This feature is at least partially implemented in EF Core 2.1. There is no custom binding but many additional patterns are now supported by convention, including injecting the property values in the constructor, injecting instances of services also in the constructor and on properties.
Direct mapping to fields was already supported in 1.1.Adam Churvis commented
Requiring default constructors and publicly-accessible properties when using EF is my Public Enemy Number One. Parameterized constructors, definitely.
