How to add Identity Authentication Cookie Timeout in ASP.NET Core 2

Question

I have an existing production ASP.NET Core 1.1 project that I have upgraded to ASP.NET Core 2.

I set the ASP.NET Core identity authentication cookie like this in ASP.NET Core 1.1 to 2 hours

public void ConfigureServices(IServiceCollection services)
{

    services.AddIdentity<ApplicationUser, ApplicationRole>(options =>
    {
        options.Cookies.ApplicationCookie.CookieName = "MyApp";
        options.Cookies.ApplicationCookie.ExpireTimeSpan = TimeSpan.FromMinutes(120);
     })
    .AddEntityFrameworkStores<MyDbContext, Guid>()
    .AddDefaultTokenProviders();

However in ASP.NET 2.0 Core the Cookies property has been removed from the AddIdentity option

If you want to tweak Identity cookies, they're no longer part of IdentityOptions. You will have use services.ConfigureApplicationCookie like this-

    public void ConfigureServices(IServiceCollection services)
    {
        ....
        services.ConfigureApplicationCookie(options => {
            options.CookieName = "MyApp";
            options.ExpireTimeSpan = TimeSpan.FromMinutes(120);
        });
        ....
    }

Note: CookieName property is obsolete and will be removed in a future version. The recommended alternative is Cookie.Domain.
