I am using VS2010, AppFabric 1.1 and WF4/WCF. I have tried several samples including some that I downloaded from Microsoft. They work as long as I don't use AppFabric. Any attempt to host or configure through AppFabric fails with all kinds of errors.
AppFabric seems to place weired connection strings in the root web.config and during debug VS2010 can't find the connection strings. Unintstalling AppFabric leaves files that it has updated behind.
My question are "Are people using AppFabric ? Is it a pre-mature release or bad architecture ?"
The configure AppFabric UI leaves a lot to be desired also. This is supposed to run on production boxes using Windows 2008 R2 and its quality leaves a lot to be desired.
