Setting up a pull operation for sharing a file RRS feed

  • Question

  • I'm trying to create a text file to send to the share charm. I'm using a pull operation because the process can take longer than the 200 milliseconds that is allocated to a normal sharing operation. I'm using the following code:

        private async void OnDeferredShareRequestHandler(Windows.ApplicationModel.DataTransfer.DataProviderRequest e)
            Windows.ApplicationModel.DataTransfer.DataProviderDeferral Deferral = e.GetDeferral();
                Windows.Storage.IStorageFile TempFile = await Windows.Storage.ApplicationData.Current.TemporaryFolder.CreateFileAsync("TEMP", Windows.Storage.CreationCollisionOption.ReplaceExisting);
                await Windows.Storage.FileIO.WriteTextAsync(TempFile, "test");
            catch (System.Exception exception)

    But this isn't working. It throws the following error:

    > An exception of type 'System.Exception' occurred in App.exe but was
    > not handled in user code WinRT information: Unable to create
    > StorageItems from the passed in object. Additional information: Type
    > mismatch. Unable to create StorageItems from the passed in object. If
    > there is a handler for this exception, the program may be safely
    > continued.

    What am I doing wrong? How can I fix this so that I can share the file properly?

  • Which line of code is throwing the exception? Can you post a reproduction app for testing?

    NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined objects and unknown namespaces.
