Your content's trustworthiness has become my go-to, when looking for C#/.Net subjects.

[ibrahimhussain]

Yes. I would very much like to see the winforms and WPF version of this.

[TheJessejunior]

uowwww!!! great content as always, tim!!
my skills have grown so much since i´ve started following your videos, I usualy watch them several times and they´re my first consulting material whenever I get doubts during daily job....

[divanvanzyl]

Bro your videos are AMAZING. You are covering the topics that we want to learn about, but other people are not covering!

[JonathanPeel]

I especially enjoyed this video.
I enjoy most of these videos, but I especially enjoyed this one.

It is greater to watch this, even if you never intend to write a console app, and explains the DI that gets used when writing an ASP/Web app.

I really like how you will always say "Don't do this in production" and then go back and fix it.
It can get a little frustrating when going through tutorials that say things like that, but never show you how to actually do it 'properly'.

I’m happy to see this. I’m a developer who primarily works on windows worker services / windows services, and a lot of backend applications where there is no user interaction. A lot of people forget that there are a whole realm of developers who aren’t primarily working on web.

[josepiratilla]

First of all excellent videos!. I wanted to add that at 38:00 another very good reason to pass parameters separately is to avoid the string manipulation if our log level is higher.

Tim, this is pure gold:
var svc =
Save my life on a few console application that I'm now refactoring to hookup DI properly or the right way. Thanks a bunch.

[AmitDileepKulkarni]

Thanks Tim for teaching us dependency injection in a very simple way !

[RobertOspara]

Great tutorial :-) Tim treats wachers as human beings: inteligent and smart, because he is very inteligent and smart and tries to predict eventual question or request and imediatelly answer to it. What a great guy :-) But without self-exaltation.

When I see the "I" in the channel's name, I always think it's an interface.

[oncalldev]

As always a very clear, tight explanation of how things work in the .NET world. Thanks.

[jalvrus]

Thanks for the underscore tip; that will save me some time. I recently implemented something like this using AddHostedService to register the operation class (GreeterService in your case), and host.RunAsync to execute it. The trick with this approach is to call at the end of the operation to terminate the process.

[KhachaturStepanyan]

So well put, I almost never come across a video where you follow tutorial step by step and it works, usually something is missing, something is forgotten
thank you!

[BlahzayBeta]

The copy output directory tip was clutch! Exactly the issue I was having. Great video as always. Thanks

[mbrotto]

I love the refactoring option (underscore) update...I have been using that for a while now...just popped back as I had lost it...oh and the content is great too ;o) Thanks for the great content Tim.

[lockegarmin]

Good video. Just a couple clean up items that were forgotten:

1. *host* is an IDisposable, so you should wrap it in a using in your main method or call Dispose() manually. This way it cleans up every dependency that you might have living in your dependency injection.
2. It's best practice to call Serilog's Log.CloseAndFlush() method at the end of your program since you created the logger outside of the hosting environment. If you configure Serilog in the .UseSerilog() method, you don't have to do this (assuming you are disposing host properly).

[oscarjr]

Thank you so much for this!! I discovered this video after struggling with migrating some code from the Framework to Core. The video demonstrated the functionality in a way that I could easily internalize and use. Subscribing to the Patreon is the least I can do. Be well!!!

[marcouitendaal]

spent most of yesterday figuring out how to use configuration in a console app, including the build option of the appsettings file to 'copy if newer'
then i was wondering, how could I make dependency injection work in a class that's being instantiated through the console.
I figured that it must be some kind of host that hovers over everything, cuz how could .Net do it otherwise, but how to have it active in a console?
And this morning this precise video showed up. An hour well spent.
I've been messing with .Net courses on Udemy, but yours is next on the list!

25:54 I totally agree! It was so pointless to look at Microsoft documentations a few years back. Now they even have little walkthrough tutorials, although for me to read the documentations can sometimes be a bit overwhelming. So tutorial videos like yours are still very precious. 😅
