Works on the DevFabric should WORK in the Cloud....
Glenn Maughan commented
don't need a lightweight dev simulation. I'd like the DevFabric to simulate the VM and firewall. This woould reduce errors where DLLs are referenced but not Copy Local, certificates are incorrect, ports in use and help to get diagnostic config correct before moving to the cloud.
In .NET framework 4 most of the "standard" configuration was moved to machine.config. Azure OS does not have them in machine.config. I run into annoying problem with web role getting stuck to busy in cloud and the cause was the web.config not referencing all the needed sections even though it was running happily on dev fabric.

What is the list of devfabric/cloud fidelity issues that you run into? There is a trade-off in terms of providing the fidelity on the desktop and having a light weight development simulation and we want to find the sweet spot.

Indeed, got hit by a few problems here. In particular, DevFabric does not seems to exactly reproduce the Azure Medium Trust (I had to deploy once, hit the problem, enable full trust and redeploy).
