Execute .bat file at end of VS2017 Asp.Net Core publish action?

In Visual Studio 2017 when publishing an Asp.Net Core Website using the File System publish method I want to trigger the execution of a .bat file after the publish operation copied the files to the output directory.

I have learned that the settings for the publish operation are stored by Visual Studio in the project's Properties/PublishProviles directory in a .pubxml file. So in may case the file is FolderProfile.pubxml and it currently looks like this:

    <?xml version="1.0" encoding="utf-8"?>
    <!--
    This file is used by the publish/package process of your Web project. You can customize the behavior of this process

    -->
    <Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
      <PropertyGroup>
        <WebPublishMethod>FileSystem</WebPublishMethod>
        <PublishProvider>FileSystem</PublishProvider>
        <LastUsedBuildConfiguration>Release</LastUsedBuildConfiguration>
        <LastUsedPlatform>Any CPU</LastUsedPlatform>
        <SiteUrlToLaunchAfterPublish />
        <LaunchSiteAfterPublish>False</LaunchSiteAfterPublish>
        <ExcludeApp_Data>False</ExcludeApp_Data>
        <PublishFramework>net461</PublishFramework>
        <ProjectGuid>f58b5ca0-8221-4c97-aa6d-7fba93a3abeb</ProjectGuid>
        <publishUrl>C:\inetpub\wwwGiftOasisResponsivePublished</publishUrl>
        <DeleteExistingFiles>True</DeleteExistingFiles>
      </PropertyGroup>
    </Project>

Based on the comments in the .pubxml file and additional research, it's my understanding this file is essentially an msbuild file and ultimately msbuild is used to perform the publish operation. msbuild files seem very flexible but more than a little complicated. I'm really struggling with this one.

If I had a batch file in the root of my project called finishPub.bat, how could I modify the above .pubxml file to cause the execute of the finishPub.bat file after the website has been copied to the output folder?

You can amend your publish profile with a custom target:

<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    <WebPublishMethod>FileSystem</WebPublishMethod>
    ...
  </PropertyGroup>
  <Target Name="ExecuteBatAfterPublish" AfterTargets="AfterPublish">
    <Exec Command="example.bat" WorkingDirectory="$(publishUrl)" />
  </Target>
</Project>
