将 IdentityUser 与 OAuth 一起使用时，“对象”不包含“操作”的定义

这是错误...

好的，这在我的项目中确实令人沮丧。从 ExternalLoginConfirmationViewModel 模型中删除属性后，我得到了同样的错误。

原来是ExternalLoginConfirmationViewModel.cshtm有错误，并没有停止构建进度，只在错误列表窗口中显示一次，然后所有这些错误都消失了，并在一段时间后随机出现。

确保您没有引用 ExternalLoginConfirmationViewModel.cshtm 中不存在的属性

这样：

 <div class="form-group">
        @Html.LabelFor(m => m.HomeTown, new { @class = "col-md-2 control-label" })
        <div class="col-md-10">
            @Html.TextBoxFor(m => m.HomeTown, new { @class = "form-control" })
            @Html.ValidationMessageFor(m => m.HomeTown)
        </div>
    </div>
    <div class="form-group">
        @Html.LabelFor(m => m.BirthDate, new { @class = "col-md-2 control-label" })
        <div class="col-md-10">
            @Html.TextBoxFor(m => m.BirthDate, new { @class = "form-control" })
            @Html.ValidationMessageFor(m => m.BirthDate)
        </div>
    </div>

根据 Microsoft https://connect.microsoft.com/VisualStudio/feedback/details/813133/bug-in-mvc-5-framework-asp-net-identity-modules，此问题现在似乎已修复

就我个人而言，我使用 NuGet：Update-Package 解决了我解决方案中所有包的问题。我附上了packages.config的前后供参考。

Answer 3

这个问题似乎随机出现在 MVC 5 项目中。到目前为止，我无缘无故地停止允许在局部视图中使用动态/匿名类型。

我刚刚遇到了同样的问题，_ExternalLoginsListPartial.cshtml 页面甚至回滚添加的项目更改也没有任何区别。一旦坏了，它似乎就一直坏了。

目前唯一的解决方案是不使用匿名类型，而是添加具有所需属性的强类型类。

例如像这样添加一个新类：

namespace Project.Models
{
    public class ExternalLoginViewModel
    {
        public string Action { get; set; }
        public string ReturnUrl { get; set; }
    }
}

并在部分视图中引用它

@model Project.Models.ExternalLoginViewModel

以及渲染局部视图的位置，更改为：

@Html.Partial("_ExternalLoginsListPartial", new Project.Models.ExternalLoginViewModel() { Action = "ExternalLogin", ReturnUrl = ViewBag.ReturnUrl })

Answer 4

在局部视图中使用动态类型时，我经常会遇到这种情况。

处理它的最简单方法是清理您的解决方案并重新构建。

Answer 5

这可能看起来很傻，但这是我所拥有的......

我启动了一个 Web 应用程序，它的外部登录功能在 google、facebook 和 twitter 上运行良好，然后我决定登录按钮应该看起来很漂亮，所以我使用了以下链接： http://www.beabigrockstar.com/pretty-social-login-buttons-for-asp-net-mvc-5/

之后我遇到了这个奇怪的错误（对象不包含动作定义）并来到这篇文章..

首先我尝试了 TrueBlueAussie 解决方案，但对我不起作用，然后我尝试了 Antonio Chagoury..

然后我在动作上放了一个断点：

public ActionResult ExternalLogin(string provider, string returnUrl)

然后将鼠标悬停在 provider 上，它显示 null ??当我点击 facebook 或 twitter 等时..

所以我回到 _ExternalLoginsListPartial 视图上的按钮并查看按钮，发现 name 属性有一个多余的空格：

name=" provider" value="@p.AuthenticationType"

删除那个空间对我有用！

name="provider" value="@p.AuthenticationType"

我不知道我是怎么在“提供者”这个词之前得到那个多余的空间

但是..我学到的教训是，在您遇到长时间的故障排除之前，您应该一丝不苟，仔细考虑简单的原因..

我希望这将帮助那些一直拉扯头发的人发现这只是一个拼写错误：P

Answer 6

Microsoft 正在研究这个错误。

更新： https://connect.microsoft.com/VisualStudio/feedback/details/813133/bug-in-mvc-5-framework-asp-net-identity-modules

Answer 7

我遇到了同样的问题，我可以通过删除应用程序的 bin/ 和 obj/ 文件夹来解决问题。

这会让你继续前进，但我喜欢@TrueBlueAussie 的想法，虽然我还没有尝试过。

Answer 8

您的应用程序在名为_ExternalLoginsListPartial 的局部视图中引发异常。它抛出是因为局部视图已使用不具有称为 Action 的预期属性的模型进行实例化。 此部分包含在从默认 mvc 项目模板创建的项目的登录视图中。

它是这样包含的：

        @Html.Partial("_ExternalLoginsListPartial", new { Action = "ExternalLogin", ReturnUrl = ViewBag.ReturnUrl })

在您的应用程序中，_ExternalLoginsListPartial 部分包含在某处，而没有传递具有 Action 属性的模型。 您可以搜索所有视图以查找您可能包含 _ExternalLoginsListPartial 的所有位置，并确保始终将有效模型传递给部分。
