Before you call the 3rd party function, get a reference to Dispatcher.CurrentDispatcher. In the callback function, use dispatcher.Invoke.

What you end up with will look something like this:

class MyClass
{
    private Dispatcher dispatcher;
    public void runThirdParty()
    {
        this.dispatcher = Dispatcher.CurrentDispatcher;
        callThirdPartyFunction(myCallBack);
    }

    public void myCallBack()
    {
        this.dispatcher.Invoke(new Action(() =>
        {
            //code to run here.
        }));
    }
 }
