I am creating an application using the Bing Mpas WPF control that needs to display a variable number of Pushpins. The number and identity of the Pushpins varyover time (data from a database or binding) and the location of each pushpin needs to be adjusted using information coming from a number of GPS streams running in a separate (background) scanning thread.
The changes in GPS data generate location update events, and I need the Pushpins to move accordingly. Unfortunately I cannot seem to get around the problem of cross-threading errors. I am using the MVVM design model. Any suggestions?

Pushpinpin = newPushpin();
newLocation( latitude, longitude );
pin.ToolTip = incident.Text511;
this.MyMap.Children.Add( pin );

Thanks steve - I have now used a slight variant of your suggestion, using the Dispatcher, and it works fine.
I now have multiple pushpins jumping all over the map in real time, just as planned!
