WCF Service with arcobjects not working after publishing

[BernardNtiamoah]

Hi guys,
Here is my problem: I have a very basic wcf service that returns information about a feature class in my silverlight application. Everything works great in the localhost but doesn't work after publishing the application to my server. It just keeps running without throwing any error or timing out. The funny thing is that if i remove all arcobject stuff from the service code, then it works fine. Am I missing something? here is my code.

                ESRI.ArcGIS.RuntimeManager.Bind(ESRI.ArcGIS.ProductCode.Server);

                //Initialize ESRI license
                ESRI.ArcGIS.esriSystem.IAoInitialize aoIinitialize = new ESRI.ArcGIS.esriSystem.AoInitialize();
                if (aoIinitialize.Initialize(esriLicenseProductCode.esriLicenseProductCodeArcServer) == esriLicenseStatus.esriLicenseAvailable)
                {
                    aoIinitialize.Initialize(esriLicenseProductCode.esriLicenseProductCodeArcServer);
                }

                IPropertySet propertySet = new PropertySet();

                propertySet.SetProperty("SERVER", "**");
                propertySet.SetProperty("INSTANCE", "***");
                propertySet.SetProperty("DATABASE", "***");
                propertySet.SetProperty("USER", "***");
                propertySet.SetProperty("PASSWORD", "****");
                propertySet.SetProperty("VERSION", "***");

                Type factoryType = Type.GetTypeFromProgID("esriDataSourcesGDB.SdeWorkspaceFactory");
                IWorkspaceFactory workspaceFactory = (IWorkspaceFactory)Activator.CreateInstance(factoryType);

                //Establish the connection with the database server
                IWorkspace workspace = workspaceFactory.Open(propertySet, 0);

                //Convert the workspace to feature workspace
                IFeatureWorkspace featureWorkspace = (IFeatureWorkspace)workspace;

                //Open feature class in the database
                featureClass = featureWorkspace.OpenFeatureClass(FCName);

hi Roy,
Add this in the beginning of your code

ESRI.ArcGIS.RuntimeManager.Bind(ESRI.ArcGIS.ProductCode.Server);

if the problem persists, right click on the your project =>properties =>Build tab =>change platform target to x86 instead of Any CPU.
