WinRT: Loading static data with GetFileFromApplicationUriAsync()

Question

I have some data in my windows 8 application which should be shipped with and is just some static data. In fact: It\'s a simple xml file which should get deserialized.

Thanks for posting code. Please try to change your method Load as the following:

//your code
var file = await StorageFile.GetFileFromApplicationUriAsync(uri).AsTask().ConfigureAwait(false);
//your code
var stream = await file.OpenStreamForReadAsync().ConfigureAwait(false);
//your code

The main difference here is AsTask().ConfigureAwait(false)

EDIT:

Good to hear that it's working. Explanation is quite simple: when you use task.Result or task.Wait() on GUI thread in conjunction with await keyword you're causing deadlock. This happens because after awaiting code is resumed on the same context it was invoked (in your case - GUI thread). And because GUI thread currently waiting for task to complete (via Result or Wait()) deadlock arises and code after await keyword will never be invoked. ConfigureAwait(false) specifies that current context can be ignored and thus allows your code to complete successfully.
