Unknown Publisher in Set Up project in WPF

Question

I am using Microsoft Visual Studio Installer Projects to create a set up project for my WPF application using .NetCore in Visual Studio 2019. How can I change the publisher from unknown to known when installing the application?

Answer 1

As Daisy correctly answered, to change the Publisher name from Unknown to your Firm name,
you need a Certificate to sign the Executable file and DLLs you produce.
The certificate can be bought by the same organizations selling SSL certificates, but is a different kind of certificate.
Where a third party certificates that you are you ;) after the signing the Setup program shows your name instead of the Unknown.

The signing can be done using signtool.exe that is available in the windows 10 sdk.
