For Linq to Sql queries, you may get this warning. The lambda's scope may outlive the method due to the fact that the query is often actualized after the method is out of scope. Depending on your situation, you may want to actualize the results (i.e. via .ToList()) within the method to allow for GC on the method's instance vars captured in the L2S lambda.
