[Podcast] Thread-Safe Asynchronous Smart Clients

Ask Udi Podcast – Udi Dahan – The Software Simplist

In this podcast we’ll look at various patterns involved in creating MVC-based Smart Clients which communicate using asynchronous messaging and how to avoid threading problems there.

Neil asks:

Hi Udi,

We’re building a smart client application that uses WCF for full-duplex communications with our server. This is the asynchronous communication you talk about in your podcast. The smart-client is based on the MVC pattern, where model objects raise events when they’re changed so that the views can update themselves.

What’s started happening recently is that the smart-client has been freezing-up on us intermittently. We don’t know how to debug this and are wondering if its an architectural problem.

Any help you can give would be most appreciated.

Neil
