c# - Log Queries executed by Entity Framework DbContext

Question

I'm using EF 6.0 with LINQ in MVC 5 project. I want to log all the SQL queries executed by the Entity Framework DbContext for debugging/performance-measurement purpose.

In Java/Hibernate, equivalent behavior can be achieved by setting the property hibernate.show_sql=true. Is it possible to have a similar behavior in Entity Framework?

Logging and Intercepting Database Operations article at MSDN is what your are looking for.

The DbContext.Database.Log property can be set to a delegate for any method that takes a string. Most commonly it is used with any TextWriter by setting it to the “Write” method of that TextWriter. All SQL generated by the current context will be logged to that writer. For example, the following code will log SQL to the console:

using (var context = new BlogContext())
{
    context.Database.Log = Console.Write;

    // Your code here...
}
