Do I need to force a Dispose after a LINQ query?

Question

My DBA says that there are way too many connection open and he thinks it is my code in .net that is leaving them open.

I am using LINQ querys and EF code first.

Answer 1

The entity framework uses, as far as i know, connection pooling by default to reduce the overhead of creating new connections everytime. Are the connections closed when you close your application?

If so, you could try to decrease the Max Pool Size in your connection string or disable connection pooling entirely. See here for a reference of possible options in your connection string.
