|Data Points - LINQ Projection Queries and Alternatives in WCF Services
LINQ's ability to project randomly shaped data into anonymous types can be a blessing and a source of frustration, says Julie Lerman. It’s great when you just need to grab a special view of your data, but it can be problematic in certain circumstances. She explains what the limitations are and how to get around them.
|Foundations - Service Bus Buffers
Learn some advanced Windows Communication Foundation programming techniques as Juval Lowy begins an in-depth examination of the Windows Azure AppFabric service bus, focusing first on buffers.
|Now Playing - Building Custom Players with the Silverlight Media Framework
The Silverlight Media Framework is an extensible and scalable video framework upon which you can create your own player experiences. We’ll walk you through a custom player project that displays suggested videos for further viewing after the current video ends.
