haven’t found time to completely revisit it as it becomes part of a ‘much bigger thing’ (i.e. OData) and as it got rev’d in .NET 4.0 and (from a client perspective) Silverlight 4.

The three options for data access are still the same "Web Services, WCF Data Services and WCF RIA Services". My major issue with data access today in Silverlight persists: there is no perfect answer. There is give and take with each approach and giving good advice about the right one is difficult.

The simplest way to expose your data as OData is by using the WCF Data Services, which currently comes with a couple of out of the box providers (EF, Reflection etc…). Each provider requires it’s own data model and if you have made XPO your ORM of choice, switching to another model is out of the question. Adding an additional data layer is not something you would want to do either, maintaining more than one is rarely a good practice.

1. Introduction

In my previous article about WCF Data Services I showed you how to get a full control under the proxy generation process using T4 templates. But to tell you the truth, I don’t like code generation in all of its forms. Today I am going to show you how to use WCF Data Services without code generation at all.

1. Introduction

This is the first article of my series about deep dive into  WCF Data Services. In this article I'm going to show you how to implement your own WCF Data Services proxy with T4 templates.

2.1 Problem

WCF Data Services is a very powerful toy, but as many other cool Microsoft technologies it needs some workarounds to become usable in the real world applications.

Most of the problems are connected with the auto generated proxy which is created after the addition of a service reference.
