Inject attribute doesn't work for field

问题

Inject attribute is not working for field.

[Inject]
public MyContext context; //Not injected

[Inject]
public MyContext context {get; set;} //Injected

I am using default Ninject settings. Why field is not injected ?

回答1:

Because it is not allowed.

From the Ninject 2 Beta announcement:

Things that were in Ninject 1.x that are not in Ninject 2:

• Field injection: Ninject 2’s injection is now driven by expression trees, and in .NET 3.5 there is no way to set field values with an expression tree. Since this is a bad practice anyway, I decided to cut it.
