知道为什么我会出现这个错误吗？ 错误信息 --> "IServiceCollection不包含AddDefaultIdentity的定义"
我正在从.NET Core v1.1迁移到v3.1。

好的，通过添加 "Microsoft.AspNetCore.Identity.UI "的NuGet包来帮助我。 现在我又遇到了另一个错误。 :- 我无法理解这个错误。
services.AddDefaultIdentity<ApplicationUser>()
.AddRoles<IdentityRole<Guid>>()
.AddEntityFrameworkStores<ApplicationContext, Guid>()
.AddDefaultTokenProviders();
第一行的错误现在已经消失了。 但是现在新的错误出现在第三行，"AddEntityFrameworkStore()"。 错误信息是--> "IdentityBuilder "不包含 "AddEntityFrameworkStores "的定义& 找不到可访问的扩展方法 "AddEntityFrameworkStores "接受第一个参数类型为 "IdentityBuilder "的方法（你是在使用指令还是在使用汇编引用？
我甚至不知道这个 "AddEntityFrameworkStores "是从哪个NuGet包里出来的&从版本1到3.1有什么变化。
你需要在程序中添加一个对 Microsoft.AspNetCore.Identity.UI nuget包 为了使用 AddDefaultIdentity. 但如果您不想迁移到Identity Razor类库，我认为您仍然可以使用 .AddIdentity<ApplicationUser, IdentityRole>() 的核心3.1中。 如果你确实想迁移到RCL，2.0到2.1的迁移文档可能是一个很好的起点。https:/docs.microsoft.comen-usaspnetcoremigration20_21?view=aspnetcore-3.1#changes-to-authentication-code(认证代码变更)

我已经把几个网站从1.1迁移到3.1，我发现最简单的方法是这样做的。
要让它正常工作还需要很多时间，否则你就需要从1.x到2.0的迁移文档开始，一直到3.0到3.1的文档。
