Consume restful webservice with complex type in .NET from coldfusion

Question

I have problems in ColdFusion of how should I set the complex parameters that needs the restful NET webservice. Actually I have the next code but when I consume the Ws I have the message "Object reference not set to an instance of an object." So, I think my CF code is wrong.

<cfset dotnetstring = createObject(".net", "System.String", "dotNetCoreProxy.jar")>

<cfset ClienteList = CreateObject(".net","System.Collections.Generic.List`1", "dotNetCoreProxy.jar").init(dotnetstring.getDotNetClass())>
<cfset CoberturaList = CreateObject(".net","System.Collections.Generic.List`1", "dotNetCoreProxy.jar").init(dotnetstring .getDotNetClass())>
<cfset IncisoList = CreateObject(".net","System.Collections.Generic.List`1", "dotNetCoreProxy.jar").init(dotnetstring.getDotNetClass())>
<cfset ClausulaList = CreateObject(".net","System.Collections.Generic.List`1", "dotNetCoreProxy.jar").init(dotnetstring.getDotNetClass())>
<cfset CuotaList = CreateObject(".net","System.Collections.Generic.List`1", "dotNetCoreProxy.jar").init(dotnetstring.getDotNetClass())>
<cfset ObservacionList = CreateObject(".net","System.Collections.Generic.List`1", "dotNetCoreProxy.jar").init(dotnetstring.getDotNetClass())>

I have the sample of how consume the webservice from NET. My problem is how should I setting the objects in CF.

                                            };
        //Instantiate service as client

        IntegrationService.EmissionServiceClient myServiceClient = new IntegrationService.EmissionServiceClient();
        //Open service client request
        myServiceClient.Open();
        //Call specified WebMethod as necessary, sending Emission object as parameter
        result = myServiceClient.createPolicy(myEmission);
        //Close service client request
        myServiceClient.Close();

        Label1.Text = result;
    }

I hope is there someone can help me with any hint.

regards!
