Failed to create Type.GetType (string TypeName) method and MemberInfo.CustomAttributes property available in DNX Core 5.0

I'm trying to get controller attributes and controller methods, but I can't seem to imagine the required methods and properties available in DNX Core 5.0. I want to get what roles a user should get to access a given method. For example, if I have this

 [Authorize(Roles = "Admin")]
 public class UserController : Controller
 {
    public IActionResult Index()
    {
        return View();
    }
}

I want the user to be able to get the admin role in order to have access to this controller. My project.json file for dnxcore50 looks like this:

"dnxcore50": {
  "dependencies": {
    "System.Collections": "4.0.10-beta-*",
    "System.Collections.Concurrent": "4.0.10-beta-*",
    "System.IO": "4.0.10-beta-*",
    "System.Linq": "4.0.0-beta-*",
    "System.Linq.Expressions": "4.0.10-beta-*",
    "System.Reflection": "4.0.10-beta-*",
    "System.Reflection.Emit": "4.0.0-beta-*",
    "System.Reflection.Emit.Lightweight": "4.0.0-beta-*",
    "System.Reflection.Extensions": "4.0.0-beta-*",
    "System.Reflection.TypeExtensions": "4.0.0-beta-*",
    "System.Reflection.Primitives": "4.0.0-beta-*",
    "System.Runtime": "4.0.20-*",
    "System.Runtime.Extensions": "4.0.10-beta-*",
    "System.Runtime.CompilerServices.VisualC": "4.0.0-beta-*",
    "System.Runtime.InteropServices": "4.0.20-beta-*",
    "System.Text.Encoding": "4.0.10-beta-*",
    "System.Text.RegularExpressions": "4.0.10-beta-*",
    "System.Threading": "4.0.10-beta-*"
  }
}

Any ideas on how I would get the required methods / properties to access in DNX Core 5.0, or any other suggestions on how to approach this issue?

If you look at the github source code, you can see how it is parsed (line 94):

https://github.com/aspnet/Mvc/blob/eef6c3883a7e27b8387b0925f0b6a88df0a484c5/src/Microsoft.AspNet.Mvc.Core/ModelBinding/Metadata/ModelAttributes.cs



As you can see, you must use GetTypeInfo () to use the GetCustomAttributes () method. In code, you can:

using System.Reflection;
...
obj.GetType().GetTypeInfo().GetCustomAttributes();
