I am using a SOE on top of a MapService in order to enable complex editing of the features in my File-Geodatabase. We use a SOE as we have much ArcObjects-code in our code-base that wraps rows from within a table to actual features. So in fact a feature consists of several rows in different tables, thus updates to a single row should be notified by the others. We´re also using topological edits which I suppose a feature-service can´t handle. When I try to edit a feature I get the following error: Workspace or data source is read only. If I understand things right, a map-service is just for presenting a map, not for modifying the data. This is where a feature-service would come into play, which however does not have support for a Server-object-extension and thus won´t handle our business-logic very well.  I´ve already tried to read the connection-properties of the underlying map-service and re-open it: public void Init ( IServerObjectHelper pSOH ) {      serverObjectHelper = pSOH ;      if ( serverObjectHelper . ServerObject . TypeName == "MapServer" )      {           m_mapServer = serverObjectHelper . ServerObject as IMapServer ;           m_mapServerDataAccess = ( IMapServerDataAccess ) serverObjectHelper . ServerObject ;      }      IMapServerInfo mapServerInfo = m_mapServer . GetServerInfo ( m_mapServer . MapName [ 0 ] ) ;      IMapLayerInfos mapLayerInfos = mapServerInfo . MapLayerInfos ;      for ( int layerId = 0 ; layerId < mapLayerInfos . Count ; layerId ++ )      {           IFeatureClass fc = ( IFeatureClass ) m_mapServerDataAccess . GetDataSource ( m_mapServer . MapName [ 0 ] , layerId ) ;           if ( fc != null )           {                IDataset fsDataset = ( IDataset ) fc ;                m_workspace = fsDataset . Workspace ;           }           if ( m_workspace != null )                break ;      }      if ( this . m_workspace == null )           throw new ArcGISAccessException ( "Workspace could not be opened" ) ;      var props = this . m_workspace . ConnectionProperties ;      var factory = new FileGDBWorkspaceFactory ( ) ;      var editWorkspace = factory . Open ( props , 0 ) ; } ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ However this yields to the examt same error. I can´t see what I´m doing different than the code from the samples. I also noticed that I am able to edit the data in the geodatabase in ArcMap without any problems, even when it is used by the map-service. EDIT: To limit the cause of error I set up a completely new service that references a newly created File-Geodatabase containing only a single feature within a featureclass ("FC"). Now I update that feature within my request-handler: private byte [ ] ModifyFeature ( NameValueCollection boundVariables , JsonObject operationInput , string outputFormat ,               string requestProperties , out string responseProperties ) {      responseProperties = null ;      var featureWorkspace = ( IFeatureWorkspace ) this . m_workspace ;      var editWorksopace = ( IWorkspaceEdit ) this . m_workspace ;                   var featureClass = featureWorkspace . OpenFeatureClass ( "FC" ) ;      var feature = featureClass . Search ( null , false ) . NextFeature ( ) ;      var index = featureClass . FindField ( "MyAttribute" ) ;      if ( featureClass . Fields . Field [ index ] . Editable )      {           editWorksopace . StartEditing ( false ) ;           editWorksopace . StartEditOperation ( ) ;           feature . set_Value ( index , "Hallo" ) ;           feature . Store ( ) ;                    editWorksopace . StopEditOperation ( ) ;           editWorksopace . StopEditing ( true ) ;      }      var result = new JsonObject ( ) ;      result . AddString ( "Status" , "OK" ) ;      return Encoding . UTF8 . GetBytes ( result . ToJson ( ) ) ; } ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ I still get the same error, although I even check if the field of that feature is editable.  ...

I followed the samples from ESRI (e.g. this one from GitHub) to enable feature-access to my service and everything worked fine. Next I changed the URL into my own feature-service and provided my crendetials to access that service. So I ended up with the following code: //var serviceUrl = " http://sampleserver6.arcgisonline.com/arcgis/rest/services/DamageAssessment/FeatureServer/0 "; var serviceUrl = " https://myhost/arcgis/rest/services/MyService/FeatureServer/0 " ; ServerInfo serverInfo = new ServerInfo {      ServerUri = new Uri ( serviceUrl ) ,      TokenAuthenticationType = TokenAuthenticationType . ArcGISToken ,      TokenServiceUri = new Uri ( " https://myhost/arcgis/admin/generateToken " ) } ; AuthenticationManager . Current . RegisterServer ( serverInfo ) ; AuthenticationManager . Current . ChallengeHandler = new ChallengeHandler (      async info = >           await AuthenticationManager . Current . GenerateCredentialAsync ( info . ServiceUri , user , password ,                info . GenerateTokenOptions ) ) ; var featureTableUri = new System . Uri ( serviceUrl ) ; var table = new ServiceFeatureTable ( featureTableUri ) ; var queryParameters = new QueryParameters { WhereClause = "1 = 1" } ; FeatureQueryResult features = await table . QueryFeaturesAsync ( queryParameters ) ; ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ When I execute this code I get the following exception on the last line, which doesn´t seem very meaningful to me: Exception thrown : 'System.InvalidOperationException' in mscorlib . dll Additional information : Cannot call this method in this context : Object failed to load , unable to execute task . ‍‍ ‍ ‍ ‍ When I set a breakpoint on the GenerateCredentialAsync-line (line 12) I also notice it´s never hit. So I wonder if the challengehandler is even registered correctly and fires the challenge-event appropriately. ... View more

We´re are re-designing our desktop-app which consists of some millions of lines of ArcObjects-code. To do this, we plan to create a prototype based on ArcGIS Server and the Runtime SDK. But in contrast to the samples we plan to use the runtime-client as a service to access it within a WebGIS, where the actual presentation happens. So we end up a three-tier-architecture with an ArcGIS-Server as data-layer, the runtime-app as business-layer and the web-client as presentation-layer. So my question is if this is possible with the runtime-SDK or if there are better oppourtunities to extend the ArcGIS-server with some business-logic.  Some words to that logic: currently it contains dozens of event-handlers registered to the events propagated by ArcMap as well as the geodatabase. So in order to store a feature, we need to be able to implicitely update other features that may be related. This in fact triggers recursive store-operations to those features. Another feature we´re currently using and extending is the ability to undo and redo operations or even rollback the entire session. I know this question is fairly complex and not easy to answer. But so far we couldn´t get any idea on which framework to use. ... View more

I created an ITool (not an AddIn) which I embed within a toolbar ( MyToolbar ). The code for the entire toolbar is located within one single assembly, let´s call it  MyAssembly . It´s written in C#, which compiles for .NET 3.5, x86 in debug-mode. All PDB-files are appropriately copied to my assemblies bin-folder. Here is some short code for the toolbar: Snippet namespace MyNamespace . Toolbars {      using System ;      using System . Runtime . InteropServices ;      using System . Collections . Generic ;      using ESRI . ArcGIS . SystemUI ;      using ESRI . ArcGIS . ADF . CATIDs ;      [ System . Runtime . InteropServices . ComVisibleAttribute ( true ) ]      #region "COM GUIDs"      [ ClassInterface ( System . Runtime . InteropServices . ClassInterfaceType . None ) ]      [ Guid ( "D8F25094-0F43-4aea-83C6-8DE4187101C9" ) ]      #endregion      public sealed class MyToolbar : IToolBarDef      {           #region Component Category Registration           [ ComRegisterFunction ( ) ]           static void Reg ( String regKey )           {                MxCommandBars . Register ( regKey ) ;           }           [ ComUnregisterFunction ( ) ]           static void Unreg ( String regKey )           {                MxCommandBars . Unregister ( regKey ) ;           }           #endregion      }      // ...      // implementation for IToolbar      // ... } ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ Now I start ArcMap and try to attch that code to it. When I set any breakpoint, it´ll not hit, because "no symbols have been loaded for this document". I allready uninstalled my assembly from GAC and used esriregasm to unregister any potential previous version of the file. To do so I used this: esriregasm.exe /p:desktop /u /s MyAssembly.dll‍‍‍ ‍ To re-register I have some post-processing within my VS-project that calls esriregasm again < Target Name = " AfterBuild " > < Exec WorkingDirectory = " $(CommonProgramFiles)\ArcGIS\bin " Command = " esriRegasm.exe &quot;$(TargetPath)&quot; /p:Desktop /s " /> </ Target > ‍‍‍‍‍‍‍‍‍‍‍‍ ‍ ‍ ‍ I also re-started VS and my computer as well, cleaned my solution and rebuilt it (which is the standard procedure for this problem when attaching any .NET-code to a program), however I still can´t break into the code. Another possibly related issue to this is, that I can´t put my toolbar into ArcMap. As soon as I add the toolbar via RightClick --> MyToolbar, ArcMap crashes without any error-message, not even in its log-file. ... View more
