API documentation not getting generated from docfx 2.17.2

Title

docfx not generating API documentation either from docfx.json or directly using the csproj file option in docfx metadata command. Using docfx 2.17.2 console version

Functional impact

Unable to generate the API documentation

Minimal repro steps

Created a .NET core console app with one class Program.cs with a /// comment

namespace ConsoleApp2
{
/// <summary>
/// This is a line for testing Docfx
/// </summary>
    class Program
    {/// <summary>
    /// Main Mehod
    /// </summary>
    /// <param name="args"></param>
        static void Main(string[] args)
        {
            Console.WriteLine("Hello World!");
        }
    }
}

Added a docfx.Json file under the same directory as csproj file

{"metadata": [
    {
      "src": [
        {
          "files": [
            "*.csproj"
          ],
          "exclude": [
            "**/bin/**",
            "**/obj/**",
            "_site/**"
          ]
        }
      ],
      "dest": "api",
	"properties": {
                "TargetFramework": "netcoreapp1.1"
            }
    }
  ]
}

Ran docfx metadata in the same directory

Expected result

API documentation to be generated

Actual result

No documentation generated instead getting a message “No metadata is generated for ConsoleApp2”

Hi, made the class public and the Meta data was generated. Thanks for the help

Exactly my problem… I got sidetracked with solutions for previous metadata bugs (i.e. install VS 2015 build tools).
