This is the best Singleton tutorial i've come across. Great stuff!

Nice tut, but I must say that it does not explain when and why I should use such pattern, I think it would nice to have something like that but more orientated to a real scenarios because this is too simple

Excellent demonstration

Helped a lot, thanks

Simple and precise

easy to follow. Best Tutorial ❤

Glad you think so!

Thank you!

explained very easy way 😊

sehr schön erklärt @ 08:42 .. lock gab es auch schon in delphi 5, eine sehr nützliche Funktion um gleichzeitige threads doch noch unter Kontrolle zu bringen *g

Nice! Great job 👏🏻👏🏻👏🏻

Thanks! 😊

Thanks ! Pls do videos on other design patterns as well

This is great tutorial. Can you please add more videos for other design patterns like strategy, observer, facade etc?

Superb

good one

What if we have a distributed environment , multiple instance of this service would be running, how do we prevent multiple instances then?

Nice tutorial

Thank you! Cheers!

Wouldn't it make more sense to remove the outer check for the null instance? I say that because you now have the same condition duplicated in your code which isn't ideal or efficient.

If the outer check is removed, the application will acquire a lock every time the instance is requested, impacting performance.

How about this approach? namespace SingletonConsole { public sealed class UploadService { private static UploadService _uploadService; private UploadService() { } static UploadService() { _uploadService = new UploadService(); } public static UploadService Instance() { return _uploadService; } } } Static constructors in C# are thread safe, so this will guarantee that _uploadService is initiated only the first time UploadService is referenced.

@8:40 is the critical section of this video thread.

Hi there very interesting tutorial. Unfortunately though I'm receiving two errors: 1. Program does not contain a static 'Main' method suitable for an entry point (CS5001) 2. When I try to pass values from my instance threads it says that UploadService is inaccessible due to the protect level of my class being sealed/private. I'm new to programming so I'm a bit lost at the moment as I had to create a new project/program to link it with the UploadService class. What should I do?

Hi, awesome that you try it out! Make sure that your program cotains a "static void Main" and that you create a "public class UploadService". Also set your program class itself to "public". Greets :)

Instead of manually managing a lifetime for a service, using static etc it should be done via DI container and in the real world nobody does it the way in the video.
