Just a question, what if same user logged in two different devices? For example, a user logs in first device; it will update the RefreshToken column for that user in AspNetUsers table. On device 2 login, it will update the existing RefreshToken column value(it will replace the device 1 refresh token with device 2 refresh token) .So for device 1, how will refresh token work?

What if I use no secret?

Gracias saludos desde Chile

This is a gem❤

Thanks for the video

Very nice video !! I would love to see more. Just for clarification, it is quite difficult to follow from where "ReportThread" is called while looking at the output. Could you add maybe do something like: void ReportCall([CallerMemberName]string methodName = null, [CallerLineNumber]int lineNumber = -1) { Console.WriteLine($"Thread ID: {Thread.Id} at {methodName} line {lineNumber}"); } That would make is easier (at least for me) to follow.

Really great video thank you!

These tutorials deserve 10 times more views than they currently have. Always clear and concise with no waffle. Many thanks, Jasper!

I have a question. When I have a MAUI app as the client, for example, what is the best practice for the refresh flow to maintain a high user experience? Because when the access token is invalid, it would take six calls until I have the data if the token needs to be refreshed. So, should the token be refreshed in the background if it’s expired to maintain a high UX? Regards

1. They have to introduce vector math on arrays. Overloading operators +,*,-,/ create temporary objects. These in turn for long expressions and large vectors occupy as much extra memory as the number of extra temporaries. Fortran has it since decades ago, Zig has introduced it by scratch; it is unreasonable in 2024 C# not introducing vector math operations on arrays. 2. They should introduce a type for automatic differentiation (AD) build in the language so that 1st and 2nd order derivatives can be computed on the fly. 3. They have to introduce a feature for compile time code execution similar to Zig.

Great Video!

I have a question, but the topic is a bit different from Blazor. Basically, the question is about TypedReference in .NET (when we can/should use it) and about "hidden features" in c#, specifically __arglist and __makeref (again, when we can/should use them). I've done a some research, and you don't seem to have videos on these topics (

How can we return a Span from a function? Or any value type that has more than one field in it? In my understanding, when we return from a function, we pop the activation record, then pop the return address and follow it back to the caller. Since this pops the span from the stack, how do we use it in the calling function? With heap allocation, we can store a pointer in a register and use that to refer to the memory. Yet if we store a stack pointer to now unallocated memory, that wouldn't be good. So I'm really confused on how this would be used if returned from a function.

Finally i found a video where i learned the whole concept!

Wow! More than a year on since C#11 and I did not know about this feature. Really well explained thank you!

Such a great video

Best explanation yet on this topic I've seen

Hi Jasper, thanks again for your high quality videos! What happens when the user refresh the page in the summary page? Will the user still fetch the summary knowing that the JWt is still valid?

Hi Jasper, again thanks for a high quality content video!! I wonder, having the Clockskew within the gap of the Tiemespan defined in the validation parameters. Wouldn’t it be appropriate to make the refresh token endpoint protected with Authorize attribute and documenting that the refresh token endpoint must be called within X seconds/minutes of time span in order to generate a new JWT? So, instead of creating a logic for adding a column or attribute for Refresh Token in Users table, the clockskew is the key for refreshing a new JWT, thus the Authorize data annotation will do the work to validate the token. Thanks again for your videos, they are very helpful 💯

'System.IdentityModel.Tokens.Jwt' is a legacy tool :( are you going to update WebApi+Blazor wasm Auth tutorials?

Very glad I watched this video. I didn't know about the first method presented for using render fragments. Great stuff.

best explanation ....

Extremely useful feature. Thanks for bringing it to light

lul c# is really funny when one comes from c++ background... I was so lost.

Very useful and informative. Thank you.

very very useful tutorial. tnx a lot😊

Great video. It's quite a big change again, but I do feel that having such granular control will be worth it in the end. I'm still trying to figure out if how much traditional web api's lose their relevance in all this.

your content is addictively good! thank you so much.

one more amazing class, explaining deep things with simplicity.

I like to think of passing by reference as passing by value. Instead of passing a copy of a normal value type, we pass a copy of a memory address on the heap.

Awesome video as usuall, Jasper. I always look forward to when you release new videos.

Very helpful. Thank you so much.

huge help. i'll be implementing something like this. thank you

Can you make a video about Covariance and Contravariance in generics or about nullable reference types in modern c#? Also thanks for videos!

Very informative with great examples. I never come across this before and I've used RenderFragments combined and seperat mode for years. Thank you for sharing.

Hi! Thanks for viseo. can you please make a tutorial of aspNet web api + Blazor webassembly standalone app (not a `BlazorApp` or `Blazor Server` templates) Identity auth tutotial (new way, .net 8)? register, login, logout features and simple CRUD

Nice tutorial thanks!

Any other aspects of Blazor you'd like me to make a video on? Leave a comment. Source code available at: github.com/JasperKent/Blazor-Render-Fragments Remember to subscribe at ua-cam.com/channels/qWQzlUDdllnLmtgfSgYTCA.html And if you liked the video, click the 👍.

Please, can you update your minimal api tutorials to `source generators`? I've seen some articles about it but they explain so hard :(

Thanks for the videos, very good explanation and examples. One thing got my attention, the Christianity and Jewish books... Are you Christian?

Thank you! Didn’t knew about TypedResults and didn’t bothered much but just returned 200 if it’s fine or something else if we have troubles.

Thank you for this nice tutorial sir! Can you please tell me if we should return anything when we work with Minimal Api? I saw that people are returning Tasks and I am doing the same if we speak about Create, Delete and Update operations.

Is this the right way to do this?

Dear Sir, can you make a video about JWT and using Vue.js?

Only just discovered your channel, but so glad I did. Superb teaching skills. Already subscribed. Thanks!

your videos are amazing, yet another time only after watching your video I truly get an understanding of how sth works

This is such a good use case for this feature. I believe the official documentation also uses an HTML markup string. A while ago I thought of using the raw string in Blazor to store an svg. I don't remember the reason anymore, it was probably a number of icons and I just wanted to make the HTML more readable. So I copy the whole svg markup in a raw string literal aaaand... the verbatim identifier doesn't work in Blazor (yet). You can manually escape every single quote and slash or stitch together some abomination in a custom method or using the library's markup / html methods. There is light at the end of the tunnel. Somewhere around Visual Studio 17.11 Roslyn's lexer should be leveraged in Razor which would resolve this issue.

eng\Jasper... I want to ask a question? I heard someone say that asynchronous programming does not create multiple threads, and that it only uses one thread. I see here that a new thread other than the main thread has been created, and I trust you to answer this question. My sincere regards to you.😊

how can i update the password or remove the account (registration)? please make a tutorial about it
