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 http://go.microsoft.com/fwlink/?LinkID=241478.
We’re lucky this time, renewing the certificate is very easy. Just follow below steps (copied from MSDN).
- In Solution Explorer, open the shortcut menu for the .appxmanifest file, choose Open With, and then choose App Manifest Designer.
- In the App Manifest Designer, choose the Packaging tab, and then choose the Choose Certificate button.
- In the Choose Certificate dialog box, expand the Configure Certificate list, and then choose Create test certificate.
- 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.
