  <p>As for your release script, you are forgetting to pass in the values so your release script isn't doing anything at the moment.
  But when it does work, it will take the objects from your artifacts or container images and deploy them into your webapp the same way it would do it if you ran those commands from your local machine.</p>

Answers: Hi thanks for the answer - what is the difference between `DotNetCoreCLI@2 Publish` and `PublishBuildArtifacts@1`. Also, there is nothing in  "Artifacts" in Azure Devops... I don't know why - or where the release pipeline gets the files it needs from as it is working - the release is successful - I have a site I can navigate to.

Answers: You probably don't have any artifacts getting built, so you don't see the difference. Publish is creating the docker image and pushing it. Build artifacts would be creating artifacts and putting them into the artifacts section if there were any artifacts to build.

Answers: <p>First to answer the difference between DotNetCoreCLI@2 Publish and PublishBuildArtifacts@1</p>
  <p>In DotNetCoreCLI@2 Publish task you are only publishing your build output\ files built by your code to $(Build.ArtifactStagingDirectory) which is a predefined variable for the build artifact location. This need not even be $(Build.ArtifactStagingDirectory). Here you are just telling the build pipeline where to place the files built from your code.</p>
  <p>In PublishBuildArtifacts@1 task, it lets you publish your $(Build.ArtifactStagingDirectory) or your built binaries (if generated elsewhere) or even your source code to a file share or Azure pipelines. Basically PublishBuildArtifacts@1 is also what defines the content or artifact that gets passed to your release pipleline from your build pipeline.</p>

Having said that, I've managed to create a build pipeline that runs tests and published my project, then I created a release pipeline and have successfully released to an Azure App Service.

  First to answer the difference between DotNetCoreCLI@2 Publish and PublishBuildArtifacts@1
  
  In DotNetCoreCLI@2 Publish task you are only publishing your build output\ files built by your code to $(Build.ArtifactStagingDirectory) which is a predefined variable for the build artifact location. This need not even be $(Build.ArtifactStagingDirectory). Here you are just telling the build pipeline where to place the files built from your code.
  
  In PublishBuildArtifacts@1 task, it lets you publish your $(Build.ArtifactStagingDirectory) or your built binaries (if generated elsewhere) or even your source code to a file share or Azure pipelines. Basically PublishBuildArtifacts@1 is also what defines the content or artifact that gets passed to your release pipleline from your build pipeline.
