On-demand loading of assemblies with Silverlight Navigation – Revisited for Silverlight 4 Beta
Continue reading →Way back in July, shortly after Silverlight 3 was released, I posted a technique that allowed you to use the Navigation framework in the SDK to load pages in dlls that would be downloaded as part of the navigation process.

Opening up Silverlight 4 Navigation: Authentication/Authorization in an INavigationContentLoader
Continue reading →Continuing my series of posts on ways to use INavigationContentLoader (a feature in the Silverlight 4 Beta SDK), in this post, I’ll explore another idea for a composable INavigationContentLoader that protects access to your pages based upon the credentials of the user of your Silverlight application. To demonstrate its use, I’m using a WCF RIA Services application (purely for their Authentication/Authorization provisions).
