As I was building some new customer FIM 2010 workflows for a customer, I ran into that little annoying feature called Blocked File Protection Control.
I had created my initial Workflow Activity Library for FIM and references the FIM binaries to get access to the FIM activities. As I build my project I received a compiler error saying "Compilation failed. Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information."; this had me for several hours.
It turned out that since I had copied the FIM binaries from the FIM server to the Windows 7 developer computer, the OS had detected these files as potential "harmful" (FIM 2010 harmful :-) ?) and blocked these files. The error message that I got from the compiler was very helpful, so it actually took me a few hours to realize what was going on. After unblocking the DLL's I was able to compile.
If you run into this problem, check if the DLL's are blocked; in Explorer, goto Properties on the file and check the general tab for the text "This file came from another computer and might be blocked to help protect this computer".

There also is Unblock-File (http://technet.microsoft.com/en-us/library/hh849924.aspx) in PowerShell 3 and higher that does that.
