title: How do I implement IHttpClientFactory in .net framework apart from .Net core?
body: <p>In .Net core, we can use IHttpClientFactory to inject and use during runtime. As a developer I no need to worry about the dependency resolution. I need to just specify AddHttpClient() in service collection.
  Likewise, how can I use IHttpClientFactory in WPF application, .net framework 4.6.1? As there is no Service collection available for WPF application, not getting how to resolve the dependency.</p>
