"Are there any simple groups that appear as zeros of the zeta function?" by Peter Freyd; why is this consternating to mathematicians?

Found this thread while I was looking for a solution to the exact problem described in the original post. None of the answers met my situation entirely, however. Brody's answer was pretty close. Here is my situation and solution I found to it.

The less popular answer is programmers like to pretend their software is going to be re-used the world over, when infact the majority of projects will be maintained by a small amount of people and however nice interface-related soundbites are, you're deluding yourself.

Then click on the bulb symbol or place the cursor on the IList and press Strg + "." You will become several implementations offered, like:

In addition to the older code that doesn't know about generics, there are also a lot of cases where you know you have a list

Convert your IList into List or some other generic collection and then you yaşama easily query/sort it using System.Linq namespace (it will supply bunch of extension methods)

+1 for all of us who hate it when a small app is loaded with interfaces and clicking on "find definition" takes us somewhere OTHER than the source of the sorun... Yaşama I borrow the phrase "Architecture Astronauts"? I yaşama see it will come in handy.

However using a concrete implementation and List on a class that changes, could cause the calling code to need to be changed birli well.

This will help if you decide to change the implementation of your class later to use a different concrete class. In that case the users of your library won't need to update their code since the interface doesn't change.

additional advantage is that your code is safe from any changes to concrete class as you are subscribing to only few of the methods of concrete class and those are the ones that are going to be there as long kakım the concrete class inherits from the interface you are using.
