WARNING: Since version 3.0.0, each Include will cause an additional JOIN to be added to SQL queries produced by relational providers, whereas previous versions generated additional SQL queries. This can significantly change the performance of your queries, for better or worse. In particular, LINQ queries with an exceedingly high number of Include operators may need to be broken down into multiple separate LINQ queries in order to avoid the cartesian explosion problem.
