github-actions-push-nuget-to-github-packages.md

Add RepositoryUrl property to the project .csproj file

<Project Sdk="Microsoft.NET.Sdk">

 <PropertyGroup>
   <TargetFramework>net5.0</TargetFramework>
   <RepositoryUrl>https://github.com/PATH/TO/REPOSITORY</RepositoryUrl>
 </PropertyGroup>

</Project>

Github Actions (.yml file) should look like this

name: Build and Pack (push to github packages)

on:
  push:
    branches: [ master ]
  pull_request:
    branches: [ master ]

jobs:
  build-Pack-Push:
    runs-on: ubuntu-latest
    permissions:
      packages: write
      contents: read
    
    env:
      PROJECT_NAME: #YOUR_PROJECT_NAME#
      GITHUB_USER: #YOUR_GITHUB_USERNAME#
  
    steps:        
      
    - name: Checkout
      uses: actions/checkout@v2
      with:
        fetch-depth: 0
          
    - name: Install GitVersion (by GitTools)      
      uses: gittools/actions/gitversion/[email protected]
      with:
        versionSpec: '5.x'    
    - name: Determine GitVersion
      id: gitversion
      uses: gittools/actions/gitversion/[email protected]
    - name: Display Generated SemVer
      run: |
        echo "NuGetVersionV2: ${{ steps.gitversion.outputs.nuGetVersionV2 }}"
            
    - name: Setup .NET
      uses: actions/setup-dotnet@v1
      with:
        dotnet-version: 5.0.x
    - name: Restore dependencies
