Description:

Advance your .NET expertise—learning proven techniques for building large-scale distributed solutions.

Make the jump to distributed application programming using the .NET Framework—and introduce a new level of performance, scalability, and security to your network and enterprise applications. Expert .NET developer Matthew MacDonald shares proven techniques for fully exploiting .NET Remoting, XML Web services, and other .NET technologies and integrating them into your real-world solutions. MacDonald digs into key .NET building blocks and architectural issues, explaining which features and designs will best serve your customized distributed application projects—and when to use them. Case studies with full code examples illustrate these practical techniques in action, as well as demonstrating their benefits and tradeoffs.

Learn how to:

• Cross application boundaries with .NET Remoting, XML Web services, and Message Queuing
• Create responsive clients and scalable servers with multithreading
• Model your distributed application with interfaces, facades, and factories
• Use COM+ services such as object pooling, JIT activation, and transactions
• Craft a data transfer plan with Microsoft ADO.NET?without concurrency errors
• Help secure your code end to end?from the transport level to the presentation tier
• Learn ways to avert?or unclog?performance bottlenecks in your applications
• Automate deployment using self-updating applications and XML Web services
• Master stateless programming and other best practices for distributed applications
