I'm running into what I think is a bug with
HttpClient and the asynchronous
ReadAsByteArrayAsync function. It's pretty simple: I have a button with an
async action that downloads a remote file using the
ReadAsByteArrayAsync function. The download seems to complete successfully every time, but the window containing the button disappears.
I've uploaded a sample project reproducing the bug here: https://github.com/tdenniston/XamAsyncDownloadBug
To reproduce the bug, run the application, click the button to show the download window, and then click the button to download the file asynchronously. Sometimes the window will disappear on its own, and sometimes it will disappear if, during the download, you click back to the main window.
