I’m making the slides available as well.
At the end of the webcast, a few questions came up that I mentioned I would try to provide some answers for on my blog.
Q: How to use ACS from a Silverlight application?
A: I haven’t personally tried this yet, but it seems others have. Here are a few resources I would recommend to learn more
Q: How to use ACS with Active Directory?
A: Have a look at the “Single Sign-On from Active Directory to a Windows Azure Application Whitepaper”.
* I wouldn’t necessarily recommend using the cache service outside of Windows Azure as the network latency (going over the internet) would likely reduce any benefit of caching.
