How do I renew my expired Windows Store app certificate?

Question

I have taken over the development of a Windows Store app, and our store certificate has recently expired. How do I renew the certificate, or do I have to generate a new one?

In the .appxmanifest, I can choose to generate a new Test certificate, but I need a store certificate, not a test certificate.

You need to:

1. Generate new test certificate http://msdn.microsoft.com/en-us/library/br230260.aspx#Renew
2. Associate with store app: Project -> Store -> Associate
