Trace SQL Query in EF Code First

I'm using E开发者_如何学运维ntity Framework Code First and I'd like to be able to record all the SQL queries generated by the DbContext. In Linq to sql there was a DB log and I can't seem to find it in EF. I could then drop them in a log or output it to the page.

I'm using the version 4.1.0.0 of the EntityFramework Assembly.

Your best bet would be to use the Entity Framework Profiler, although it's unfortunately not free.

You can also manually get the SQL it will generate by running a ToString() on the IQueryable itself, but that will have to be done on a per-query basis.

One final option is that if you are using MS Sql Server as your backend, you can load up the Sql Server Profiler (that comes with Sql Server Management Studio I believe) and log the sql statements from there.

Miniprofiler a free alternative to entity framework profiler that will allow you to trace all sql queries made during web requests

With tools like EF it becomes more important than ever to use the SQL Server Profiler, and it should be the primary tool used for this type of situations, if it was important when we actually wrote the queries it is even more important now that these tools build the queries for us, it's a must not only for debugging but also for optimization

I'll just leave it here.

public class Context : DbContext
{
    public Context(string connectionString) : base(connectionString)
    { Database.Log = Console.Write;  }
}
