Andy guides you through one way of implenting repository pattern using Entity Framework 4. The repository pattern can assist in building application logic that can take advantage of an ORM without being coupled to it. The Repository pattern has great appeal when it comes to unit testing, as stubing out a repository is trival.

Richard looks at using a custom message filter to plug complex routing logic into the WCF 4.0 Routing Service. He uses the example of a round robin load balancer that allows you to take endpoints offline without changing the routing configuration

Richard looks at plugging your own routing logic into the WCF 4.0 Routing Service using a custom message filter

Richard continues his exploration a new feature of WCF 4.0 called the routing service and shows how to achieve data dependent routing (sending the message to different places based on data in or about the message) using the routing service

Richard continues his exploration a new feature of WCF 4.0 called the routing service and shows how it can be used provide multicast and failover to services without changing the client

Richard introduces a new feature of WCF 4.0 called the routing service and shows how it can be used to bridge different network protocols

Andy introduces a Parallel Pattern called Geometric Decomposition utilising .NET 4 parallel framework. In this screen cast he will show how an array can be broken down into a series of smaller data pieces having many identical tasks running in parallel work on their own specific piece of the data. Whilst there are scenarios were each task can run in isolation its often found that these various tasks need to co-operate around the edges of their specific pieces. Andy will demonstrate two ways of solving this problem. One utilising pure Parallel.ForEach and another utilising the new Barrier type.

Andy continues his tour of the .NET 4 task API demonstrating how the new ContinueWith method makes it even easier to martial updates back on to the UI thread.

Richard shows you how to work with large messages using WCF's built in streaming functionality.
