Rate Limiter in Asp.Net Core | Web Api | C#
Rate limiting is a technique used to limit the number of requests a client can make to an API within a specified time period
It can be implemented to,
Prevent Denial of Service (DoS) attacks
Generate revenue (users can subscribe to get premium/unlimited access to the resources)
Maintain system stability and prevents one client from overwhelming the API server with an excessive number of requests
Rate Limiter algorithms are,
Fixed Window
Sliding Window
Token Bucket
Concurrency

How to access appsettings.json file in controller
Why use SqlTableDependency? If I don't use SqlTableDependency and use NotificationService to notify when the user wants in Controller, is that ok? For example, when I comment on someone's post, in CommentController I will use _notificationService.SendNotificationToClient(message, userId)
Excellent video. Very very helpful. am not getting the dialog box, ony return value from the RazorPay(options), what am i doing wrong ?
why dont use UserId in aspnet entity to make a connectionId. I think dont create a table HubConnection ???? Please explain for me
hey @canduykhanhk16_hl93, to make the video simple (to avoid join User and HubConnection table) I just used Username in HubConnection table. But in real time, we would use UserId.

Hi every time i am running an sqltabledependency and signalr project i get this error: System.DllNotFoundException: 'Unable to load DLL 'sni.dll' or one of its dependencies: The specified module could not be found
This is so super helpful and easy to follow thank you, how do we save these messages to the database?
Hey, thanks for your words. And, you can easily save the messages by calling repository in the required Hub Methods in ChatHub class. If you need more help, please let me know.
One of the best videos I have used. Thank you!
Thank you very much!
Thank you! You helped me on developing my cube solver app. I had to create a loading popup for connecting to the robot by Bluetooth. Thanks again!

Thank you so much for your kind words. Thanks alot.
Unfortunately, Sql Table Dependency has not been updated since 2020, so it can hardly be used now
Much appreciated. Can you also show to i save XML files in order to be read and rendered later by another method?
This is gold

Hi when I update something in the table, data is not getting reflected
Probably you're missing something. Could you share the code with skynetechs@gmail.com, we will check and come back to you.
This is super cool and finally got me interested in DI. Appreciated.
Thanks for your words!!
Al probar la conexión de mi proyecto no funciona.. Sera porque uso puerto no seguro? En su caso al momento de ejecutar su proyecto usa certificado valido! Como hizo eso?
Antes que nada, gracias por escribir. Lo siento, no pude entender la pregunta correctamente. La conexión no funciona, ¿significa que no puede conectarse a la base de datos? Si tienes más consultas puedes escribir a skynetechs@gmail.com
while creating the project i chose empty project so there is not sitemaster what should i do?
Probably, you can add it through Add New Item menu context.
Thank you so much. A big question mark about my project has been eliminated. Perfect solution!...

Hello there, thanks for the comment. I definitely try to help you on your issue. Could you please share the code with skynetechs@gmail.com so that I can take a look and please clearly explain the problem, it helps me to get it quickly.
When I run the code for maui it doesn't work the error is: System.Net.Http.HttpRequestException: 'No connection could be made because the target machine actively refused it. (localhost:Localhostnumber)'
This could be an error because your api application may not be running. Please check once.

Hello, I've already shared the code base in the description below. Please check.
This is awesome. Thanks for sharing..
Thank you very much!!
can you make this with code first approach

Dude, you're saving me an uncountable amount of time with this fantastic demo. I mean it -- I have no idea how long it would take me to learn this stuff; and it's not just the data management, it's little things... like how Flyout menus work. Or logging. Just know that some random person out there in the universe owes you.
I really glad to read this comment and I'm equally happy that my demo is helpful to you and others. Your words give me boost to make more such videos. Thank you!
First of all, thank you very much for the video. Thanks to you, I applied SignalR and SqlDependency in my project. Everything was working properly but then I changed my query method on the Hub side. The change I made on the table side was to use a relationship. Then it gave an error. This is the error in the console, Error: Connection disconnected with error 'Error: Server returned an error on close: Connection closed with an error.'. and Error: Server returned an error on close: Connection closed with an error. function InvokeTaskList() { connection.invoke("SendTaskList").catch(function (error) { console.log(error); return console.error(error.toString()); }) } This is where he catches the error.
I apologize for the delay, could you please share the code with me at skynetechs@gmail.com? It helps me to dig into the code and see what's happening inside.

Brother I have an issue, so when I public my project on server it gives an error : failed to connect to the websocket/ Negotiations something like this
failed to complete negotiation with the server: error: : status code '404' either this is not a signalr endpoint or there is a proxy blocking the connection. failed to start the connection: error: websocket failed to connect. the connection could not be found on the server, either the endpoint may not be a signalr endpoint, the connection id is not present on the server, or there is a proxy blocking websockets. if you have multiple servers check that sticky sessions are enabled.
Your issue would be blocking the connection. Please check that your requests are allowed in the server. Your server might blocking the requests.
Excellent
