I'm still investigating how to avoid that so basically if I cache a IRandomAccessStream that was opened by another async method and try to use it in a normal method I got access_denied_exception.

And the easiest way to get the data is to call OpenAsync() in advance, before the handler is invoked, cache it and use it inside of the handler. @Cristoph You still are able to call SetBitmap(), but you are right that before calling it you will need to get the actual data.

So you have an event handler method where you need to do set some arguments after you 'await' something. So how do you set arguments?? . What you are saying is not not use async method so not use await, so in fact it means you CANNOT SetBitmap(...) you have to move the logic from inside this method? @Andrei, I still don’t get what you mean with the fix for the second example.

The idea is to convert DataRequestedHandler into a fully sync method. That means OpenAsync should not only be moved into a new method, but this new method should be also called from some other place, not from DataRequestedHandler method. Thanks Jeremy!

About your second example, I'm not sure to understand the fix. You can move the OpenAsync call to another method, but this method will still be async right ? How to return the data to the handler synchronously then ? Regards Nice post. About your second example, I’m not sure to understand the fix.
