title: HTTP Error 500.32 - ANCM Failed to Load dll after deploying a Self Contained .Net Core 3.1 App to Azure
body: <p>I have an Asp .NET Core 3.1 App which is deployed to Azure App Service (West Europe/Windows based). When I use a Framework dependendant Deployment Mode, the app is starting smoothly. </p>
  
  <p>But, when I try to switch to a Self Contained deployment, the App fails to start and I get an error message : <em>HTTP Error 500.30 - ANCM In-Process Start Failure</em></p>
  
  <p>Changing the Runtime from win-x86 to x64 didn't solve the problem. </p>
  
  <p>I inspected the App Server runtime versions installed and it looks like runtimes are available (cf. screenshot below). </p>
  
  <p>What am I doing wrong? </p>
