Igor Ostrovsky found that some browser features do not extend into Silverlight apps and decided to go over the affected browser features one by one, and discuss ways of getting them working.
Silverlight 2 is an awesome platform for development of rich web applications. One issue to be aware of, though, is that some browser features do not extend into Silverlight apps. For example, the Back and Forward browser buttons do not always work as the user may expect with Silverlight apps. The set of browser features you’ll miss in Silverlight apps is pretty much identical to what you’d miss in Flash or AJAX, and some of them are about to be addressed in the Silverlight 3 release.
