ILogger<T> not logging when T is another project

[SinghManvir]

I can see all logs in my functions class but it does not seem to be logging anything from another class in another project.

I have tried all suggestions in issue 4345 and issue 4425.

So, I have tried adding the filter like

services.AddLogging(loggingBuilder =>
{
     loggingBuilder.SetMinimumLevel(LogLevel.Debug);
     loggingBuilder.AddFilter(typeof(Service1).FullName, LogLevel.Debug);
});

and also tried in host.json

"logLevel": {
   // For all functions
   "Function": "Debug",
   "X.Domain.Suppliers.Service1": "Information",
}

and tried the solution name as well like

"logLevel": {
   // For all functions
   "Function": "Debug",
   "X-API": "Information",
}

I am running this locally with Core Tools Version: 3.0.3160, Function Runtime Version: 3.0.14916.0

@SinghManvir Are you looking to see these logs in the console? Can you please try to run func with the --verbose flag? Also would be great to know if the logs are missing in Application Insights in production as well?

Also, can you try setting the default log level to Information?

"logLevel": {
   "default": "Information"
}

[SinghManvir]

Yes, I am trying to see the logs in the console, but they are also missing in App Insights in Production.
I have had "default": "Information", only took it out to see if that made a change.

I will try running the function with verbose flag.

@anthonychu - Tried adding start --verbose to the Application arguments in project properties and no luck.
In case it helps, I can see my service listed in the Logger Filter Options

@pragnagopa @brettsam Do you have any thoughts?

[pragnagopa]

As the logs are missing from AppInsights as well, this looks related to #4345
I will transfer this issue to host as issue is not related to Core-Tools.
