AppFabric Cache not working on azure after upgrading to V2.0 of azure SDK

[rgupta77]

NHibernate.Caches.Appfabric nuget package for using Azure AppFabric Caching service as the second level cache for NHibernate was working fine with V 1.8 of the Azure SDK.

However after upgrading to VS 2012 and version 2.0 of the Azure SDK the nuget package has stopped working and the AppFabric DLL is unable to Establish Connection with the Azure AppFabric Caching service.
We get the following error when connecting to the Azure AppFabric Caching service:

Exception type: DataCacheException
Exception message: ErrorCode:SubStatus:There is a temporary failure. Please retry later. (One or more specified cache servers are unavailable, which could be caused by busy network or servers. For on-premises cache clusters, also verify the following conditions. Ensure that security permission has been granted for this client account, and check that the AppFabric Caching Service is allowed through the firewall on all cache hosts. Also the MaxBufferSize on the server must be greater than or equal to the serialized object size sent from the client.). Additional Information : The client was trying to communicate with the server: net.tcp://192.168.171.9:20005.

Can you please suggest how to resolve this issue??

Hi,

I'm sorry you are having problems. What have you tried to resolve this?

I have only ever tested this library with windows server app fabric
rather than azure although I have heard that (up until now) it has
worked fine. Are you aware of any breaking changes between v1.8 and v2.0
of the Azure SDK?

Thanks
Simon

I was relying on the NHibernate.Caches.AppFabric library to work with the Azure Caching Service. I have tried setting the channelOpenTimeout and requestTimeout attributes on the dataCacheClient element under dataCacheClients section in web.config, however this has not helped.

The dataCacheClients section for Azure AppFabric is a bit different from the Windows Server AppFabric version and looks as follows:
dataCacheClients
dataCacheClient name="default" channelOpenTimeout=3000 requestTimeout=5000
autoDiscover isEnabled="true" identifier="SCMProfitCache"
dataCacheClient
dataCacheClients

the default AppFabricProviderSettings look as follows:

AppFabricProviderSettings
CacheType="Named"
NamedCacheTypeRegionName="nhibernate"
NamedCachesMustExist="false" LockTimeout="30000" LocksRegionName="Locks"

I have tried changing these to use CacheType="Region" and reducing the LockTimeout value. However i was still unable to resolve the Estabilsh connection error.

The NHibernate.Caches.AppFabric library was working fine with the .Net Framework 4. however after migrating to VS 2012 and .Net Framework 4.5 the library does not work.

I dont know of any breaking changes between Azure SDK 1.8 and 2.0.
I have even tried upgrading to Azure SDK 2.1 (released on July 31st 2013) however the establish connection error still exists.

What happens if you just upgrade to .net 4.5 but stick with the older version of the SDK?
