Answer 1

我刚刚将一个项目升级到 .net core 3.1，并且必须将以下行更改为

services.AddDefaultIdentity<ApplicationUser>().AddEntityFrameworkStores<DBContext>();

到

services.AddDefaultIdentity<ApplicationUser>().AddUserStore<DBContext>();

Answer 2

除了Microsoft.AspNetCore.Identity.EntityFrameworkCore按照@Kirk Larkin安装包外，我还必须安装包Microsoft.AspNetCore.Identity.UI。
