SAP.net Connector using reflection C#

We are using SAP.net connector in C# windows service application, as per license documentation on SAP page, the libraries are not redistributable(sapnco.dll, sapnco_utils.dll), the customer needs to have its own licensed copy of the library, and we are using DirectoryCatalog(MefFunctions.GetPlugInDir()) to load all assemblies from plugin folder so over without physical copy of dll the windows service application does not work and it throws an error that the sap dlls are missing as we have added dll's as part of references, could you please help to overcome this problem, one thing I thought off is to use reflection instead of directly using the dll references in project, not sure how to do with references like inheriting the sap classes in our custom class, could you please help.
