ExceptionDescription
This method or property must be called within the lambda passed to QueuedTask.Run.
Example
// Use a builder convenience method or use a builder constructor.

MapPoint point1 = null;
MapPoint point2 = null;

// Builder constructors need to run on the MCT.
ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() =>
{

    bool bhasID = mb.HasID;        // hasID = false

    // do something with the builder

    point1 = mb.ToGeometry();

    // change some of the builder properties
    mb.X = 11;
    mb.Y = 22;
    mb.HasZ = false;
    mb.HasM = true;
    mb.M = 44;
    // create another point
    point2 = mb.ToGeometry();

// Builder convenience methods don't need to run on the MCT.

hasM = point3.HasM;             // hasM = false
hasID = point3.HasID;           // hasID = false


// builderEx constructors don't need to run on the MCT.
MapPointBuilderEx builderEx = new MapPointBuilderEx(point1);
x = builderEx.X;              // x = 1.0
y = builderEx.Y;              // y = 2.0
