Thank you very much! :)

Thank you! 😊

You're welcome! 😊

Thank you so much for your kind words! Unfortunately, my audience is at the time very small, so i can't dedicate the time for a full course. Having said that, I'm preparing a project with concepts (among some of those I talk on my videos) like DDD, microservices, token auth (including refresh tokens) and others! Althought I can't go step by step on videos, I'll let you all know when I upload it on github (hopefully before autumn) and probably I'll make an overview video about it.

You're very welcome!

Hi! I suppose you could, but in what form are you going to store them?

@@spyroskatsios now i try to study Drools. but dont know how to install and integrate with eclipse (java). so i not sure c# also have rule engine that can keep rules in configuration file, xml or database or not?

Thanks! Glad you liked it!

You can still use it, but since it's a 'contract' for not returning anything, this update removes unnecessary code!

@@spyroskatsios OK cool thanks

Newer videos have bigger font size!

Thanks 😊

Thanks a lot man!!!

Thank you very much! 😊

Really appreciate it man!

If you are talking about manually invalidating it, didn't fit in the logic of that video!

@@spyroskatsios yeah that’s the one. Cool, looking forward to your next video :)

Thank you for your consistent kind words! 😊

Of course! github.com/spyroskatsios/UA-cam-SearchFilters

@@spyroskatsios you are a super star :)

I like your solution! Thanks for your kind words!

You are very welcome!

You are right! You want to have a mechanism of handling domain events fails. Wrap in a transaction the process of handling them, if you want the changes to be immediate, wrap in a transaction the process of saving them if you use the outbox pattern with eventual consistency, etc. I wanted to keep it simple and focus only in the publishing with Mediatr side of things!

Thank you!

You're welcome! :)

Thank you very much!

I uploaded it: github.com/spyroskatsios/UA-cam-RulesEngineDemo

thanks @@spyroskatsios

Thanks a lot!

If I don't hear that clicky sound, I don't feel like I'm coding 😂 Thank you!

Because we want to treat them as different entities in the app. The point is that we can have different ones, but still save them on the same table, if we choose to.

You mean without Discriminators? Like two entities that one has a list of the others?

@@spyroskatsios no with Discriminators the same like you how u created Hero that extends person . i want to make manager that extends Person and contains a list<Person> employees for example

@@mohamedal-qadeery6530 doesn't it work with the default way, by adding the List to the Manager?

@spyroskatsios No it didn't work or maybe i did something wrong idk

@@mohamedal-qadeery6530 Add the property to the Manager and also configure it with HasMany inside the ManagerConfiguration.

Thank you my friend!

Thank you very much! Can you give me an example of what needed more explanation?

Thank you very much!!! Yeah, i hope it'll grow a little at some point!

Maybe the video about blazor services lifetime will make it clear. If not, I will happily discuss it :)

What do you mean by "use"? How you register it? If that's the case, you can register it like in asp, given that you have set up dependency injection for your console application.

That's the point. That using asynchronous implementation with synchronous code is not ideal. That's why i used the EF example and i mentioned libraries, like the EF, that provide sync and async methods for the same operation. That's exactly what I said. That there is always going to be an overhead, but the benefits outweigh that in some cases because we delegate the task to a different thread, so the current one is free to do other work. About the third argument I don't know what does it have to do with this video. Yes, if you are inside a method that returns a task and the only async call is to calculate the returned result you can return that without waiting it. But that's not always the case and again someone needs at some point to await that and you still have some overhead. Overall i don't think that i communicated something different from what you wrote in your first two paragraphs.

That's interesting. Did you try to put breakpoints in the behaviors to see what's happening?

You're right. Maybe I should have used a transaction or an example that the events change the state of an entity, but not call the SaveAsync and publish them before i persist any changes, so the save call save them all together, but i wanted to focus on the publishing side of things!

@@spyroskatsios it’s an incredibly complex topic that is giving me no end of headaches. This is a really good video though that works perfectly well when you’re not being a linguistic purist!

Thank you!

You are welcome! Hope you did well in the interview!

What do you mean? If you set in your configurations how you want to handle your relations, it will not set them automatically. Maybe i didn't understand the question, can you give me more context?

@@spyroskatsios lets say i have a use case where i just need the person name and i dont need to include all the relations like credit cards,etc ... because by default based on the video everytime when u get the person it also includes the relation (all credit cards)

@@mohamedal-qadeery6530 Now i got it, thanks. Since they are owned entities you can't by default not include them. You can use a select and retrieve only the fields you need in this specific use case. If you have multiple read use cases like this in your project, but you still want those entities to be configured as owned, you can maybe have a different dbContext for the reads.

@@spyroskatsios can u make video or code sample in the future ? And thanks alot

@@mohamedal-qadeery6530You are welcome! About using a select clause to project to a custom object i don't think there is a lot to do. If you are talking about the second dbContext i have one: ua-cam.com/video/QkHfBNPvLms/v-deo.html

Thank you very much!

Thank you, i will!

You are welcome!

Thank you!

Hey Ebrahim! Unfortunately I don't have any experience in this area, I'm sorry.

@@spyroskatsios no worries my friend, I understand it is a not common to work with soap this days , but if you find your self integrating with banks and Telecom providers as I do 😅you will need to come up with different ways of doing it .
