It was a series that I never wanted to end, but of course we have come to the end of this, this will be my first project that I will publish, I have learned a lot, now I will try to add new things and play with what I have learned from you. My humble advice is to offer such works for members or to be on different platforms such as Udemy. I will buy you a coffee as soon as possible. thanks for everything.

i'v got error in LoginUserAsync: Error: System.NullReferenceException: Object reference not set to an instance of an object. at Microsoft.AspNetCore.Authentication.AuthenticationHttpContextExtensions.GetAuthenticationService(HttpContext context)

hi love from vietnam

So just a quick question, why didn't we use CRUD Operations and Scaffolding out the DbContext? If I do that for new models will it conflict with existing migrations and db info?

Dear Abhay Prince, I am a huge fan of yours! Thank you for always providing excellent content. Could you please provide an example of consistent state management in Auto Render Mode, regardless of the location of the Client and Server? I’m looking for a good way to synchronize and manage states when the Client and Server locations change, as the states tend to operate independently. Thank you so much, as always!

i love you

You're the best at MAUI!!

I also prefer this approach. It's a bit difficult to follow along when entering also the code, but it's great way to learn.

Dear Abhay Prince! Thank you so much for your work! The application crashes at the line "var response = await QuizApi.SaveQuizAsync(_quiz);". I can't understand why. Debugging does not give an answer. In the browser localhost:7264/api/quizes 401 Unauthorized In the Console tab there is an error Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100] Unhandled exception rendering component: Response status code does not indicate success: 401 (Unauthorized) Please tell me what to check. Thank you!

excellent thank you

Thanks

I followed your video and implemented the code line by line, however I keep getting this error while trying to render the return api call: Refit.ApiException: An error occured deserializing the response. ---> System.Text.Json.JsonException: The input does not contain any JSON tokens. Expected the input to start with a valid JSON token, when isFinalBlock is true. Path: $ | LineNumber: 0 | BytePositionInLine: 0. ---> System.Text.Json.JsonReaderException: The input does not contain any JSON tokens. Expected the input to start with a valid JSON token, when isFinalBlock is true. LineNumber: 0 | BytePositionInLine: 0. at System.Text.Json.ThrowHelper.ThrowJsonReaderException(Utf8JsonReader& json, ExceptionResource resource, Byte nextByte, ReadOnlySpan`1 bytes) at System.Text.Json.Utf8JsonReader.Read() I spent a lot of time debugging this, and I instead created a new page table format rather than the QuickGrid. Please let me know if you have any suggestions.

Any new course about .Net 9?

Great video ! Just of curiosity, why are you using array's and not lists?

it is much better to solve it at the same time, at least now I know where to look and how to find a solution at the moment of the line

ad usual great content and presentation

You best man .Thank you

sometimes you have to delete the .vs folder and reopen the solution

Good Sir

Special thanks from Egypt

Great job

You need to set some chapters in this. It's so long that going back to something we missed is quite difficult.

A one of its kind marathon tutorial, great stuff! 👍👍

Good stuff

Sorry, I forgot: if it can be useful to know that it crashes when I check the "Jason radio button" and click on the input area, the error is: "An unhandled error has occurred. Reload" Thanks a lot Ferdinando Geraci

I am a new subscriber, congratulations on your work, I ask you if it is possible to ask if the Visual Studio 2022 Enterprise version is compatible with the project described above? I can't go forward in the BodyTabContent.razor tab, at position 2:52. After inserting the instructions: @onfocusout="OnFocusOut" @onfocusin="OnFocusIn". Thank you very much Ferdinando Geraci

Curious why you didn't add the Blazor Web to this demo? How would I add a blazor web to this solution?

dedicate video for DevTunnels please

Excellent tutorial, watched this part in isolation from other videos, lot of helpful information for making a header in blazor!

who you display Quickwatch Expression Deialog in 30:07 ?

Good Sir Thanks

My app is not working on release Mode after published project. How can i solved thos

Thank you Abhay!

Amazing work is made in this video!!!

for me, HttpContext returns null. Do you know what can be the problem?

Can anyone do their homework? I couldn't do it :(

Since the videos appear on the screen at the end of the video, I cannot see the last changes you made. Thanks.

Hello, your education is very good, thank you very much in advance. It's progressing very well. Will you release the app on the Play Store or elsewhere in the future? We would be very happy if you implement the project. Thanks.

I’m interested in purchasing this project, but I’m facing an issue with a different project I purchased earlier. I’m unable to run it in Visual Studio 2022. Could you help me understand how to run the project if I decide to purchase this Build Fullstack Online Quiz Web + Mobile App with Blazor WASM + .Net MAUI Blazor Hybrid?

Great tutorial video but i'm stuck in AddMigration procress. I did all following your example but when I finally create the migration in the folder i have an error i cant'fix. public partial class InitialMigration : Migration (Migration is Red undescored giving me an error.) { } could you help me? I'll really appreciate it.

You are HUGE! Your content is EXCELLENT!

25/41 When I click the "Save & Next" button, I encounter the following error: Response status code does not indicate success: 404 (Not Found). How can I resolve this issue? Could you please help me?

updated VS 2022 and ran into the issue of Pending Migration Error, after adding this line it will suppress the error and initiate the migration, not sure of any of possible fixes at the moment Add-Migration will work fine, but it's when you go to run the application it will throw a pending migration error, if there is any other suggestions, please let me know. here is the solution I came accross builder.Services.AddDbContext<ContextNameHere>(options => { var connectionString = builder.Configuration.GetConnectionString("ConnectionStringHere"); options.UseSqlServer(connectionString) .ConfigureWarnings(warnings => warnings.Log(RelationalEventId.PendingModelChangesWarning)); }); github.com/dotnet/efcore/issues/34431#issuecomment-2427448776
