title: Add a reference (.Net-Dll) to an ASP.NET 5 / MVC 6 project at compile time
body: <p>I am using Visual Studio Community 2015 RC. I have created an ASP.NET 5 / MVC 6 project.</p>
  
  <p>Now I want to add a (.NET) DLL to the project but if I open the dialog “Add Reference...” I am not able to browse any folders outside the solution. The browse button is missing.</p>
  
  <p>Is there any other way to add a reference to the project at compile time?</p>
  
  <p>A class library (as a NuGet package) is not a solution because here is the same problem. If I create, say, a WPF application the browse button is available.</p>
