So which method is better?

A a = new A();

interface1 a = Create()

So is it correct to have 'ModulesPath' of type IList or List?

So here, should 'i' be of type IIAD or of type InstrumentDomain i.e. the concrete class?

public IList<T>
F<T>
(
)
{
    List<T> result = new List<T>() ;
...
    return ( result.AsReadOnly() ) ;
}
