Example 

ArcGIS.Desktop.Mapping Namespace > MapView Class > ZoomTo Method : ZoomTo(Camera,Nullable<TimeSpan>) Method
The new camera to use for the view.
The amount of time to navigate the view to the new camera position. If null it uses the default navigation duration.
Zoom the view to a camera position. This method must be called on the MCT. Use QueuedTask.Run.
Syntax
Public Overloads Function ZoomTo( _
   ByVal camera As Camera, _
   Optional ByVal duration As Nullable(Of TimeSpan) _
) As Boolean

Parameters

camera
The new camera to use for the view.
duration
The amount of time to navigate the view to the new camera position. If null it uses the default navigation duration.

Return Value

True if the navigation is completed, false if it was interrupted by another view navigation.
Exceptions
ExceptionDescription
This method or property must be called within the lambda passed to QueuedTask.Run.
Remarks
This is equivalent to setting the camera position for the view. Use this method in combination with Camera /> to get and then modify the position of the view's camera. If the camera's spatial reference is in a different spatial reference than the map this method projects the camera into the spatial reference of the map.
Example
Rotate the active map view.
public Task<bool> RotateViewAsync(double heading)
{
  return QueuedTask.Run(() =>
  {
    //Get the active map view.
    var mapView = MapView.Active;
    if (mapView == null)
      return false;

    //Get the camera for the view, adjust the heading and zoom to the new camera position.
    var camera = mapView.Camera;
    camera.Heading = heading;
    return mapView.ZoomTo(camera, TimeSpan.Zero);
  });
}
