aspnetcoreautofacissuerepro

An ASP.NET core app that repros and issue I'm facing with AddHttpClient and Autofac

The setup:

• HomeController that depends on ILogger and IClient
• ILogger that depends on an integer logger ID that is injected per request. This is registered with InstancePerLifetimeScope
• IClient that depends on HttpClient and ILogger. This is registered with ASP.NET Core's AddHttpClient

The issue: While IClient is instantiated once per request (can verify by putting breakpoint in its constructor), the ILogger injected into it is the same for each request. I would expect it to be a new ILogger per request since I registered it with InstancePerLifetimeScope.

This can be seen by refreshing the page multiple times and looking at the console logs. For each request, you will see the same log

Logger id: 2. => from Client

along with a "from HomeController" log with incrementing logger id. This shows that a new ILogger is injected into HomeController each request, but the same ILogger is injected into Client.

To run the project, open in Visual Studio 2017 (probably works in other versions too) and Run the WebApplication2 project.
