Race condition with Interlocked.Exchange
Hi, I found a weird bug which I can't quite understand...
This is my class: https://github.com/AngryCarrot789/FramePFX/blob/master/FramePFX/Utils/RDA/RateLimitedDispatchAction.cs, it lets me add forced minimum interval between sequential executions (e.g. say you're dragging around a UI control but you only want to update the position text every say 0.1 seconds)
InvokeAsync is called by the user and it choses whether to create a new task or set the current task to a "continue" state. ExecuteCore actually executes the action.
At the very bottom is a generic parameter version, and at one point I hit a break point on the Debug.Assert(false) statement, which to me should be impossible, because
