ClickOnce manifest problem

[sinanakyazici]

Hi guys, I'm trying simple demo .net core 3.1 application for clickonce like below.

I get an error " the manifest may not be valid or the file could not be opened." when I try to publish application.

I uninstalled CefSharp.WinForms package. I don't get any error when I publish application.

Why does CefSharp.WinForms cause an error for manifest ?

This error log:
