Universal Windows 10 WebView - how to clear / disable cache?

Question

I'm having trouble clearing the WebView cache in a UWP application.

If I edit the contents of the JS file associated with my HTML page, I cannot get the change in my application unless I reinstall the application.

The static method of WebView.ClearTemporaryWebDataAsync () does not seem to work.

I also tried adding headers to the request to disable caching:

private void reloadPage()
{
    string url = getUrl();
    HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, new Uri(url));
    request.Headers.Add("Cache-Control", "no-cache, no-store, must-revalidate");
    request.Headers.Add("Pragma", "no-cache");
    myWebView.NavigateWithHttpRequestMessage(request);
}

I also tried the following: on punt (I'm not sure if this affects the behavior of WebView caching), but still there is no joy:

private void onWebviewLoaded(object sender, RoutedEventArgs e)
{
    Windows.Web.Http.Filters.HttpBaseProtocolFilter myFilter = new Windows.Web.Http.Filters.HttpBaseProtocolFilter();
    myFilter.CacheControl.WriteBehavior = Windows.Web.Http.Filters.HttpCacheWriteBehavior.NoCache;
    myFilter.CacheControl.ReadBehavior = Windows.Web.Http.Filters.HttpCacheReadBehavior.Default;

    WebView.ClearTemporaryWebDataAsync().AsTask().Wait();
    reloadPage();
}

Any help would be greatly appreciated!
