title: Adding Class Libraries to Solution - Adding Folders to Web Application
body: <p>I've come across a problem when trying to add multiple .net core class libraries to an already existing .net core web application running on version 1.1. When selecting 'Add > New Project..' and selecting the .Net Core Class Library project type, the class library is added to the solution, but a folder is also created under the web application which I'm finding to be very strange. </p>
  
  <p>If I then go and add another class library, it gets added to the top of the solution which is correct, but another folder is yet again added to the web application. </p>

  <p>As there are now two class library folders in the web application, I get errors telling me that I have duplicate files in my web app project.</p>

  <p>I'm using a start template from this <a href="http://blog.stevensanderson.com/2016/05/02/angular2-react-knockout-apps-on-aspnet-core/" rel="nofollow noreferrer">blog</a> - I'm not sure if this is the cause or not, or whether this is standard behaviour of a .net core application.</p>
  
  <p>Can anybody hazard a guess as to what could be happening here and also let me know if this behaviour is expected?</p>
