How to log queries using Entity Framework 7?

You can log to the console using this code, I am sure it will be wrapped in a simpler api later:

using System;
using Microsoft.Data.Entity.Infrastructure;
using Microsoft.Data.Entity.Utilities;
using Microsoft.Framework.Logging;

public static class SqlCeDbContextExtensions
{
    public static void LogToConsole(this DbContext context)
    {
        var loggerFactory = ((IAccessor<IServiceProvider>)context).GetService<ILoggerFactory>();
        loggerFactory.AddProvider(new DbLoggerProvider());
    }
}

And the DbLoggerProvider is implemented here: https://github.com/ErikEJ/EntityFramework7.SqlServerCompact/tree/master/src/Provider40/Extensions/Logging

For those using EF7 none of the above worked for me. But this is how i got it working. (from @avi cherry's comment)

In your Startup.cs you proably have a Configure method with a bunch of configurations in it. It should look like below (in addition to your stuff).

    public void Configure(IApplicationBuilder app, ILoggerFactory loggerFactory)
    {
        //this is the magic line
        loggerFactory.AddDebug(LogLevel.Debug); // formerly LogLevel.Verbose

        //your other stuff

    }
