Profile Entity Framework queries?

Hi!
I want to see SQL request generated by LINQ. I've seen that some people use a "datacontext.Log = Console.Output", but I don't have a .Log on my datacontext.

So, how to do this? For me if there is an equivalent to Console.Output, it resolves my problem

(I'm using entity framework 4.0 and POCO object).

Thank you for the help

Hi Nargzul;

In the Entity Framework there is no Log function in the ObjectContext as there is in Linq to SQL in the DataContext. You have two options that I know of, first is to use SQL Profiler on the server and look at the SQL command comming into the server, Second is to build a EFTracingProvider, the two links below is the EFTracingProvider lib code and the second link is a small sample showing how to implement one.
