FYI, I ran into an issue while trying to Add Reference to a FEZ Domino project in Visual Studio 2010. I have Productivity Power Tools VS extension loaded. When I tried to add reference to GHIElectronics.NETMF.USBHost I was getting an incompatible library error and it wouldn’t let me add the assembly. It was complaining about .NET Micro Framework v4.1.2821.0 was not compatible with GHIElectronics v126.96.36.199. It was being very strict on the version number. This was using the Productivity Power Tools Searchable Add Reference Dialog.
To make it work I had to disable the Searchable Add Ref Dialog feature of Power Tools. Now I can add the references because it is using only major.minor version to determine compatibility. I’m going to send a bug report to Microsoft for this. I just wanted to let people know about this issue if someone else is having the same problem.
