    This is slightly odd as it doesn’t appear in intellisense, but you can use:

    var dispatcher = myDispatcherObject.Dispatcher;
    if (dispatcher.CheckAccess()) { /* ... */ }
    

    As all UI components inherit from DispatcherObject this should solve your specific problem, but it is not specific to the UI thread – it can be used for any dispatcher.
