I think it's better to do something like

public Task Something(Task task)
{
    async Task Call()
    {
        await task;
        SetEvent();
    }
}

@ahmed605 What is your opinion too? I can't be sure the current code and the above code is really non blocking.

What's the state of this PR?

Committed the requested change. Itested the change in RedirectActivationTo on my local but didn't test the one in OpenFileFromTile as I don't have Windows 10 rn.
