Many software development communities have a very large thread in the forum about coding styles horror. Most of the posted code snippets are about exception handling, which shows how difficult this topic is. Therefore, we must talk about exception handling first, along with what to do and what not to do.
This part gives you an initial introduction to exception handling in Silverlight and a warm up for all developers who are familiar with this topic.
