Help the DVLUP Challenge: Go ahead, rate my app!

The DVLUP program has an interesting challenge: Go ahead, rate my app!

This challenge wants your app to encourage feedback. Yeah just feedback, similar to an article I wrote about a year ago for Windows Style apps. The interesting thing is that you don’t have to do that much. The challenge already contains code you can copy/paste.

But wait, there’s more, of course we want the words and sentences that appear in the dialogs to be localized, don’t we? I would love to add this to my P | Cast app. But my app is localized in a lot of different languages.

So please join me and help improve the Helperslib project, based on the code that’s provided by DVLUP, improved and made available on NuGet by @SimonDarksideJ. I already added Dutch to the Git Repository. Why don’t you add your native languages?

Windows Store Apps, Error: The certificate specified has expired.

Today I tried to update one of my Windows Store Apps. When I tried to create an App Package for the Store I got an error. One that was completely new to me.

The certificate specified has expired. For more information about renewing certificates, see

We’re lucky this time, renewing the certificate is very easy. Just follow below steps (copied from MSDN).

  1. In Solution Explorer, open the shortcut menu for the .appxmanifest file, choose Open With, and then choose App Manifest Designer.
  2. In the App Manifest Designer, choose the Packaging tab, and then choose the Choose Certificate button.
  3. In the Choose Certificate dialog box, expand the Configure Certificate list, and then choose Create test certificate.
  4. In the Create test certificate dialog box, click the OK button.

In the end Visual Studio will generate the new certificate with a new expiry date. The new certificate will be valid for a full year.
