This article attempts to list the most important resources for using and learning about Windows Server AppFabric.
If you have a link that will help others learn about AppFabric, please edit this post and add it directly. Just keep it at a high-level. For example, I link to the MSDN content on Caching Features below, but I do not add noise by linking to each topic on caching.
Note that these links can be to both Microsoft and Community content.
