How can I get the clickonce build script used by visual studio to publish my application

I have a pretty large multi-project solution. I currently build it in Visual Studio, and then publish using the right-click=> publish option. This works very well.

I am now in the position where I need to automate at least the clickonce publishing beyond what I can do in Visual Studio. I have successfully created a publish.xml file which I can use with msbuild and mage to create something that looks like a clickonce. However, there is a lot of complexity in the config I have in the visual studio interface that I would like to simply be able to copy into my publish.xml file.

Is it possible to get visual studio to generate a file that provides the properties used by MSBuild and/or Mage when visual studio publishes from the right click=> publish process?

Basically, I would like a configuration file that I could use to do something like msbuild publish.xml (or similar) and get exactly the publish result that visual studio makes.

I currently use VS2017. The application is winforms using c#

Here is my publish.xml. It is not supposed to be anything beyond a test

<Project> 
    <PropertyGroup>
        <OutputPathBuild>C:\Users\d_000\Documents\Visual Studio 2017\Projects\CP\CP.UI.Winforms\bin\x86\Debug</OutputPathBuild>
        <Version>1.0.0.0</Version>
        <OutputPathDeployment>C:\Users\d_000\Documents\CP Deploy\test</OutputPathDeployment>
        <Mage>C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.1 Tools\mage.EXE</Mage>
    </PropertyGroup>
  <Target Name="Deployment">
    <Error Condition="'$(Version)'==''" Text="The Version property must be defined in order to build the Deployment task."/>

    <ItemGroup>
      <DeploySource Include="$(OutputPathBuild)\**"/>
    </ItemGroup>
    <Copy SourceFiles="@(DeploySource)" DestinationFolder="$(OutputPathDeployment)\v$(Version)\%(RecursiveDir)"/>
    <Exec Command='"$(Mage)" -New Application -ToFile "$(OutputPathDeployment)\v$(Version)\MyApp.manifest" -Name MyApp -Version $(Version) -Processor X86 -FromDirectory "$(OutputPathDeployment)\v$(Version)" -IconFile Resources\CPIcon.ico'/>
    <Exec Command='"$(Mage)" -New Deployment -ToFile "$(OutputPathDeployment)\MyApp.application" -Name MyApp -Version $(Version) -Processor X86 -AppManifest "$(OutputPathDeployment)\v$(Version)\MyApp.manifest" -IncludeProviderURL true -ProviderURL "http://example.com/download/MyApp/MyApp.application" -Install true'/>
    <!-- Grr... Mage tool has a bug whereby -MinVersion only works in Update mode... -->
    <Exec Command='"$(Mage)" -Update "$(OutputPathDeployment)\MyApp.application" -MinVersion $(Version)'/>
    <Copy SourceFiles="$(OutputPathDeployment)\MyApp.application" DestinationFiles="$(OutputPathDeployment)\MyApp.v$(Version).application"/>
  </Target>
  </Project>

EDIT:

I need to customize what is in the publish process, so I am looking to find out what Visual Studio is doing. Essentially I want to get the commands run in visual studio, copy them and tweak them so I can automate several different builds with different delpoy URLs and update URLs
