StartNew() with Application.Current.Dispatcher.Invoke blocks

Given this code:

Task.Factory.StartNew(() =>
{
    Application.Current.Dispatcher.Invoke(() =>
    {
        //UI Code 1            
    });
    //Non UI Code
    taskResult = SomeMethod();
    Application.Current.Dispatcher.Invoke(() =>
    {
        //UI Code 2
        if (taskResult)...
    });
});

Is UI Code 2 executed after the Non UI Code is finished with execution or does it execute while Non UI Code is still running?

In other words, is it safe to assume that taskResult variable will always have the results of Non-UI thread processing when called within UI Code 2 block?

Given MSDN description for Dispatcher.Invoke:

Executes the specified delegate synchronously on the thread the Dispatcher is associated with.

The answer to your question is Yes.
