Is it possible to use QueryView with EF Code-First?

Question

The title should be self explanatory. QueryView in EDMX allows predefined projections and conditional queries. QueryView creates additional readonly mapping.

Example:

Suppose that we have BlogPost table which has Title, ShortDescription and Content columns. If we want to use BlogPost we will use directly this entity. If we want to show list of recent BlogPosts showing only titles and descriptions we will not want to load contents as well. One way is to use query with projection directly. Other way is to map this projection in EDMX (by using QueryView = reusable projection is part of your mapping) to new entity called BlogPostInfo. Then you can query your context for BlogPostInfo entities when showing list of blog posts.

Answer 1

I found that it is possilbe to use QueryView if DbContext is generated from EDMX because in such case DbContext only wrapps mapping in EDMX. But it is not what I was looking for. Code first itself probably doesn't offer any QueryView equivalent so the best way is probably define reusable projection queries as methods directly on derived DbContext implementation.
