UWP app -Invalid package family name, after update certificate

I created app for uwp (win 10 desktop). I could not build package for store. I received an error: it is necessary to update the certificate. I have updated certificate and build my package. But when I upload the package to the store, I get the error:

Invalid package family name: MyPackage.xxxx_xxxx (expected: MyPackage.yyyy_yyyyy)
Invalid package publisher name: CN=XYX (expected: CN=xxx-xxxx-xxx-xxxx)

But I opened my app manifest and I see:

Published: CN=xxx-xxxx-xxx-xxxx
Package Family Name: MyPackage.yyyy_yyyyy

It is what expected. In "open sertificate" I see : Publisher -XYX.

How do I fix it all? Any ideas?

This issue still exists even in Visual Studio 2022. I have been trying to complete my .net MAUI app and the "Store Association" has been my biggest headache and obstacle. No matter how many times i did the "Store Association" i could never get it to stay associated. All my problems for the last 6 weeks have been caused by the CN on the certificate being wrong. And i didnt realize it until i decided to upload to the store to see if that would help and i got the error mentioned.

For us, the problem was that we tried to publish the app before associating it with a submission. The fix was the following:

  1. Delete the temporary key .pfx file at the root of the directory
  2. Re-associate the app with the store via the Publish menu

Update for Visual Studio 2019

  1. Open Package.appxmanifest from Solution Explorer
  2. Go to "Packaging" tab
  3. Copy Publisher name after CN=. Looks like a GUID
  4. Click "Choose Certificate..."
  5. Click "Configure Certificate..."
  6. Click "Create..."
  7. Paste GUID from #3 into "Publisher Common Name"
  8. Proceed to create and save certificate

Problem seems that it defaults to developer name instead of using the original GUID

I solved this issue. I made a mistake when creating new certificate. It must be so:

  1. Open Package.appxmanifest.
  2. Go to the "Packaging" tab.
  3. Copy Publisher DN(number after CN=)
  4. Click the button "Choose Certificate" and select the item "Create test certificate..."
  5. Copy the publisher DN from step 3 to the first editable text field

I found this MSDN blog: https://blogs.msdn.microsoft.com/jamiedalton/2017/01/13/windows-store-error-updating-package-invalid-package-family-name/

The blog states that you should associate your App to the Store App using Visual Studio.

This seems to be the right answer.
