Videos
ADO.NET Data Services - Surfacing Data ADO.NET Data Services let us make data widely available through RESTful web services. In this video we take a look at how we can offer data from the ADO.NET Entity Framework, LINQ to SQL and any arbitrary data.

ADO.NET Data Services - Querying with URI's ADO.NET Data Services offers data over RESTful web services - in this video we look at how we can build URI's to represent the different server-side resources that we want to access.

ADO.NET Data Services - A Basic AJAX Client In this video we'll take a quick look at building a basic, read-only AJAX client for an ADO.NET Data Service.

ADO.NET Data Services - A Basic Silverlight Client In this video we'll use the "ASP.NET Data Services Silverlight Add-On" in order to build a simple read-only Silverlight client for an ADO.NET Data Service.

ADO.NET Data Services - A Basic .NET Client In this video we'll take a quick look at how we can build a simple, read-only .NET client against an ADO.NET data service and how we can continue to use the URI-based query mechanism to get data from that service.

ADO.NET Data Services - Querying with LINQ For a .NET client that interacts with an ADO.NET Data Service, we can use LINQ in order to construct the query on the client side. We construct a query using LINQ and the client-side framework translates that into a URI for us. In this video, we take a quick look

ADO.NET Data Services - Query Interceptors ADO.NET Data Services has a facility whereby we can plug-in code to run whenever a query for a particular entity set is executed. In this video, we take a look at how we can write these Query Interceptors.

ADO.NET Data Services - Service Operations ADO.NET Data Services has a service-side facility for adding pre-built operations ("Service Operations") which can run arbitrary logic which can additionally be parameterised using simple serialised types from the URI. In this video, we take a look at building such Service Operations.

You can find multiple videos on MVC, Dynamic Data, AJAX, and the Entity Designer on the bottom of this page, and more on this page.
