Example

How to add a new map to a project

await QueuedTask.Run(() =>
{
  //Note: see also MapFactory in ArcGIS.Desktop.Mapping
  var map = MapFactory.Instance.CreateMap("New Map", MapType.Map, MapViewingMode.Map, Basemap.Oceans);
  ProApp.Panes.CreateMapPaneAsync(map);
});

Create a new map with a default basemap layer

await QueuedTask.Run(() =>
{
  var map = MapFactory.Instance.CreateMap(mapName, basemap: Basemap.ProjectDefault);
  //TODO: use the map...
});

Open a diagram pane from a Network Diagram

// Create a diagram layer from a NetworkDiagram (myDiagram)
DiagramLayer diagramLayer = await QueuedTask.Run<DiagramLayer>(() =>
{
  // Create the diagram map
  var newMap = MapFactory.Instance.CreateMap(myDiagram.Name, ArcGIS.Core.CIM.MapType.NetworkDiagram, MapViewingMode.Map);
  if (newMap == null)
    return null;

  // Open the diagram map
  var mapPane = ArcGIS.Desktop.Core.ProApp.Panes.CreateMapPaneAsync(newMap, MapViewingMode.Map);
  if (mapPane == null)

  return newMap.AddDiagramLayer(myDiagram);
});
