Windows Azure Web-Role Caching (Preview) "hangs" makes the emulator stuck in deploy loop

I'm trying to replace the Windows Azure AppFabric Cache with the newly released Role-based caching that was introduced in the June 2012 SDK release by following the guides on Microsoft's website.

However, when checking the "Enable Caching (Preview)" in my Web Role, the emulator will not successfully instantiate the web site (emulator log: http://pastebin.com/dwbDvak2). It seems it is getting stuck in some kind of loop. Disabling the Web Role caching makes it work again. I have gotten the same result after uninstalling all previous Azure SDKs and re-installed the 1.7 version.

Visual Studio is telling me that "Role instances are taking longer than expected to start. Do you want to continue waiting?" [Yes][No]. Pressing Yes keeps it waiting, and shows up over and over again.

Are there anyone who might know how to solve the issue described above, or perhaps have tried the new web role caching functionality and got it working in the azure emulator?

Thank you.

Update:

I created a new solution, and added just a simple MVC site, added the web role and enabled caching, and the same thing happened. So, I took a look at the Event Viewer, and found 3 entries relating to the issue:

For me, the problem was that I was running my project off of a UNC Share (actually its running in a VM on my macbook). When I'd start the debugger after checking the "Enable Caching" box on the worker role, it would just hang. Come to find out, about every 2 seconds it was creating a 160MB dump file in C:\Windows\System32\%LOCALAPPDATA%\CrashDumps. After debugging one of those, I could see the first error was when it tried to start cmd.exe on the caching stuff in my worker role and it said CMD cannot be run on a network share, so it would default to windows/system32 or something.

That's when I found this handy dandy 7 year old MS KB article: http://support.microsoft.com/kb/156276 When I added DisableUNCCheck REG_DWORD and set the value to 0 x 1 (Hex) under the registry path HKEY_CURRENT_USER\Software\Microsoft\Command Processor everything started up just like a champ. Hopefully this helps someone else.

Do you mean as long as you check the CheckBox to enable caching, this error occurs? This should not happen... It works fine on my machine.

Are you creating a new project or upgrading an existing project? Try to create a new project.

Also check the following logs:

I had the same issue. To do with an AppFabric Server dll conflict - check whether you have AppFabric Server installed and either deinstall the cache or remove the cache assemblies from the GAC. I removed and the emulated cache works fine.

I have some information which may be helpful on our blog:

Missing method probably means that the assembly loaded doesn't have the method in there. Can you make sure that you've the proper assembly being added to your project ?

Ensure that you don't have Windows AppFabric Server installed in the machine as well, as it'll GAC the caching dll which will get picked up during runtime
