How do I improve this GitHub Action that GitHub Copilot recommended?

I had a repo on Azure DevOps Services (ADS). I had an ADS YAML file that deployed my ASP.NET application to a web server I use. It worked OK for some years, but it was having problems recently, and since I've been used to using GitHub, I felt it was time to migrate it to GitHub. So, I migrated it last month to GitHub.

Starting with the YAML file I used on ADS, I've modified it to work here using GitHub Actions. I began yesterday, then completed it today. By that I mean that it ran to completion, without any errors. To help me with this I used GitHub Copilot to assist me with the YAML. The original ADS YAML file was one job. GitHub Copilot's version has two jobs, build and deploy. Please also note that the web service I'm using is on a Windows Server, so I specify runs-on: windows-latest in the workflow file. As much as I like using GitHub Copilot, I think it has duplicated some tasks between the build and deploy jobs. For example, both jobs do a dotnet build, which doesn't make sense to me. If I'm correct that GitHub Copilot has duplicated tasks unnecessarily, how do I simply it? Here is the YAML file:

name: Deploy to InterServer

on:
  push:
    branches: [ "main" ]
  pull_request:
    branches: [ "main" ]
  workflow_dispatch: # manual trigger

jobs:
  build:
    runs-on: windows-latest

    env:
      SOLUTION_LOCATION: MYAPP/MYAPP.sln
      PROJECT_LOCATION: MYAPP/MYAPP/MYAPP.csproj
      PUBLISH_PROFILE: win-x64

    steps:
    - uses: actions/checkout@v4
    
    - name: Setup .NET
      uses: actions/setup-dotnet@v4
      with:
        dotnet-version: 10.0.x
        
    - name: Restore dependencies
      run: dotnet restore ${{ env.SOLUTION_LOCATION }}
      
    - name: Build
      run: dotnet build --no-restore --configuration Release ${{ env.SOLUTION_LOCATION }}
      
    - name: Test
      run: dotnet test --no-build --verbosity normal --configuration Release ${{ env.SOLUTION_LOCATION }}
      
    - name: Publish for Windows
      run: dotnet publish ${{ env.PROJECT_LOCATION }} --configuration Release --runtime win-x64 --self-contained false --output ./publish
      
    - name: Upload build artifacts
      uses: actions/upload-artifact@v4
      with:
        name: windows-app
        path: ./publish/

  deploy:
    needs: build
    runs-on: windows-latest
    if: github.ref == 'refs/heads/main' && github.event_name == 'push'
    
    steps:
    - name: Download build artifacts
      uses: actions/download-artifact@v4
      with:
        name: windows-app
        path: ./deploy/
        
    - name: Deploy to Windows Server
      run: |
        echo "Deploying to Windows server..."
        
    - name: Setup MSDeploy
      run: |
        choco install webdeploy -y
        $env:MSDEPLOY_PATH = "C:\Program Files\IIS\Microsoft Web Deploy V3"
        $env:PATH += ";$env:MSDEPLOY_PATH"

    - name: Deploy to IIS
      run: |
        "& 'C:\Program Files\IIS\Microsoft Web Deploy V3\msdeploy.exe' -verb:sync -source:contentPath='./deploy' -dest:contentPath='Default Web Site/westsidesoftware.com',computerName='myservice.ip',username='${{ secrets.DEPLOY_USERNAME }}',password='${{ secrets.DEPLOY_PASSWORD }}'"        
        
        Write-Output "Deployment completed successfully!"

To improve a GitHub Action generated by Copilot, you can:

Review the logic carefully – Copilot suggestions may not cover all edge cases.
Add error handling (e.g., continue-on-error, if conditions).
Use caching (actions/cache) to improve performance.
Pin action versions (avoid @main or @latest) for stability and security.
Add comments to make the workflow easier to understand.
Test locally or in a test branch before merging into production.
Optimize triggers (on:) to avoid unnecessary runs.
