Disclaimer: I work for PreEmptive Solutions (the makers of Dotfuscator).

If you tried Dotfuscator a while back you should probably give it another try. We are constantly improving our XAML/BAML parsing & rewriting capabilities. You should be able to get a new free evaluation version easily from the PreEmptive website (or by contacting sales).

Most of our customers are able to obfuscate the majority of their WPF/Silverlight/WP7 applications without significant exclusions. Even if the BAML obfuscation breaks something in your application you should be able to selectively exclude only those items than should not be renamed.

If you do have a specific scenario of something that we break during obfuscation please go ahead and send it in, we're always looking to make our product better.

At this time the only other .NET obfuscator (that I know of) that claims to be able to modify XAML or BAML is CodeFort. I am obviously biased so I'll let you investigate the products and make your own judgment :)
