Being only two days old there is little information out there at the time of this writing. By starting with Beta 1 configuration samples and working with Reflector to inspect the Microsoft.ApplicationServer.Caching.Core and Microsoft.ApplicationServer.Caching.Client assemblies I was able to make the necessary changes so that the configuration xml lines up with the associated configuration class. I ended up with the following.
Microsoft.ApplicationServer.Caching.Core, Version=220.127.116.11, Culture=neutral,
This minimalist configuration was enough to get me started with simple ‘Add’ and ‘Get’ operations against the cache.
var factory = new DataCacheFactory();
cache = factory.GetCache("default");
