Executing same request from C# VS SSMS give different execution time

Is this consistent, time after time?

I see a CPU difference which could be compile time. Are there any LINQ settings that affect this?

Edit:

• Capture the plans in Profiler
• Are you sure the SQL is the same in Profiler?

I think that the problem is in the EDMX file use to generate queries from the C# app.

I found those links that explain the case.

You will want to look at the Execution plans for the two queries and see where they are different.
