Building a nuget .Net Framework web application package using msbuild and TeamCity? - msbuild

Question

What is the method to create a web application nuget package with TeamCity?
I'm totally confused after .NET became a thing.
What I'm attempting to do, is to create a nuget package with a .Net Framework 4.8 webapplication in it.
The ways things worked before, seems to be outdated or deprecated.
In TeamCity, the meta runners that were used previously are either deprecated or not functioning very well.
When I'm googling f.ex. msbuild
https://learn.microsoft.com/en-us/nuget/create-packages/creating-a-package-msbuild
I get stuff about .Net Core and .Net Standard, nothing about .Net Framework. And the stuff is often 10 years old or more.
I might have gone stupid after how nuget works in .NET, since everything is tied to projects and you can actually avoid having code shipped (the cs files) with the web application.

Answer 1

The closest I've gotten so far, is by making a comprehensive .nuspec file, then run in the project directory of the web application after the project has been built with all necessary dependencies.
However, the build output will log warnings:
WARNING: NU5100: The assembly 'bin\Antlr3.Runtime.dll' is not inside the 'lib' folder and hence it won't be added as a reference when the package is installed into a project. Move it into the 'lib' folder if it needs to be referenced.
The nuget pack command
nuget pack <path to nuspec file>
The nuspec file:
<?xml version="1.0" encoding="utf-8"?>
<package>
<metadata>
<id>MyPackageId</id>
<version>1.0.0.0</version>
<title>My application title</title>

Rather comprehensive ...
