描述

In the section on Including multiple levels it says "This does not mean you will get redundant joins". Then just below the example it says "Since version 3.0.0, each Include will cause an additional JOIN to be added". It's not clear whether the warning only applies where you are including different entities or whether it applies even when you are including the same entity more than once as in the example

研究方向
Examine the file entity framework/core/querying/related data.md, specifically the section 'Including multiple levels'. The two statements mentioned need to be compared to understand their different contexts. Review the example below the statement about version 3.0.0. Provide a clarification that distinguishes the warning about redundant joins from the behavior change about additional JOINs.
