[OpenBridge Modeler 10.09 C#] ManagedSDKExample error when loading into OBM

I've compiled the OBM ManagedSDKExample successfully. When I try to load the dll I get the following error message:

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** Exception Text **************
System.IO.FileLoadException: A procedure imported by 'Bentley.ObmNET.GeometryModel.NetSDK.dll' could not be loaded.
File name: 'Bentley.ObmNET.GeometryModel.NetSDK.dll'
at ManagedSDKExample.ManagedSDKExample.Run(String[] commandLine)
at Bentley.MstnPlatformNET.AddIn.Load(String[] commandTail, IntPtr mdlDesc)

Any idea where to start to find the issue?
