Great video, thank you! Best tutorial. Too bad I dealt with Blazor and EF before then. But I gained knowledge regarding the structuring of the application
itwas a good tutorial, the best thing the fact that I did many mistakes I was able to understand more and try to solve those stupid mistakes by my self with reading code, really thanks I'm gonna move to the next one then build my first .net app Thanks a lot really !!!!
Your Blazor E-Commerce video series course is very good. Thank you for that. Can you also show Database First approach. I have found that most companies already have databases in place, and I would like to see a Database First approach(instead of a Code First approach). Would like to see Scaffolding of an existing database.
Great suggestion! Thanks a lot for your feedback and for enrolling! You're so right about existing databases in organizations. Problem is, in my experience, these database lack proper foreign keys, a good design in general, and so on. This does make a db first approach harder. Still, let me think this through. 😊
@@PatrickGod Would love to see database-first approach used also. In my particular case the relation between multiple tables and/or getting data from one table that references other tables (without really knowing what the content is of those). Current project I'm working only allows me to access one table in a db (no logical reasoning behind that demand, but need to roll with it).
Okay so the answer for your question at 38:11 is that on your controller for the GET endpoint you didn't specify a route, therefore, it is understood as "/". The route is /api/superhero since it's in the SupoerHero Controller. If you would have specified [Route("superheroes")] you would have had to do a call to /api/superhero/superheroes. I do not have a clue why how you got a 200 for the call though :)
Isn't it because in the controller, in the GetSuperHeroes method, there's only "return OK(Heroes)"? I'm fairly new to this but it is my interpretation of why the 200 is shown.
If someone faces this error "A connection was successfully established with the server, but then an error occurred during the login process. (provider: SSL Provider, error: 0 - La cadena de certificación fue emitida por una entidad en la que no se confía.)" you can solve it just by adding "Encrypt=False" in your ConnectionSting.
Thank you Sir Patrick for this valuable, useful and very practical tutorial. Sir, may I request on how to implement the CRUD using sql server? Thanks in advance.
Hey Patrick! Great Video. It is teaching me so much. Quick question. In my SuperheroRazorpages file. My monster service is not lighting up the same color as yours in the for each loop and i can not show my data to the table. It appears to be injected correctly. Any Clue whats up?
Loved this video, and am also making my way through the E-Commerce course! I appreciate you showing us how to debug errors that came up along the way. For future videos, could you potentially show how to write unit and integration tests against Blazor, where possible? I've done a little bit on against WebAPIs and databases, but I'd love to see even a short video on how that works. Thanks so much!!
Thanks for this video really cool. I have not clear at all the logic route of api components(controller, interfase and service) can you make a little video explaining that working schema?
Hey Patrick, big fan, I'm always laughing at your funny comments and edits. I have an eye on that blazor* game course you have, it seems like a fun way to learn deeper functionality. I just have to finish my current Udemy course first. Keep up the good work, best regards.
Hi, At first thanks for making such kind of good content. Actually i have a doubt in css isolation, how to isolate external css and how to apply css to a particular blazor component without affecting the other components, I will be very happy if you reply with some information and if possible try to make a video also for better understanding.
Hi Patrick, big fan of your way of making the videos and explaining all the details....can you please make a video on CRUD operation in blazor server app in .net 6
@@PatrickGod actually I tried making a basic CRUD application, but faces issues during migration and database update, errors in the datamodel for null/not null values, and combination of startup.cs and program.cs
needing the controller and two services for the functions...isn't that a bit overengineered by microsoft ? and won't it be much easier just to use a one to many relation in the dbcontext ?
@@PatrickGod Is it any tutorial about Audit Trail (logger that save user activity/event and their IP address to database like login, logout, create/edit something)? if not, Please make one Patrick
I tried to follow this amazing tutorial on .NET 7 everything ok until I added the Entity Framework and DBContext, and suddenly My Blazor app stucks in Loading and nothing happens, Whata can I do? Regards
One thing to add is if you opted to do Dbase first and created a table on your own, make sure you add Table and Column annotiations in your Models or you will get 500 server errors.
Excellent job! Thanks a lot for the video! I think the reason non-existing or existing services return 200 with error is that the view is responding (not the API) How do I remove the /api path from the view? For them not to respond as not found and for the api to respond to the /api path request
Dude, you are amazing! just a quick question: you are going always from SuperHeroService to Server Solution, but how we can solve a communication from server solution to superheroservice or UI? I mean, How I can solve the communication if there is a UDP Listener or a SQL Watchdog in the server solution that is causing an event that some value must be shown into the user interface?
@@PatrickGod thanks a lot for your response... I coded with SignalR but I cannot imagine how to merge this two systems.... if you make a video of course I will check it. Thanks again!

Thank you Patrick! This is a great tutorial, but I have one issue that I can't solve for several days now :( When I POST to my WebAPI to create a new hero using PostAsJsonAsync it sends null values to the controller. I managed to find an error that is thrown: System.Text.Json.JsonException: 'M' is an invalid start of a value. Path: $ | LineNumber: 0 | BytePositionInLine: 0. I can't find a solution though :( Anyone having the same issue?
hello, im following this tutorial but its giving me does not contain a definition for FirstName and no accessible extension method FirstName accepting a first argument of type .... could be found, are you missing a using directive or an assembly reference?
Although very interesting, I missed the usage of DTO's (Data Transfer Objects). Is there a reason that you did not include that aspect? In my opinion you should never have your models used by the client. The client should use only the DTO (e.g. the SuperHeroDto). Did I miss something?
Hi Patrick .. Your videos and courses are very useful .. Thanks a lot .. Just one comment .. I guess there is a duplication in code returning the list of heroes in ( GetSuperHeroes ) & ( GetDbHeroes ), you can only ( return Ok(await GetDbHeroes()); ) in ( GetSuperHeroes ) .. Best Regards ..
not to be critical or anything but putting all layers of your backend (BLL and DAL) in your controller is absolutely crazy. Why would you create a course with such an inaccurate example? It wouldn't be much more work to appropriately show how the layers are supposed to be used and why.. This is just pure laziness and would never be accepted professionally. If nothing else you should have broken the course up into segments so you could show how the professional world develops. There is no example of error checking or validity either in the API or in Blazor. This is like the difference in learning from a book and what is actually used in the real world. You gave the short, lazy book example. It would literally take less than 10 lines of code (per CRUD method) to show how it is supposed to be in a professional setting... especially since you are using code 1st. Kudos for using Fluent API over Linq for EF queries. However, if I ever saw a query like that in a controller - I would fire the developer immediately as they are doing nothing but adding spaghetti code to the project and will only cause pain and misery down the road when trying to maintain or expand the project (good thing for you there isn't much in the way of logic calculations - aka BLL). In the professional world optimized and correct are the only two acceptable examples of good code.
Sorry. But I would like to see a better and more understandable course on web api and blazor. Corresponding to all modern trends. If you have such a source, can you provide it?
@@maximf6670 Literally any other example on the planet that uses layers in .NET. (not that I am qualified or anything but..) I would say your example is a code example that was implemented in .NET extremely poorly - meaning it is not a real world example of how to implement the code. Trends? Who cares about trends? Professional programmers could care less about trends. You need to implement patterns and best practices. That would move your example a long way. I mean you are suggesting that out of the literally hundred thousand examples of Blazor out there your example is the best? Did you really honestly say you can't find better? Wow the arrogance level involved there... Nevermind I take it all beck.. You have the best example on the planet. No need to reply. Have a nice life...
@@maximf6670 Again.. You are completely missing what I said in my original post. You are not providing a course you are providing coding samples. If that is what you call a professional course when you shove everything into the controller - not a single layer in any of your examples. It is a layer vacuum in there... wow bro. WOW. Layering is like basic intro to .Net 101. But you do you... Oh, and I don't work for you. I offered criticism and it didn't work but I'm not going to do your research for you. I literally told you all you had to do was google. You will find an abundant amount of courses on Blazer using the latest patterns and best practices. They are all over the place. I'm beginning to see how you lazily code. Good luck with the course. Cheers.
And now please without EF! For real, this component is sort of for idiots. Honestly, I've attempted to implement a thing or 2 that is doesn't match millions of books, tutorials here, and started getting most idiotic error from EF. EF has no future in serious enterprise!
