title: Azure App Service and .Net Framework versions
body: <p>I have an Asp.Net Web API set to target .NET 4.6.1 which is published to an Azure App Service.</p>
  <p>I received a <a href="https://github.com/jeffwmartinez/appservicedotnetframework.github.io#net-framework-48-is-coming-to-app-service" rel="nofollow noreferrer">notification</a> from Microsoft about the imminent move to .NET 4.8 for Azure App Service.</p>
  <p>The notification recommends I test my applications locally.</p>
  <p>I can see that v4.6.1 is an installed version of .NET framework for my Azure App Service:</p>

  <p>Two questions:</p>
  <ol>
  <li>Given v4.6.1 exists will my Web API continue to use v4.6.1 regardless of the later versions of .NET framework that are present?</li>
  <li>What (if any) testing is needed prior to the v4.8 App Service Update? Is it just a case of building it locally using v4.8 to confirm it builds/runs, or is a thorough batch of regression testing warranted?</li>
  </ol>
