Can I use HttpClientFactory in a .NET.core app which is not ASP.NET Core?

Question

I have read the popular blog post https://www.stevejgordon.co.uk/introduction-to-httpclientfactory-aspnetcore on using HttpClientFactory

To quote from it

As one of the answers suggests,

you do not need ASP.NET to use it

However, you need a bit of work to get it into your Dependency Injection (DI):

• Install microsoft.extensions.http (has nothing to do with ASP.NET)

• When configuring your DI, use this extension. it registers builders/httpclientFactory/... (have a look at its source code on github)

  ServiceCollections.AddHttpClient();
  

• if you want register HttpClient with different names/settings to communicate with different web servers (different settings, ex: different base urls)

  ServiceCollection.AddHttpClient(
  "yourClientName", x => x.BaseAddress = new Uri("http://www.mywebserver.com"))
  

• In case you want to add DelegateHendlers, you need to add it both to your httpClient and your DI container.

  ServiceCollection
          .AddHttpClient(clientName, x => x.BaseAddress = new Uri("http://www.google.com"))
          .AddHttpMessageHandler();
  ServiceCollection.AddScoped();
  

• register your HttpClient to use HttpClientFactory

  ServiceCollection.AddScoped(x => 
  x.GetService().CreateClient("yourClientName"));
  

• To resolve http client:

  var client = ServiceProvider.GetService();
