I was able to reproduce your problem. You are missing the reference to LockheedMartin.Prepar3D.SimConnect

missing the reference you wouldn't be able to compile.

my guess: you are compiling your assembly for "Any CPU". This cannot work for the SimConnect managed .dll, as it is x64 only. So, change the processor target to x64 and you should be good to go.
