CreateOrEditTile causing app to crash

[MasterChiefMasterChef]

Hi,

When I create a live tile, everything works fine. Unfortunately, if the button is pressed twice, no tile is created. I know better than to press the button twice in a row, but my users don't. I'm just trying to avoid the crashes that I keep getting reported on my app. This is present in your 'Telerik Examples' app as well. If you press the 'pin to start' button twice, no tile will be pinned to the start. Is there any way to get around this error?

Hello Master Chief,

Thank you for writing.

This is indeed an interesting scenario which can be also reproduced with the native method ShellTile.Create. We use this method internally and obviously when the tile creation process is in progress a new process can't be initiated. Here's how you can workaround this:

private bool isTileUpdateInProgress = false;

private void Button_Click(object sender, RoutedEventArgs e)
{
    if (isTileUpdateInProgress)
    {
        return;
    }
    isTileUpdateInProgress = true;

    // Create or update your tile here

    Dispatcher.BeginInvoke(() =>
    {
        isTileUpdateInProgress = false;
    });
}

I hope this information helps.

Thanks!

I tried doing something very similar to this, with no success. This version you sent me works perfectly!
