1. Follow this link

this will give you intellisence support for all MGOS schemas.

2. I am adding layer to the map this way:
        /// <summary>
        /// Add new layer to MG repository and to the map
        /// </summary>
        /// Layer name
        /// Layer legend label
        /// Layer group name
        /// Layer group legend label
        /// Layer (of type point) attributes to populate with
        /// SQL table (or View) column list
        public void AddPointLayerDef2Map(
            String layerName
            , String layerLegendLabel
            , String groupName
            , String groupLegendLabel
            , LayerPointAttributes attributes
            , DataTable dbColumns)
            // Get or set the resourceid of the map to load
            MgResourceIdentifier resourceMap = new
            // Define a new resourseLayer
            MgResourceIdentifier resourseLayer = new
MgResourceIdentifier(this.Attributes.MgLayerName(layerName, groupName));
            // Create our connection to the resource service
            MgResourceService resourceService =
            // Get new Layer XML
            String xmlLayer = Spatial.Helper.GetLayerXml(attributes,
            // Save it
            // TODO: AS: I think we have to use UpdateResource in case layer
already exists on the map.
            // Confirm and update logic
            resourceService.SetResource(resourseLayer, new
MgByteReader(xmlLayer, MgMimeType.Xml), null);

            // TODO: Check if there is map available and if not:
            // 1. Create map
            // 2. Create layer
            // Get updated map XML
            String xmlMap = Spatial.Helper.GetMapXml(
                , resourceMap
                , resourseLayer
                , layerName
                , layerLegendLabel
                , groupName
                , groupLegendLabel);
            // Save it
            resourceService.SetResource(resourceMap, new
MgByteReader(xmlMap, MgMimeType.Xml), null);
