Certificate expiration?

Emil Alipiev 306

my uwp apps certificate will expire on 24th January 2021 but when i try to create a package, i am getting an error message as T

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

why?

Should i now create a new certificate? because i cannot find any option to extend expiry date of the certificate.

What happens if i dont make a new submission with a renewed certificate? Users cannot install my from Microsoft Store? And how does this affect existing users installed my uwp app?

Hello,

Welcome to Microsoft Q&A!

Visual Studio will automatically create a certificate for uploading your app to the Store when you associate your app with Store at the first time or when your certificate expires.So you could re-associate your app with store to renew the certificate.

Use Visual studio to associate your app with the Microsoft Store:In Solution Explorer, right-click your project and then select Store > Associate App with the Store > Next >(sign in to the Microsoft Store) > select the App Name you have reserved>Next > Associate.

Then you could create a new package with the new certificate, upload it to the store and update your app.

Thank you.

I dont have the store menu when I right click on my uwp app. It used to be there but latest version 16.8.3, it doesnt appear. Beside that I am using Azure Devops to generate a bundle. How to get a new certificate for signing without store?

ok i have just found out that store menu was renamed as Publish. but my 2nd question remains. I use Azure Devops and i need to generate certificate to sign with msbuild. When I associate, Pfx file on my disk wasnt updated. How to get it or export it?

I've to say that the certificate is managed by the store. Generally, you need to update your app in the Store first and then get the new certificate on your local device.

A possible way is that when you create a new package of your app after you renew the certificate, you will get a folder which contains a .cer file. You could try to import the new certificate and use it in Azure DevOps.

If this does not work, then you have to go back to the old way, package the app in visual studio, upload it to the store, update your app on your device, then you should be abled to get the new certificate.

whole this thing is not clear at all. there are 2 options. select from store, when i choose this, it selects same certificate with expiry date 24.01.2021. It looks like that from store i can only renew it after it expires right?
and create new certificate is suggest only for test certificate documentation

But why do i get error message as

The certificate specified has expired.

although there is still time till 24.01.2021.

i mean here https://learn.microsoft.com/en-us/windows/msix/package/create-certificate-package-signing?WT.mc_id=DT-MVP-5001828#create-a-self-signed-certificate

it says that self signed certificates are only for testing. that means we should get it from store right? but somehow i cannot use the store signed certificate in azure devopps to package.

Self-signed certificates are used just for testing, it is not suitable to use them for publishing. Is the store signed certificate you mentioned the one that generated by the store when you have uploaded your package? If you just want to update your app, why not try to upload your package and update your app manually in partner center instead?

HI, my case is different a little bit. That is our client does not want to upload app to store, we will build and give them release bundle and the bundle is using develop certificate and the certificate will be expired after 1 year. The question is I can extend the expired date or not, and how to do it. If not, what should I do? Rebuild the app with another certificate?
