title: System.Web.ApplicationServices in .NET Core 2
body: <p>I'm building a Web API in .NET Core 2. I'm using some custom nuget packages to leverage their built in functionality. These custom packages were built against an older .NET version (4.6.1). The problem is some of these packages have references to the old System.Web dll. I'm getting this warning on some of the custom packages in the solution</p>
  
  <p>package was restored using '.net framework version=v4.6.1 instead of using the proj target framework.</p>
  
  <p>The app is also throwing this exception below when I call code in one of the custom packages </p>
  
  <p>System.IO.FileNotFoundException: Could not load file or assembly System.Web.ApplicationServices, Version=4.0.0.0, Culture=neutral,The system cannot find the file specified</p>
  
  <p>Is there any way around this other than re-writing the code in my web Api?</p>
