This code relies on the following NuGet packages:
EntityFramework.SqlServer
Microsoft.Framework.Logging.Console

@tonysneed Is this still valid?

@ErikEJ

var service = ((IAccessor<IServiceProvider>)context).Service;
var loggerFactory = service.GetRequiredService<ILoggerFactory>();
loggerFactory.AddConsole(LogLevel.Verbose);

Thanks @nbalakin and @tonysneed, it works.

@nbalakin the logger factory instance is shared across multiple DbContexts and thus everytime I call this code, another logger is added. As a result, provided I call this code when creating a new DbContext, after 5 DbContexts have been created during the application lifetime, all SQL queries are logged five times.

Am I doing anything wrong? Where exactly should this be called?

I have the same question, where should this code go? Thanks.

This worked for me with EF7 rc2-16485:

    "EntityFramework.MicrosoftSqlServer": "7.0.0-rc2-16485",
    "Microsoft.Extensions.Logging.Console": "1.0.0-rc2-15888",

    public static class DbContextExtensions
    {
        public static void LogToConsole(this DbContext context)
        {
            var contextServices = ((IInfrastructure<IServiceProvider>) context).Instance;
            var loggerFactory = contextServices.GetRequiredService<ILoggerFactory>();
            loggerFactory.AddConsole(LogLevel.Verbose);
        }
    }

Where is the RTM Version?

oh,It doesn't work.
