• Making linq avoid using in memory filtering where possible

• How does linq decide between inner & outer joins

  - by user287795

  Hi Usually linq is using an left outer join for its queries but on some cases it decides to use inner join instead. I have a situation where that decision results in wrong results since the second table doesn't always have suitable records and that removes the records from the first table.
