As mentioned by Mustansir and Neha, you will not find AppFabric Template in Visual Studio Project Template list after the installation of the exes from the new CTP link you provided. Rather you will find ServiceBus Template from where you can create EAI/EDI
Do you have a previous version of CTP installed in your machine? If yes, please uninstall the previous version and install the new CTP version from the product download link you mentioned.
After installing, if you check under Control Panel -> Programs -> Programs and Features, you should see an entry for "Windows Azure ServiceBus EAI & EDI Labs SDK - April 2010" with version "2.0.846.0".
Once you have this installed, kindly open your Visual Studio 2010 and you will find the Project Template of ServiceBus under Visual C# Template from where you can select either EAI/EDI Project.
