Can you please explain :Why cant we we get the instance of ServiceCollection, then a ServiceProvider and use the "GetService" method on it to get the instance of the GreetingService.
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.
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.
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 IHostApplicationLifetime.StopApplication at the end of the operation to terminate the process.
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.

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!
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).
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.
I actually figured this out on my own when playing one day. However, there are tons of other things I learned in this video that I wasn't aware of. Subscribed!
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. 😅
This was a REALLY cool thing to watch... just like 2 weeks ago i was trying to add Dependency Inyection to my console app but i was looking forward to use native microsoft stuff.. Thanks for this!
When you talked about how reading the error message helps, I remembered some really bad moments I have had with a certain C++ compiler xD I think the C# compiler generally does a good job though, as you say, so that's a relief. Thank you for the video, it's great as usual :)
Thanks, Tim. This video helped me a lot. I liked the underscore tip. I've been wanting to figure that out for a while. And using Serilog looks very promising.
It would be awesome if you could do a video on how we would best create Unit Tests for such a project and test the services that are expecting the ILogger and IConfiguration to be dependency injectected.
Tim has done multiple videos on Testing, but I will add the suggestion to his list. Explore these to see if they address what you need - ua-cam.com/users/IAmTimCoreysearch?query=test
Great video, as always. Just a small nitpick. I wouldn't recommend choosing "Copy always" as a copy option for a file. This forces the project to rebuild every time you build or start the application. This is especially annoying in libraries as they and their dependencies will always be rebuild instead of only when the content of any file changes. "Copy if newer" will almost always suffice except in special cases with dynamically generated files.
Very well laid out Tim. Thank you so much and you are right, Serilog is a good tool and with your code right here, anyone can be up and running in a few minutes.
Hi Tim I really appreciate you doing ML.NET in C#. There are very few tutorials out there, and they are not explaining things well as you. Hope you do ML.NET series :)
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!
Great Video Tim, One question, when the service creates the instance of GreetingService How does it know what values to set the constructor parameter objects to? Can you specify them?
Please do! IAmTimCorey.com and UA-cam channel ua-cam.com/channels/-ptWR16ITQyYOglXyQmpzw.html Purchases directly fund my ability to provide the free content. Thank you for being a big part of making these free videos available.
I read other peoples' code mainly. I see how other people approach a problem and then I take the best parts of what they do and I mix those with the best parts of other projects I have seen. The more code I read, the more perspective I get on useful libraries. This sounds like a great Dev Questions topic. I'll add it to the list.
Serilog is all we use where I work. I remember when I first started working professionally, I had to learn how to write a "REAL" console app, because the insurance industry is loaded with EOD console apps. All I was used to was beginner tutorials, and they are used much different in the real world.
I would love to see a continuation of gRPC that goes more in depth, i cant really seem to find any good advanced guides for c# on gRPC including things like Authentication, Authorization, Security, sending caller information metadata, logging etc etc. That would be great! Thanks for all the great stuff you put out, i was just working in my brand spanking new gRPC console app and thought, hmm how do i get dependecy injection working and i found this :)
I'm liking the videos, very informative! My only gripe is that you elaborate a bit too much on simpler topics when the subject suggests a more advanced user. E.g. in this particular video you're looking at more complex things such as DI, but you're also guiding viewers through how to add packages and using statements, and basic Visual Studio usage which I don't think is necessary for more advanced topics and drags out the video length unnecessarily. If you haven't done one already, I recommend making a separate video specific to these basic setup/IDE-specific features, which you could then simply reference as and when required.
Thanks for the feedback. Tim believes in giving context for what he is teaching and that takes time. His goal is not entertainment or just to dump knowledge on you but true education. Its a constant balancing act and your feedback helps.
Hello Tim ! Thanks for another helpful and great video. At 52:24 you chose CreateInstance but wouldn't it be better to use GetServiceOrCreateInstance that accepts the interface as well ? It makes more sense as the advantage of DI is to predetermine what concrete class to use in the services configuration at line 31 making it easy to choose another concrete class right ?
It looks like the builder object is similar to what CreateDefaultBuilder is doing. You're only using it for Serilog. Couldn't you grab the IConfiguration from the service provider in host and omit the builder object?
Good question and I wasn't as clear here as I should have been. We need to grab the config file before the Host is set up so that we can log any errors that occur when setting up the host. That's why we manually set it up instead of waiting for the host and getting it then.
Hey Tim, on an unrelated note, have you considered offering your courses on a subscription model? I think many many people would sign up in a heartbeat. Although your current model may already be working fine!
I do offer a subscription model. The All Access Pass gives people access to all of the public courses on IAmTimCorey.com for a monthly fee. I open access to sign up every couple of months. Registration will actually be opening soon, so make sure you are on the mailing list so you are alerted when it opens. It only stays open for a few days.
