How to connect to WSUS server using WSUS remote API from a web API? - windows-update

Question

I am trying to connect to WSUS server remotely from my web application built in ASP.NET Core 2.0. I am using the Microsoft.UpdateServices.Administration.dll to achieve this. I was able to establish successful connection to the server when I built a C# console application and used the same dll file in assembly reference.
I have referred to these similar posts but I have not found an answer yet.

[I am sorry for not maintaining indentation and proper formatting in the sample code.]
Below is the sample code from the console app which worked:
using System;
using System.Reflection;
using Microsoft.UpdateServices.Administration;
namespace WsusRemoteConnectivityConsoleApp
{
class Program
{
static void Main(string[] args)
{
IUpdateServer remoteServer =
AdminProxy.GetUpdateServer("WsusServer1",false,8530);
Console.WriteLine(remoteServer.Name);
}
}
}
The expected output as well as the actual output in the console app is "WsusServer1".
But using the same line of code in the web app, I am not able to connect to the WSUS server. I receive exception saying that "The requested security protocol is not supported" in this line
IUpdateServer remoteServer =
AdminProxy.GetUpdateServer("WsusServer1",false,8530);
Any help is appreciated.
Thanks.

if you have setup SSL, you should use:
AdminProxy.GetUpdateServer("WsusServer1",true,8531);
