AppFabric was a great technology but it looks like Microsoft is decided to commit to open source Redis instead of keep investing on it:
Microsoft AppFabric 1.1 for Windows Server will end Microsoft Support one year from today’s announcement, which dates April 2, 2016
What can you do?
We recommend all Microsoft AppFabric customers using Cache to move to Microsoft Azure Redis Cache.
For those who require on premise caching solution, Redis on Windows is available from MSOpen Tech
And they also recommend NCache
