About

This package provides an HttpMessageHandler implementation backed by Windows HTTP Services (WinHTTP). While the use of the default HttpClientHandler is highly recommended for applications targeting modern .NET, WinHttpHandler might help migration scenarios by providing an alternative HTTP backend for Windows that works consistently accross .NET Framework and modern .NET.

Key Features

  • Enables sending asynchronous HTTP requests with HttpClient on Windows.
  • Handles authentication and credentials.
  • Exposes a subset of WinHTTP options as C# properties on WinHttpHandler.
  • Use custom proxy.
  • Handle cookies.

How to Use

using System.Net;

using WinHttpHandler handler = new()
{
    ServerCredentials = new NetworkCredential("usr", "pwd")
};

using HttpClient client = new(handler);
using HttpRequestMessage request = new(HttpMethod.Get, "https://httpbin.org/basic-auth/usr/pwd");
using HttpResponseMessage response = await client.SendAsync(request);

Console.WriteLine($"Status: {response.StatusCode}");
if (response.IsSuccessStatusCode)
{
    string content = await response.Content.ReadAsStringAsync();
    Console.WriteLine(content);
}
