GIT Hub Workflow Actions with Multi Repositories

Question

I am working on a multi repo .NET workflow where the master solution has a dependence on 2 child projects.

My yml is able to to checkout all three repos without issue. When I run a dot net restore on the 2 child projects, everything works. However, when I restore the master solution, the dot net restore indicates it cannot find the 2 child projects.

Any idea what I am missing?

Here is an example of my yml

name: Pipeline for WebAPI Deployment

on:
  push:
    branches:
      - main
  workflow_dispatch:

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
    - name: Checkout Child1.NET Repository
      uses: actions/checkout@v4
      with:
        repository: TheClient/Child1.NET
        token: ${{ SuperSecretToken}}
        path: Child1.NET
        ref: 'main' 

    - name: Checkout Child2.NET Repository
      uses: actions/checkout@v4
      with:
        repository: TheClient/Child2.NET
        token: ${{ SuperSecretToken}}
        path: Child2.NET
        ref: 'main' 

    - name: Checkout Master.NET Repository
      uses: actions/checkout@v4
      with:
        repository: TheClient/Master.NET
        token: ${{ SuperSecretToken}}
        path: Master.NET
        ref: 'main' 

    - name: Setup .NET
      uses: actions/setup-dotnet@v2
      with:

      shell: pwsh

    - name: Display MASTER_SOLUTION_PATH
      run: echo "MASTER_SOLUTION_PATH is set to $env:MASTER_SOLUTION_PATH"
      shell: bash

I found the root cause of the issue. It turns out that GIT runners will change the case of your folder structure. You will need to display where the projects are located and then you will will need to change the project file of the main project to match the folder references. Utlimately, this is a small amount of work for an enormous gain.
