Unknown publisher error while executing exe

I have deployed my windows app project but when i run it it first throws an error "Unknown publisher". How to hide this message?

Why does it say unknown publisher?

An unknown publisher is a software creator whose identity isn't verified by your device's operating system (such as Windows or MacOS) or web browser (like Google Chrome).

How do I unblock unknown publisher in Windows 10?

Go to the Content tab, Look under the Certificates section. Click on Publishers button. Select the Untrusted Publishers tab. Select the Publisher you wish to unblock and click the Remove button.

You have to digitally sign your package to prevent this type of error.

But typically it is advised not to worry about this at the development stage of the application but only consider this at the shipping time.
