Hey dev community! 👋

I've just published a sample repository demonstrating how to implement real-time notifications with SignalR in ASP.NET Core. I built this while exploring cross-tab communication possibilities, and I thought it might be useful for others too.

What's Inside?

The repository contains a clean implementation showing how to:

• Set up SignalR in ASP.NET Core
• Handle real-time notifications across multiple browser tabs
• Manage automatic reconnection
• Implement animated notifications

Key Features

public class NotificationHub : Hub
{
    public override async Task OnConnectedAsync()
    {
        string userId = Context.User.FindFirst("uid").Value;
        await Groups.AddToGroup(Context.ConnectionId, userId);
        await base.OnConnectedAsync();
    }

    public async Task SendNotification(string message)
    {
        await Clients.All.SendAsync("ReceiveNotification", message);
    }
}

The implementation is straightforward yet powerful. It handles multiple tabs seamlessly, making it perfect for modern web applications.

Where to Find It?

• 📦 Repository: GitHub - SignalR.NET
• 📝 Detailed Tutorial (Italian): cosminirimescu.com/signalr-in-asp-net-core

While the tutorial is in Italian, the code and commit messages are in English. If you're interested in the implementation details, I've written a comprehensive guide on my blog.

Tech Stack

• ASP.NET Core 8.0
• SignalR
• JavaScript
• CSS3 for animations
