I'm trying to let the user browse for a file with the FileOpenPicker class, but when I use the PickSingleFileAsync function with await, I get following error:
'IAsyncOperation' does not contain a definition for 'GetAwaiter' and no extension method 'GetAwaiter' accepting a first argument of type 'IAsyncOperation' could be found (are you missing a using directive for 'System'?)
This is the function that gives the error on it's last line:
private async void browseFileButton_Click(object sender, RoutedEventArgs e) {
FileOpenPicker filePicker = new FileOpenPicker();
filePicker.ViewMode = PickerViewMode.Thumbnail;
selectedFile = await filePicker.PickSingleFileAsync();
}
The documentation from Microsoft contains an example that uses the FileOpenPicker in the same way. Has anybody had this problem or has anybody a solution for this problem?
