ILogger for Controller is not correctly resolved about autofac-serilog-integration HOT 3 OPEN

I've encountered the same problem when trying to use the Autofac serilog integration within an ASP.NET Core 2.1 application - when injecting the ILogger into a Controller, {SourceContext} is blank, but when injecting it into any other class, {SourceContext} works as expected.

2018-10-27 08:56:17.919 INF [] - This is a log line from a controller.
2018-10-27 08:56:17.927 INF [SerilogSample.Test] - This is a log line from a class.

I've put together a basic project that illustrates the problem: @alvaromarithompson/serilog-bug-sample

from autofac-serilog-integration.

Hi @urajkovic - thanks for the report.

I'm not sure how to approach this, I'm not up-to-date with the Autofac integration for ASP.NET Core 2, so would need some time to debug.

Help/PRs welcome, if anyone's able to take a look.

Thanks again!

The reason for this is something that we already explained. While controller’s constructor dependencies would be resolved by MVC from the IServiceProvider (so in our case an Autofac adapter), the instance of the controller itself (and its disposal too) is created and owned by the framework, not by the container.

The quickest workaround is to AddControllersAsServices in the configure services method
