I am trying to use Windows Azure Caching to store sessions in a MVC4 application. I build a application following steps from Link but when i try to make object of DataCache using below code line.
DataCache cache = new DataCache("default");
Errors occurs:
Microsoft.WindowsAzure.ServiceRuntime.dll not found or version mismatched, I updated my Windows Azure Emulator version to 2.0.0 and install WindowsAzure.Caching package version 2.0.0.0 using NuGet package installer. Now the error changes to "The type initializer for 'Microsoft.WindowsAzure.ServiceRuntime.RoleEnvironment' threw an exception."
I am using Windows 8 with VS2012 and Windows Azure Emulator version 2.0.0.
I will grateful if anyone can help me on this.

I experienced this when migrating from Azure SDK 2.3 to SDK 2.4.
I noticed the migration automatically fixed all references to the service runtime for my web and worker roles, i.e.
C:\Program Files\Microsoft SDKs\Windows Azure\.NET SDK\v2.3\ref\Microsoft.WindowsAzure.ServiceRuntime.dll
changed to:
C:\Program Files\Microsoft SDKs\Azure\.NET SDK\v2.4\ref\Microsoft.WindowsAzure.ServiceRuntime.dll
However any assemblies referenced from the web/worker roles that referenced this assembly didn't update so I had to do it manually.
In addition I had to update the web.config and app.config entries to reference 2.4.0.0
