Entity retrieval into an entity collection object > Using a query High-level APIs and Low-level API are listed.

Why is the High-level APIs recommended?

Best regards Morten

The goal for the QuerySpec API is to make it easier to use our native Query API by using a fluent interface which mimics the SQL query to produce. This is close to the native query api which embodies the SQL query fragments at a lower level.

Plus query spec / linq get features that aren't necessarily added to the low-level API, like resultset caching.

Thanks for your explanations
