title: Unable to debug in-process web project (ASP.NET Core Module)
body: <p>I'm experimenting with the <strong>ASP.NET Core Module</strong> introduced in ASP.NET Core v2.2.0, specifically the in-process hosting. I am able to get it to work in production, but while developing, Visual Studio warns me that breakpoints won't be hit because no symbols have been loaded for the document.<br>
  I suspect this has to do with the in-process mode, Visual Studio doesn't know how to attach itself to the service (<code>w3wp.exe</code>).</p>
  
  <p>Does anyone know what I'm missing? As soon as I switch to out-of-process hosting, the breakpoints work as they should.</p>
