| Something about the feature | ||
| This is a small feature that removes a limitation for *expression trees*. Code in expression trees no longer needs to declare arguments for all optional parameters. In addition, code in expression trees can include named arguments. The call rewriting orders named arguments and provides values for missing optional parameters. Query providers shouldn't need to make any adjustments for this support. |

Perhaps this should talk about "code in lambda expressions that are converted to expression trees" for clarity?
