I have ASP.NET Core 2.1 project which uses a class library built on .Net Core 2.1. In .Net Core 2.1 class library i need to make several REST class,for which i am using HttpClient class.

I want to leverage the benefits of HttpClientFactory for creating and using HttpClient instances.

How can i use HttpClientFactory in .Net Core 2.1 class library.

  • Are you certain that you actually need to use HttpClientFactory? If the class library you're using only creates a few, long-lived instances of HttpClient then you don't need to use HttpClientFactory. If you do need to use it, then you would pass it in as a DI parameter to some "service" class object instance instantiated in ASP.NET Core's own DI container. Commented Mar 8, 2019 at 7:26
  • Idea to use HttpClientFactory was to make use of the functionality available for Retry and Fault Handling. Commented Mar 8, 2019 at 8:33
  • The http instances used in class libraries are not long lived,and i need to make call to different rest endpoints often. Commented Mar 8, 2019 at 8:37
