Implement steps outlined in hangfire documentation.

Step 5b is only necessary when a website contains several child-applications and one wants to start a specific one. Otherwise, steps 1-5b suffice.

Step 5 is persisted in the web.config of your application. To make sure it's not overwritten on deployment, I'd put a web.config with the respective configuration under source control.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.webServer>
    <handlers>
      <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
    </handlers>
    <aspNetCore processPath="%LAUNCHER_PATH%" arguments="%LAUNCHER_ARGS%" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="inprocess" />

    <!-- Add this node to web.config -->
    <applicationInitialization doAppInitAfterRestart="true">

      <!-- Only needed when website contains multiple child apps -->
      <add initializationPage='/hangfire',hostname='' />

    <applicationInitialization />
  </system.webServer>
</configuration>

The Azure DevOps Pipelines deploy task uses Web Deploy, which in turn uses the app_offline.htm during deployment. After the app_offline.htm is removed, only the next request restarts the app. So you if you use the app_offline.htm directly or indirectly, you need to fire a warm-up request manually. You can use a more elaborate warm-up script or this one-liner in your deployment pipeline.
