how to configure Application Server extension for app fabric

I am looking for dlls , which I read on google is in C:\Windows\System32\Application Server extension . I cannot see this folder on the machine where appfabric is installed.

CacheBaseLibrary.dll ClientLibrary.dll 开发者_运维知识库FabricCommon.dll

Any ideas, how to get this folder?

I'm guessing you're on a 64-bit Windows installation? If so, you will find the assemblies under the following location:

C:\Windows\SysNative\AppFabric

You can read about this in the MSDN section titled: Preparing the Cache Client Development Environment (Windows Server AppFabric Caching)

Those DLLs were used in the beta versions of AppFabric, when it was codenamed Velocity. In the release version of AppFabric they have been replaced by
Microsoft.ApplicationServer.Caching.Core.dll
Microsoft.ApplicationServer.Caching.Client.dll

You should find these in %SYSTEMDRIVE%\System32\AppFabric, or follow Drew's answer if you're on 64-bit.
