Hi @打玻璃,

You can refer the code below.

@using Microsoft.AspNetCore.Http;
@inject IHttpContextAccessor HttpContextAccessor;

@{
    string? connectionId = HttpContextAccessor?.HttpContext?.Connection.Id;
    var Claims = HttpContextAccessor.HttpContext.User.Claims;
}

Thanks Jason. I am new to Razor Pages and web development in general. So I am sure there are lots of issues with the following as this is just a learning exercise for me. But your suggestion worked. I managed to access the session data in the _Layout.cshtml file by adding:

builder.Services.AddHttpContextAccessor();

to the services section of the Program.cs file and the following to the top of the _Layout.cshtml file:

@using Microsoft.AspNetCore.Http;
@inject IHttpContextAccessor HttpContextAccessor;
@{
    string loggedIn = HttpContextAccessor.HttpContext.Session.GetString("LoggedIn") ?? "false";
}
