This how you fix the problem. Check to see if you have any problem implementing any interface class relative to the COM object involved here. You'll have an error such as the following:
Interop type 'ESRI.ArcGIS.Display.SimpleLineSymbolClass' cannot be embedded...
In this case open the Properties window for the ESRI.ArcGIS.Display reference and set the value of the Embed Interop Types to False.
It fixed the error.
