IServiceCollection does not contain definition of AddDefaultIdentity

I am getting the following error when I try to call AddDefaultIdentity in an ASP.NET WebAPI project:

'IServiceCollection' does not contain a definition for 'AddDefaultIdentity' and no accessible extension method 'AddDefaultIdentity' accepting a first argument of type 'IServiceCollection' could be found (are you missing a using directive or an assembly reference?)

I reproduced the issue when I installed Microsoft.AspNetCore.Identity.UI package higher than version 3.0 in a 3.0 project. Note: AddDefaultIdentity extension method is used to add the default UI service for Razor Pages and MVC.

You could use AddIdentity instead of AddDefaultIdentity like below:

services.AddIdentity<ApplicationUser,IdentityRole>()
            .AddEntityFrameworkStores<ApplicationDbContext>();

If you want to use AddDefaultIdentity, you should update the version of Microsoft.AspNetCore.Identity.UI to 3.0.

For the difference between AddDefaultIdentity and AddIdentity , refer to https://medium.com/@xsoheilalizadeh/asp-net-core-identity-deep-dive-stores-e0e54291b51d
