Question

For a view constructed using WPF, I want to change the mouse cursor to a hourglass when the application is busy and nonresponsive.

One solution is to add

Answer 1

I am simply doing

Mouse.OverrideCursor = Cursors.Wait;
try {
    // Long lasting stuff ...
} finally {
    Mouse.OverrideCursor = null;
}

According to the documentation of Mouse.OverrideCursor Property

To clear the override Cursor, set OverrideCursor to null.

The try-finally statement ensures that the default cursor is restored in any case, even when an exception occurs or the try-part is left with return or break (if inside a loop).
