哪种查询最适合在Entity Framework中针对概念模型进行查询？

Question

There are 3 way for querying against conceptual model in EF :

1. LINQ to Entity
2. Entity SQL
3. Query Builder Methods

Which one is better for which situation? Is there any performance issues for these 3 type of querying?

Answer 1

In general, all these ways are appropriate for production.
In case you plan to reuse the LINQ to Entities query use CompiledQuery. There is a number of performance peculiarities in Entity Framework - take a look at this MSDN article .
