System.Threading.Thread replacement in windows store apps

Question

Is it right that 'System.Threading.Thread' douesn't exist in Windows Store Apps? And if it is, what is the replacement (I want to run a function in the background so the UI douesn't freez while calculating something). Language is C# and XAML for the UI.

Answer 1

Use Task.Run or Task.Factory.StartNew

private void BackgroundWork() { ... }

public async Task DoUsefulWorkAsync()
{
    // Do useful work
    // Start Background Job
    Task backgroundWorkTask = Task.Run(() => BackgroundWork());

    // Do more useful work

    // Wait async for BackgroundWork to complete
    // It won't block the UI thread that we're running on
    await backgroundWorkTask;
}
