Entity Framework DbContext: entities configured everytime?
===

I'd like to know if Entity Framework `System.Data.Entity.DbContext` gets configured each time it's instantiated.

_Why I got this question?_

For example, if you're doing manual mappings overriding `DbContext.OnModelCreating(...)` method, it seems that this is going to be called each time a `DbContext` is instantiated.

**Does Entity Framework perform some kind of configuration caching or whatever?**

Thank you.
