Referencing a Generic member without a generic

[TonyValenti]

I have code that looks something like this (simplified):

public class ImportJobMembers {
    public string M1 { get; set; }
}

public abstract class ImportJob {
    public long P1 { get; set; }
}

public class ImportJob<T> : ImportJob where T : ImportJobMembers, new() {
    public T Original {get; set; }
    public T Final {get; set; } 
}

public class MatterImportJobMembers : ImportJobMembers {
    public string M2 { get; set; }
}

public class MatterImportJob : ImportJob<MatterImportJobMembers> { }

I want to change my code to be something like this:

public abstract class ImportJob {
    public long P1 { get; set; }
    public abstract ImportJobMembers Original {get; set;}
    public abstract ImportJobMembers Final {get; set;}
}

public class ImportJob<T> : ImportJob where T : ImportJobMembers, new() {
    public override T Original {get; set; }
    public override T Final {get; set; } 
}

So I can always reference Final.M1 with from a non-generic ImportJob.

How can I do that? Is this even possible?

You can reference M1 directly through InputJobMembers. No generics are needed.

What you can't do is have Original and Final be contravariant overrides on ImportJob<T> as that would break type safety.
