What language would you like it in? If it isn't in C# it could be in Java script.

I apologize Ji Ch, this tutorial is outdated and have not had the time to update it. I should probably take it down.

I will check it out for you when I get some time. Thanks

It shouldn't have anything to do with your .net core version. What error are you having?

@@keithwilson4284 Gee Keith thanks for the reply. The issue/problem: No send or receive of a message. (Don't know if a message is being sent.) Click 'Send Message' button and nothing happens with 2 browser instances open. Application state: The app opens in browsers and looks exactly like yours. Note: I have years of experience in VB and C# and WPF in VStudio. App goal: Trying to send data from user phones to WPF app. So I'm real interested in your SignalR WPF video. That's next after I get this working.

Hope that helps. I would convert it for you, but I have a deadline approaching soon and this client is not going to allow me to miss it. :)

More info: In the VS Output window getting these 2 errors: Could not read source map for localhost:44358/js/signalr/dist/browser/signalr.js: Unexpected 404 response from 1. localhost:44358/js/signalr/dist/browser/signalr.js.map 2. Uncaught SyntaxError: Cannot use import statement outside a moduleThe thread 0x1920 has exited with code 0 (0x0). As mentioned above, this line is inserted automatically by VS in chat.js: import { signalR } from "./signalr/dist/browser/signalr"; ... when I type the line: var connection = new signalR.HubConnectionBuilder().withURL("/chatHub").build(); In your code signalR, in the line immediately above is colored blue. In my code it is not. To me this could mean I should be referencing a class signalR somewhere. Instead the code is doing an 'import {signalR } from ....' .

If you need any help with anything at all I am open to any communication you like and all absolutely free of charge. I appreciate your support.

You are welcome, I hope to add more soon.

You can use both, I used it in the tutorial only as a use case, .net core is just as easy to set up, and I plan to release another video using all .net core. For wpf apps, the use of .net core is limited due to wpf not running on any other platform except with xamarin at the time. I am here to help any way I can.

Thank you Ankit Nagpal, it is people like you who will get me to share more of my knowledge. I appreciate the sentiment.

@@keithwilson4284 My project has requirement to send real-time information from ASP.NET server to WPF Windows software and a Xamarin mobile app. I was exploring WCF and long polling, I guess SignalR is the way to go in my case?

@@i_fuk_religion Absolutely, signalr sounds defiantly like what you need. Even though WCF was a great technology, however we only really use it now to connect applications on the same network, I have seen signalr used with WCF and understand they are different technologies. For internet and cloud solutions, we use REST and Signalr. Other technologies equivalent to Signalr is Firebase, Pusher, RabbitMQ, WebRTC, MQTT and SOCKET.IO.

It is best to keep your payload small, basically I will usually send a key via the response and just have the client then fetch the changes. So I communicate in each crud operation in the api to notify all connected clients of any changes. I will work on a tutorial to better explain it.

​@@keithwilson4284 Thanks Keith hope that i will be notified for the further updates on this.

The asp.net uses .net core, .net signalr and .net core signalr are not compatible. You are better off going with .net core for both server and client, however in this tutorial I wanted to show that it is possible to use .net core libraries in a standard .net application.

If you need any additional help on set up, just shoot me an email [email protected]. I am currently working on a large project that seems to keep getting larger, but I will help out the best I can. I plan to do more tutorials in the near future as soon as I finish with this client.

You can use .net core, but at the time of this recording I was still developing in .net framework.

Glad to be of help, I do plan on posting more in the near future, just been busy on a contract, however if you do need anything specific, be sure to let me know and I will try to help as best I can. Thank you!

Yes I actually did. LOL. However if you didn't I would be more than happy to help you with anything you like. I actually made that tutorial quite awhile ago. Just let me know.

@@keithwilson4284 i require help Please let me know how to contact you

Email me at [email protected] and I will help you with whatever you need.

Imagine being toxic to person who wants to help you

Daniel I will check that out for you. If you need help working it out, I will be more than happy. Thanks for the reply.

Daniel email me at [email protected] so we can figure this out, I am not seeing the same you are apparently

You are most welcome

Flow Wolf, thanks a million for that. I really appreciate your contribution. I am on contract currently, but if I can help in any way, just shoot me an email or continue on here.

What other parts are you referring too, I would like to help if I can.

@@keithwilson4284i thought it was just the intro into the whole signalR setup you did! :D

No, I have not tried it.

@@keithwilson4284 Cool thanks for the quick reply :-)

Thank you for your feedback, I appreciate it, and fixing those issues in upcoming videos.

1) you can await startasync() I just didn't in this tutorial. 2) the while true is just looped until you break out of it. I do not recommend in production however due to an infinite loop. I again only used in tutorial. I will try to do more real world examples when I complete this contract I am on. Should be back publishing more content in June.

Thank you for your input. It is greatly appreciated.

No Problem Maaz Syed, I will be more than happy to make one up for you. I love Angular. Thank you so much for your support. I will get better the more I practice these videos.

Maaz buddy, I am sorry not doing an Angular video as promised, I got into a contract and made things a little difficult. I however will be returning around June to upload more content.

@@keithwilson4284 Hey Keith, All good. I figured out a way to do it myself, nonetheless when you get a chance, will surely check that out as well. Thanks

I do agree with you, and appreciate the feedback. I always strive to do better, and that really helps. As far as you doing a live stream, just go for it.

@@keithwilson4284 Between the two of us, we will catch Joe Rogan on subscribers in only 35,000 years if he stops now.

@@DataJuggler isn't that the truth, guys a beast.

Thank you Roman Kolychev, you can download postman from getpostman.com. I use the desktop version, however they do have an online version also. I use postman for all my api development, it allows you to send requests to your api's without creating a client side application or writing a lot of test code. If you have any more questions, feel free to shoot them my way, or let me know what you would like to see in a tutorial. I have been meaning to record more tutorials, and hopefully I will get better. I have seen where I have made a lot of mistakes. I too am always learning new things. Thanks again!

@@keithwilson4284 Thank you for reply. I i want kind of framework to comunicate between server app and client apps and thought SignalR should help me.

@@DeMoZyou signalr will do just that. You need any help just let me know.

@@keithwilson4284 if you make the video about sending messages between server and client aps using SignalR , that would be awesome!

Thanks buddy, I will be posting more soon.

Thank you.

Thanks Keith, I appreciate that so freaking much and I will work on those things I promise.
