linq - .AsExpandable in Linq to Entity

Question

在 Linq to Entity 中，.AsExpandable() 做什么？到底怎么办？在哪里以及为什么使用它？它是否将所有相关实体都包含在查询中以进行延迟加载？

Answer 1

Entity Framework's query processing pipeline cannot handle invocation expressions, which is why you need to call AsExpandable on the first object in the query. By calling AsExpandable, you activate LINQKit's expression visitor class which substitutes invocation expressions with simpler constructs that Entity Framework can understand.
