OWIN/Identity 2.0 -将pk从字符串更改为GUID

本文关键字：字符串 GUID pk Identity OWIN | 更新日期: 2023-09-27 18:15:55

我试图改变asp.net身份的pk系统从数据库nvarchar(128) ->唯一标识符和代码从字符串-> Guid。在这篇基于将pk更改为int32的文章之后，我似乎只有一个问题无法解决。

在我的Startup.Auth.cs类中，我更改了以下

app.UseCookieAuthentication(new CookieAuthenticationOptions
        {
            AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
            LoginPath = new PathString("/Account/Login"),
            Provider = new CookieAuthenticationProvider
            {   //error on the line below
                OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, ApplicationUser, Guid>(TimeSpan.FromMinutes(20), (manager, user) => user.GenerateUserIdentityAsync(manager), (identity) => Guid.Parse(identity.GetUserId()))
            }
        });

，我得到两个错误，我不能理解。Identity的结构让我对这么多泛型感到困惑。我理解它说它正在接收错误的参数类型，但我不知道如何补救这个问题。

错误1最佳重载方法匹配"Microsoft.AspNet.Identity.Owin.SecurityStampValidator.OnValidateIdentity (System.TimeSpan,系统。Func>,System.Func)"一些无效参数

错误2参数2:无法从'lambda表达式'转换为的系统。Func>的

谁能提供一点见解?
