RuntimeManager.Bind Error migrating Engine app to 10.4.1

I am upgrading ArcEngine applications from 10.3 to 10.4.1 and am encountering an error when the RuntimeManager tries to bind to the product code.


I have revised the target framework for the application's projects to .net framework 4.5 and assigned the ESRI dll references to false regarding


The solution successfully builds, but when I try to run the application through Visual Studio I encounter the following error:


     "An unhandled exception of type 'System.MethodAccessException occcurred in ......exe


     Additional information: Attempt by security transparent method '...exe to access security critical method

     'ESRI.ArcGIS.RuntimeManager.Bind(ESRI.ArcGIS.ProductCode)' failed



I have included a screen shot of the error as an attachment


These Engine applications have been upgraded for numerous versions with out any grief regarding the RuntimeManager binding bit. I am assuming there is something related to the new framework target.



Any assistance would be greatly appreciated.
