Describe the bug

I created a new Project using .NET 9 Preview 3

Blazor Web App -> Individual Accounts Identity -> Server Interactivity -> Global Interactivity mode

Once the project is created if i do .AddRoles in Program.cs as shown in the image it gives exception

Default that project comes with is

builder.Services.AddIdentityCore<ApplicationUser>(options => options.SignIn.RequireConfirmedAccount = true)
    .AddEntityFrameworkStores<ApplicationDbContext>()
    .AddSignInManager()
    .AddDefaultTokenProviders();

What i added to add roles is below

builder.Services.AddIdentityCore<ApplicationUser>(options => options.SignIn.RequireConfirmedAccount = true)
    .AddEntityFrameworkStores<ApplicationDbContext>()
    .AddSignInManager()
    .AddDefaultTokenProviders();

---

It also throws an exception if i try to change (might be another bug)

builder.Services.AddIdentityCore<ApplicationUser>(options => options.SignIn.RequireConfirmedAccount = true)
    .AddEntityFrameworkStores<ApplicationDbContext>()
    .AddRoles<IdentityRole>()   
    .AddSignInManager()
    .AddDefaultTokenProviders();

to

builder.Services.AddIdentity<ApplicationUser,IdentityRole>(options => options.SignIn.RequireConfirmedAccount = true)
    .AddEntityFrameworkStores<ApplicationDbContext>()
    .AddSignInManager()
    .AddDefaultTokenProviders();

Expected Behavior

It should add roles to the project.

Steps To Reproduce

Create a new Blazor App using following

Blazor Web App -> Individual Accounts Identity -> Server Interactivity -> Global Interactivity mode

Once the project is created if i do .AddRoles in Program.cs as shown in the image it gives exception
