Expert Distributed .NET
Duration:  4 Days
Description
With the release of .NET, Microsoft has again changed the distributed programming landscape. Everything from data access, to remote object calls, to web development has changed. In this class, you will learn how to build fast, flexible, and scalable middleware using Web services, .NET Remoting, and MSMQ. You will also learn how to interact with COM+ from managed code to take full advantage of services such as object pooling and distributed transactions.

Deployment is a fact of life with any distributed application. So this course also details the common deployment issues with .NET remoting and how to overcome them. It also shows how Web services and smart client technologies help ease your deployment burden. The class finishes with a preview of future .NET distributed technologies including an overview of Indigo and Service Oriented Architecture (SOA), and discusses the strategies you can employ today to prepare for these future technologies.

All code examples and labs are written in C#, but programmers using VB.NET or any .NET language are welcomed and can use their language of choice in class.
