Generic logger (ARCH1011)

Key dotnet.logging.generic-logger · Severity warning · Category logging

The non-generic ILogger does not derive its category from the type name, which makes filtering logs by source class harder. Use ILogger<T>.

Incorrect

public OrderService(ILogger logger)
{
    _logger = logger;
}

Correct

public OrderService(ILogger<OrderService> logger)
{
    _logger = logger;
}

Fix

Change the dependency to ILogger<T>, where T is the class using the logger, so the category is assigned automatically.
