Today I completed a webcast as part of a 15 part series - today's subject concurrency, throughput and throttling. I received some questions about callback and Windows client applications that I thought I would elaborate on on my main blog. The post discusses the behavior of services and clients when you have a Windows client, a service with a callback contract (thus, two-way communication) and various WCF settings at the client and service that relate to concurrency, multithreading, synchronization with the UI thread, and so on.

You can get to the post here.

I have just posted the VB.NET lab code for my book. Remaining samples to follow. See this post for new details:

I have at long last finished the final edits on my WCF book! Whew!

Now, you can get early access to the entire book online at O'Reilly here:

In addition, I have posted the code for the book, with instructions to set up examples, here:

As for this book blog, I will be using it to post errata, updates and more importantly to provide samples and discussions to further what is covered in the book. I hope you enjoy!

Updated: 08/08/2007 - added VB.NET lab code

Updated: 11/13/2007 - added C# code converted to VS 2008 compatible solutions) 

You can get all of the labs and code samples for my book from this blog post. If there are any updates to the zip files, I'll post an entry to let you know. The first two links are for the labs and code in C# and VB.NET. The second link is for media files (very large) to support streaming samples in either language.

A very special thanks to Peter Young, one of my most throrough reviewers, who was commissioned to convert all labs and samples to VB.NET as he reviewed the book with great attention to detail. 

For help setting up you'll need Appendix A of my book, you can get that here:
