Syntax
Remarks

To create a Map, you must call one of the create methods of the MapFactory class.

To open a map, use ProApp.Panes.CreateMapPaneAsync method.

You can also think of a Map as a container of layers, StandaloneTables, bookmarks etc. You need to use a MapView to interact with a map. Multiple MapViews can be opened for a Map at a given time, but there can only be one active MapView which is returned by the MapView.Active static member. Use the Map property to access the Map object associated with the MapView. The Map object has properties that operate on all layers within the map, such as spatial reference, reference scale, and so on, along with methods that manipulate the map's layers.

Example
Get the active map
Map map = MapView.Active.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...
});
Find a map within a project and open it
public static async Task<Map> FindOpenExistingMapAsync(string mapName)
{
  return await QueuedTask.Run(async () =>
  {
    Map map = null;
    Project proj = Project.Current;

    //Finding the first project item with name matches with mapName
    MapProjectItem mpi = proj.GetItems<MapProjectItem>()
      .FirstOrDefault(m => m.Name.Equals(mapName, StringComparison.CurrentCultureIgnoreCase));
    if (mpi != null)
    {
      map = mpi.GetMap();
      //Opening the map in a mapview
      await ProApp.Panes.CreateMapPaneAsync(map);
    }
    return map;
  });

}
Open a webmap
Map map = null;

//Assume we get the selected webmap from the Project pane's Portal tab
if (Project.Current.SelectedItems.Count > 0)
{
  if (MapFactory.Instance.CanCreateMapFrom(Project.Current.SelectedItems[0]))
  {
    map = MapFactory.Instance.CreateMapFromItem(Project.Current.SelectedItems[0]);
    await ProApp.Panes.CreateMapPaneAsync(map);
  }
}
