I too had this issue after two days of hair pulling, i noticed that the system.activities dll had a modified date which was close to the time/date from which i got this error and around that time we had a power outage, so i copied the same dll from another machine and pasted it there and it worked like a charm. For those who are interested the problematic dll is located in C:\WINDOWS\Microsoft.NET\assembly\GAC_MSIL\System.Activities\v4.0_4.0.0.0__31bf3856ad364e35 i dont know if whoever reads this has the same root cause as me......but its worth a try.
