Question

I’m having some trouble using Windows Azure Cache Preview.

I’ve add the Nuget Package here: http://nuget.org/packages/Microsoft.WindowsAzure.Caching and have configured my role for storing the ASP.NET sessions state as per the info on windowsazure.com

Problem is, I get No connection could be made because the target machine actively refused it 127.255.0.0:20004 when debugging. The dev IP used by Azure is 12.7.0.0.1:81

I’m not sure why, even the sample Windows Azure Caching (Preview) Session State and Output Caching Sample does the exact same thing.

Update: error from log:

w3wp.exe Error: 0 : ERROR: <SimpleSendReceiveModule> b4551065-941b-4bdb-9487-57d9207af308:Request - 1, result - Status=ChannelOpenFailed[System.Net.Sockets.SocketException (0x80004005): No connection could be made because the target machine actively refused it 127.255.0.0:20004
   at Microsoft.ApplicationServer.Caching.AsyncResultNoResult.EndInvoke()
   at Microsoft.ApplicationServer.Caching.TcpClientChannel.ConnectionCallback(IAsyncResult result)] for end point [net.tcp://127.255.0.0:20004]

Also, more testing shows it is just not for session state storage, but all cache related tasks.
