SignalR

SignalR is an ASP.NET Core library that allows server-side code to be instantly pushed to the client.

Prerequisites

• Visual Studio 2019 or higher
• Azure account (to publish SignalR service)

Steps

1. Create ASP.NET Core web application in Visual Studio and name it UnoChat.Service.

2. Add SignalR Hub to your [YourProjectName].Service project in a Hubs folder.

3. In your Startup.cs file, add your SignalR service and a CORS policy to the ConfigureServices method.

   csharpCopy

   public void ConfigureServices(IServiceCollection services)
   {
       services.AddRazorPages();
       services.AddSignalR();
       
       services.AddCors(o => o.AddPolicy(
           "CorsPolicy",
           builder => builder
               .AllowAnyOrigin()
               .AllowAnyMethod()
               .AllowAnyHeader()
       ));
   }
   

4. In your Configure method, add your CORS policy and Hubs endpoint

   csharpCopy

   app.UseCors("CorsPolicy");
   
   app.UseEndpoints(endpoints =>
   {
       endpoints.MapRazorPages();
       endpoints.MapHub<Hubs.[YourProjectHub]>("/yourProjectHub");
   });
   

You now have a SignalR service that you can use with your Uno application!
