'FileLoadException: Could not load file or assembly 'Microsoft.AspNetCore.SignalR.Core

I'm creating a .net core console application where some of the libraries are using SignalR.
I have installed "Microsoft.AspNetCore.SignalR.Core" from nuget package manager and also added the same in Program.cs file as below.

class Program
    {
        static void Main(string[] args)
        {
            var host = CreateDefaultBuilder().Build();
            using IServiceScope serviceScope = host.Services.CreateScope();
            IServiceProvider provider = serviceScope.ServiceProvider;
            var workerInstance = provider.GetRequiredService<Worker>();
            workerInstance.DoWork();
            host.Run();
        }

        static IHostBuilder CreateDefaultBuilder()
        {
            return Host.CreateDefaultBuilder()
                .ConfigureAppConfiguration(app =>
                {
                    app.AddJsonFile("appsettings.json");
                })
                .ConfigureServices(services =>
                {                    
                    services.AddSignalRCore();
                    services.AddSignalR();
                });
        }
}

I have added AddSignalRCore in the ConfigurationServices. Is there any anywhere else I need to add the reference or is there any other step missing? Because when I run the code, it gives an error:

FileLoadException: Could not load file or assembly 'Microsoft.AspNetCore.SignalR.Core, Version=3.1.0.0, Culture=neutral, PublicKeyToken=XXXXXXXXXXXXXXXX'. The located assembly's manifest definition does not match the assembly reference. (0x80131040)

Can you take a screenshot of your csproj package management file? I did not find Microsoft.AspNetCore.SignalR.Core, Version=3.1.0.0. This version.

How you want to use SignalR in combination with asp.net core can download these packages:

Server NuGet Package?

Microsoft.AspNetCore.App

Client NuGet packages?

Microsoft.AspNetCore.SignalR.Client
