Metro OData prerelease bits and app

DB BlogsApril 26, 2012Apr 26, 201204/26/12

Phani just published a blog post with directions on how to build OData apps for Windows 8 Metro. The Metro bits are still very much in a prerelease form (e.g., you’ll have to invoke codegen with a command line tool) but it should enable developers to start trying out OData on Metro. For the blog post as well as sample bits and the sample app

JSON Light Sample Payloads

DB BlogsApril 17, 2012Apr 17, 201204/17/12

We recently put together a document that contains some of our thinking about JSON light as well as a whole slew of sample payloads. We would love to hear any feedback you have on the format; you can comment in the accompanying OneNote. We will be accepting public feedback on JSON light until May 4, 2012.

How to use WCF DS 5.0 in a Web Site project

DB BlogsApril 17, 2012Apr 17, 201204/17/12

The WCF Data Services 5.0 RTM release includes an update to the Add Service Reference behavior in Visual Studio. For most project types that target .NET Framework 4.0, this means that when you add a new service reference, you will automatically get assembly references to the new client assemblies, and your client will be able to communicate wi

Actions in WCF Data Services – Part 3: A sample provider for the Entity Framework

DB BlogsApril 12, 2012Apr 12, 201204/12/12

This post is the last in a series on Actions in WCF Data Services. The series was started with an example experience for defining actions (Part 1) and how IDataServiceActionProvider works (Part 2). In this post we’ll go ahead and walk through a sample action provider implementation that delivers the experience outlined in part 1 for the

What happened to application/json in WCF DS 5.0?

DB BlogsApril 11, 2012Apr 11, 201204/11/12

The roadmap for serialization formats We have been talking for a while about a more efficient format for JSON serialization. The new serialization format will be part of the OData v3 protocol, and we believe that the much-improved JSON format should be the default response when requesting application/json. You may notice that when you upgrad

Actions in WCF Data Services – Part 2: How IDataServiceActionProvider works

DB BlogsApril 11, 2012Apr 11, 201204/11/12

In this post we will explorer the IDataServiceActionProvider interface, which must be implemented to add Actions to a WCF Data Service. However if you are simply creating an OData Service and you can find an implementation of IDataServiceActionProvider that works for you (I’ll post sample code with Part 3) then you can probably skip this

Actions in WCF Data Services – Part 1: Service Author Code

DB BlogsApril 10, 2012Apr 10, 201204/10/12

If you read our last post on Actions you’ll know that Actions are now in both OData and WCF Data Services and that they are cool: “Actions will provide a way to inject behaviors into an otherwise data-centric model without confusing the data aspects of the model, while still staying true to the resource oriented underpinnings of OD
