SignalRChat

I am totally new in docker/azure DevOps build pipelines. But I have to admit, it is a painful road. This suppose to be easy and it is not:)

What I want to achieve is to only build one project which has one referenced project in the solution. But I don't want to build the whole solution (as I have Xamarin projects which takes a little bit longer to build) As for SLN - I suppose the answer would be easier to find.

I did have this pipeline working when there was only one project without other projects being referenced. But right now, as I referenced one, it breaks.

Just for the records, I am using a build pipeline to create a docker image and deploy it to Azure Container Registry. But that is not important I suppose, because it is failing on building.

My Code structure

• Solution

  • [Project] BuildChat <-- Referenced project by SignalR
  • [Project] Xamarin.IOS
  • [Project] Xamarin.Android
  • [Project] SignalRChat
    • [File] Docker

My initial file was created through Docker Support addon on VS (proposed here: asp.net core 2.0 - multiple projects solution docker file)

Of course, when I first used it it didn't have referenced projects. So I thought, ok, maybe I will just remove docker file and use Add-->Docker support once again. And it did change the dockerfile to include the referenced project (called BuildChat)

So after the changes my docker file looks following:

There is a confusion in the arrangement of codes and the place where it pleases so I hope to find an explanation for the following:

When I have a server "https://localhost:48009/" and the application is equipped with all the requirements of Signal-R and also Hub exists on it. in folder Hubs There is a Hub Class ChatHub.cs

I'm making a chat application in web api ASP-NET with C# in VS Code. The user registration and login is working with database. I added the SignalR sample code in to the Welcome page, but i want to modify: the User name need to be the logged username, and after when i click to ''Send Message'', need to look like this: ''acc1 says hello world''.

SCREENSHOT ABOUT MY PAGE

The ''Send Message'' button function is in the ''chat.js'' file, and i don't know, how can i get the ''username" string there. The HttpContext.Session.GetString("username") is not working in javascript.

I am trying to add security/authentication to my SignalR hubs, but no matter what I try the client requests keep getting a 403 - Forbidden responses (despite the requests successfully authenticating).

My project is based on Microsoft's SignalRChat example from:

https://docs.microsoft.com/en-us/aspnet/core/tutorials/signalr?view=aspnetcore-3.1&tabs=visual-studio

Basically I have an ASP.Net Core web application with Razor Pages. The project is targeting .Net Core 3.1.

The client library being used is v3.1.0 of Microsoft's JavaScript client library.

I also referenced their authentication and authorization document for the security side:

https://docs.microsoft.com/en-us/aspnet/core/signalr/authn-and-authz?view=aspnetcore-3.1

The key difference is rather than using the JWT Bearer middleware, I made my own custom token authentication handler.

I have a functioning SignalR hub that I added Groups to in order to better control messaging, seemed very simple except that no messages are received by anyone in the group. I'm using SignalR for asp.net (not Core) v2.4.1 (latest stable release). My hub code is:

I have a simple project where I want to implement SQL dependency. my problem is that when I insert a row in a database, only once the changed event handler of SQL dependency gets triggered and not anymore.

in startup.cs I have put this:

Using .netCore 2.2 and angular 8 with package "@aspnet/signalr": "^1.1.4" i have set up a hub in Core2.2 which works fine with another angular project using the same package.

Core2.2: Startup.cs:

I finally got a SignalR Hub to work using the Microsoft.AspNet.SignalR vice the Microsoft.AspNetCore.SignalR, I was unable to get the Microsoft.AspNetCore.SignalR, no idea why. But I did get the other one to work. I am able to connect, link clients to connection id's using OnConnect and removing them using OnDisconnect. My Hub code is:

We have a bunch of repos in bitbucket. We plan to migrate to Azure Devops. When you clone a repo locally with regular git client, it works well, until you try to checkout another branch, than it complains:
