Enable raw SQL logging in Entity Framework Core

Question

How do I enable the logging of DbCommand raw SQL queries?

I have added the following code to my Startup.cs file, but do not see any log entries from the Entity Frame

Answer 1

Figured it out - need to configure DbContext to use logger factory.

protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
    base.OnConfiguring(optionsBuilder);

    optionsBuilder.UseLoggerFactory(_loggerFactory);
}

From MVC Core 2, logging SQL is the default behaviour. Just make sure logging level in appSettings json file is correct.

"Logging": {
  "LogLevel": {
    "Default": "Debug",
    "System": "Information",
    "Microsoft": "Information"
  }
}
