Implicit/Explicit conversion with respect to the “as” keyword

Question

I\'m trying to do some unit testing on a project that unfortunately has high level of unit interdependence. Currently, a lot of our classes look to a custom UserId

Answer 1

So, why don't you use an explicit cast?

// will throw if cast fails
internal static UserIdentity GetCurrentIdentity()
{
    UserIdentity currentIdentity = (UserIdentity) ApplicationContext.User.Identity ;
    return currentIdentity;
}

This ought to trigger your explicit operator. You can test with is first to make it safer.
