How to add COM references in ASP.NET mvc 6 and Visual Studio 2015?

问题

I can do that in Visual Studio 2012 w/o problems, but not in 2015 with MVC 6, pic related:

Is it even possible?

I find your question interesting. DotNet application access to COM via interop assembly which can be generated with respect of tlbimp.exe for example. Typically you have already generated a lot of such intreops. You can see there in %SystemRoot%\assembly\GAC_MSIL directory. For example I have Office installed on my computer. I will show below how to create small ASP.NET 5 project which starts Microsoft Word using the COM interface.

I created simple Console Application, have removed "dnxcore50" part from "frameworks". Then I selected "References" in the Solution Explorer, clicked right mouse and chosen "Add Reference...". Now I clicked "Browse..." button

navigated to C:\Windows\assembly\GAC_MSIL\Microsoft.Office.Interop.Word\15.0.0.0__71e9bce111e9429c, chosen Microsoft.Office.Interop.Word.dll and clicked "Add" button. After that, I could see the following view in Solution explorer:

It's important to mention, that global.json was modified and "wrap" directory was included in "projects" part. The folders wrap and lib was created in the solution

The folder lib\dnx451 contains the copy of Microsoft.Office.Interop.Word.dll. Additional project.json was created in wrap\Microsoft.Office.Interop.Word folder with the following content:

{
  "version": "1.0.0-*",
  "frameworks": {
    "dnx451": {
      "bin": {
        "assembly": "../../lib/dnx451/Microsoft.Office.Interop.Word.dll"
      }
    }
  }
}

and the main project.json contains now

{
  "frameworks": {
    "dnx451": {
      "dependencies": {
        "Microsoft.Office.Interop.Word": "1.0.0-*"
      }
    }
  }
}

I created the simple program which starts Microsoft Word and makes it visible:

namespace OldConsoleAppCom
{
    public class Program
    {
        public static void Main(string[] args)
        {
            var wordApp = new Microsoft.Office.Interop.Word.Application();
            wordApp.Visible = true;
        }
    }
}

One can compile such application and successfully run.
