I'm trying to use a DifferenceCursor on a utility network feature service geodatabase. I am following the guide here I am able to use the VersionManager class to open the default geodatabase and the version geodatabase and then open the same feature class from both of them. However, when I try to create a DifferenceCursor I get this error "Object has no schema locks". I dug into this a bit further via the VersionManagerServer rest endpoints. If you go to https://<server_url>/rest/services/<feature_server>/VersionManagementServer/versions/<version_guid>/differences and try to run it you get the same error: This can be overcome by running the startReading command  Then you can go back to the differences endpoint, put the same sessionId in and it works. It doesn't look like VersionManager does this first step of starting a read session. Here's a snippet of the code I'm using. ServiceConnectionProperties serviceConnectionProperties = new ServiceConnectionProperties(new Uri(config.Connection.UtilityServiceUri)); using (Geodatabase gdb = new Geodatabase(serviceConnectionProperties)) using (VersionManager versionManager = gdb.GetVersionManager()) { //here's where I was going to try calling the startReading operation directly off the ReST endpoint WebClient versionManagerClient = new WebClient() { BaseAddress = config.Connection.UtilityServiceUri + "/VersionManagementServer" }; Version navigateVersion = versionManager.GetVersions().First(v => v.GetName() == config.ApplicationConfiguration.NavigateVersion); using (Geodatabase navigateGdb = navigateVersion.Connect()) { foreach (string featureClass in config.FeatureClasses) { //service feature classes have the layer number prefix i.e L0PipelineLine //so we use this function to translate between human readable and the actual layer name FeatureClassDefinition serviceFCDefinition = GetServiceFeatureClassName(featureClass); string serviceFeatureClassName = serviceFCDefinition.GetName(); FeatureClass defaultFc = gdb.OpenDataset<FeatureClass>(serviceFeatureClassName); FeatureClass navigateFc = navigateGdb.OpenDataset<FeatureClass>(serviceFeatureClassName); //this line gives me "Object has no schema locks" DifferenceCursor diffCursor = navigateFc.Differences(defaultFc, DifferenceType.Insert); while (diffCursor.MoveNext()) { using (Row row = diffCursor.Current) { log.Append(String.Format("Post Change: insert into geometry_changes ({0}) values()", String.Join(", ", outputFields))); } } } } }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...
