Question

我正在使用 VB.NET MVC 5 Identity 2.0 。

我一直在尝试将Startup.Auth配置为根据请求as detailed in this tutorial自动使用ApplicationDbContext，CustomUserManager和CustomRoleManager的单个实例。

我的代码如下:(减去垃圾）

Public Sub ConfigureAuth(app As IAppBuilder)
    app.CreatePerOwinContext(ApplicationDbContext.Create)
    ' Error 135 Overload resolution failed because no accessible 'CreatePerOwinContext' can be called with these arguments:
    '   Extension method 'Public Function CreatePerOwinContext(Of T)(createCallback As System.Func(Of Microsoft.AspNet.Identity.Owin.IdentityFactoryOptions(Of T), Microsoft.Owin.IOwinContext, T)) As Owin.IAppBuilder' defined in 'Owin.AppBuilderExtensions': Data type(s) of the type parameter(s) cannot be inferred from these arguments. Specifying the data type(s) explicitly might correct this error.
    '   Extension method 'Public Function CreatePerOwinContext(Of T)(createCallback As System.Func(Of T)) As Owin.IAppBuilder' defined in 'Owin.AppBuilderExtensions': Data type(s) of the type parameter(s) cannot be inferred from these arguments. Specifying the data type(s) explicitly might correct this error.

    app.CreatePerOwinContext(Of CustomUserManager)(CustomUserManager.Create)
    ' Error 136 Overload resolution failed because no accessible 'Create' accepts this number of arguments.
    ....
End Sub

但无论我做什么都会收到这些错误

重载解析失败，因为没有可访问的“Create”接受此数量的参数。

我认为这与我在VB中编写和C＃中的示例有关，尽管它激怒了我这是一个问题。我的CustomUserManager是公共类，Create方法是公共共享。

Public Shared Function Create(options As IdentityFactoryOptions(Of CustomUserManager), context As IOwinContext) As CustomUserManager
    Dim manager As CustomUserManager
    manager = New CustomUserManager(New CustomUserStore(context.Get(Of ApplicationDbContext)()))
    manager.UserValidator = New UserValidator(Of ApplicationUser, Integer)(manager)
    manager.PasswordValidator = New PasswordValidator() With {
        .RequiredLength = 6
    }
    manager.RegisterTwoFactorProvider("EmailCode",
        New EmailTokenProvider(Of ApplicationUser, Integer)() With {
            .Subject = "Security Code",
            .BodyFormat = "Your security code is: {0}"
        }
    )
    manager.EmailService = New EmailService()
    manager.SmsService = New SmsService()
    If Not options.DataProtectionProvider Is Nothing Then
        manager.UserTokenProvider = New DataProtectorTokenProvider(Of ApplicationUser, Integer)(options.DataProtectionProvider.Create("ASP.NET Identity"))
    End If
    Return manager
End Function

任何想法？任何帮助都非常感谢，干杯。

Answer 1

试试这个

Public Sub ConfigureAuth(app As IAppBuilder)
    app.CreatePerOwinContext(AddressOf ApplicationDbContext.Create)
End Sub

AddressOf运算符创建一个函数委托，指向procedurename

指定的函数

Answer 2

如果您已使用Update 3更新了visual studio 2013.这包含所有身份资料和自定义用户管理器，角色管理器等等。

使用MVC模板创建新项目，使用Visual Studio 2013选择身份验证作为个人用户帐户。然后，您将获得与使用该示例已实现的相同的所有代码。您可以使用该类和实现来解决自定义用户管理器的问题。

检查floder App_Start＆gt;＆gt; IdentityConfig.vb

我只能在你的代码中看到，你使用整数作为Id而不是字符串。如果你正确绑定EF模型的东西，这将不会是一个问题。
