尝试通过安全透明方法“Microsoft.Web.Helpers.PreApplicationStartCode.Start()”访问安全关键方法答案

【问题标题】：Attempt by security transparent method 'Microsoft.Web.Helpers.PreApplicationStartCode.Start()' to access security critical method尝试通过安全透明方法“Microsoft.Web.Helpers.PreApplicationStartCode.Start()”访问安全关键方法

【问题描述】：

我的解决方案中有两个 MVC 网站，已转换为 MVC5。对于特定的测试，我需要两个站点都运行，因为一个站点通过 Web API 与另一个站点通信。他们正在使用 IIS Express 运行。

当我在 Visual Studio (2012) 中启动其中一个并访问启动的那个时，一切正常。当我尝试访问另一个时，我收到以下消息：

尝试通过安全透明方法“Microsoft.Web.Helpers.PreApplicationStartCode.Start()”访问安全关键方法“System.Web.WebPages.Razor.WebPageRazorHost.AddGlobalImport(System.String)”失败。

根据其他答案的建议，我更新了所有软件包并从其中一个软件包中卸载了 DotNetOpenAuth 软件包，但没有任何结果。

这是站点 #1 的package.config：

我还能尝试什么？

Web API 调用（一个站点调用另一个站点）：

if (SettingsHelper.GetCurrentSettings().IntegratedToFederated)
{
    // Report Federated
    var pointsGranted = new APIPointsGrantedModel();
    pointsGranted.CustomerId = customerPointsPerShop.Customer.ControlKey;
    pointsGranted.ShopId = (Guid)customerPointsPerShop.Shop.ControlKey;
    pointsGranted.Amount = customerPointsPerShop.Points;
    pointsGranted.Timestamp = DateTime.Now;

    HttpClient aClient = new HttpClient();
    var website = context.Settings.FirstOrDefault().FederatedWebsite;
    Uri theUri = new Uri(website + "/api/APIShops/PointsGranted");
    HttpResponseMessage aResponse = await aClient.PostAsync(theUri, StringContentHelper.BuildStringContent(pointsGranted, pointsGranted.GetType()));

    if (aResponse.IsSuccessStatusCode)
    {
        var responseContent = await aResponse.Content.ReadAsAsync<APIPointsGrantedModel>();
        // Read the response and perform some business logic
    }
    else
    {
        String failureMsg = "HTTP Status: " + aResponse.StatusCode.ToString() + " - Reason: " + aResponse.ReasonPhrase;
        this.FlashError(failureMsg);
        // TODO: Register in log.
    }

【问题讨论】：

请在您的帖子中包含您的 Web API 调用（来自客户端）。另外，请解释一下：您是否在两种情况下都跨域提出请求，仅在 1 中，两者都没有？请澄清。
恐怕这与答案无关，但我编辑了我的问题以澄清。两个站点都发送命令，一个到另一个，因为一个是“联盟”的主站点，另一个由这个主站点控制。
可能不相关。每次我看到跨域请求时，我都会担心同源策略限制。所以，我想确认您启用了 CORS
啊，好的。感谢您的关注；）
抱歉，我的意思是作为一个问题：您是否在 Web-API 提供程序上启用了 CORS？

标签： c# asp.net asp.net-mvc nuget-package

【解决方案1】：

注意：Microsoft-Web-Helpers 已替换为 Microsoft.AspNet.WebHelpers。您应该先删除旧包，然后再安装较新的包。

我打开了 NuGet 包管理器并安装了包 Microsoft.AspNet.WebHelpers，一切都开始工作了。请注意，当您创建新的 MVC 5 应用程序并尝试合并 SimpleSecurity 或 SimpleMembership 时，您将遇到同样的问题，因为默认情况下未安装 Microsoft.AspNet.WebHelpers。必须存在 SimpleMembership 才能正确运行。

我验证了参考应用程序中的所有功能在升级后都可以正常工作。甚至使用 Postal 生成电子邮件也有效，由于 Razor 的升级，我也不确定。

我需要对 SimpleSecurity 程序集进行的一项更改是删除过滤器 AuthorizeAttribute 和 BasicAuthorizeAttribute 并将它们放在单独的程序集中。我这样做是因为它们依赖于 MVC 和 Web API 程序集。所以现在有一个 MVC 版本和另一个 MVC 5 版本。

参考这个链接： http://ctsoftr.com/upgrading-from-asp-net-mvc-4-to-5/

【讨论】：

请注意，这些步骤之前已完成，正如我在两个网站上发布的packages.config 所示。当我尝试同时访问这两个站点时，问题就开始了。调试中的一个正常工作，而另一个有错误。
@CiganoMorrisonMendez - 但错误显示 Microsoft.Web.Helpers，你应该已经删除的包......嗯......这不是给你敲响了警钟吗？
@ErikFunkenbusch 似乎是一个错误或类似的东西。

【解决方案2】：

我收到了同样的错误信息，它与一个已更改但未在各处正确更新的包有关（不知道为什么，不知道如何，您可以想象这个错误带来的快乐）..我扔掉了我的包文件夹并重建了项目等等……仅仅几个小时后，我又开始编码了

【讨论】：

【解决方案3】：

首先，如果可能，我会建议使用 Visual Studio 2013 for MVC 5。

似乎您已经尝试了很多事情，但我重申了一些必须检查的事情（因为它可以帮助遇到相同问题的其他人）并且可能是问题的原因：

更新所有 nuget 包。（通过 packages.config 似乎你已经做到了）
在global.asax，更改：

WebApiConfig.Register(GlobalConfiguration.Configuration);

到

GlobalConfiguration.Configure(WebApiConfig.Register);

删除使用包管理器中的以下命令安装的以下任何 ASP.NET NuGet 包：

Uninstall-Package -Id Microsoft.AspNet.WebPages.Administration

Uninstall-Package -Id Microsoft-Web-Helpers

Uninstall-Package -Id Microsoft.AspNet.Mvc.FixedDisplayModes

（看来你也这样做了）。

在 web.config 中确保这些更改存在：

在<runtime>/<assemblyBinding> 部分，确保newVersion 存在正确：

<runtime>
  <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
    <!--Two elements removed for Clarity -->
    <dependentAssembly>
      <assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35" />
      <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
    </dependentAssembly>
    <dependentAssembly>
      <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
      <bindingRedirect oldVersion="1.0.0.0-5.0.0.0" newVersion="5.0.0.0" />
    </dependentAssembly>
    <dependentAssembly>
      <assemblyIdentity name="System.Web.WebPages" publicKeyToken="31bf3856ad364e35" />
      <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
    </dependentAssembly>
    <!--WebGrease element removed for Clarity -->
  </assemblyBinding>

5。在 web.config 中找到 <appSettings> 部分，并将 webpages:version 从 2.0.0.0.0 更新为 3.0.0.0，如下所示：

 <appSettings>
    <add key="webpages:Version" value="3.0.0.0" />
    <add key="webpages:Enabled" value="false" />
    <add key="PreserveLoginUrl" value="true" />
    <add key="ClientValidationEnabled" value="true" />
    <add key="UnobtrusiveJavaScriptEnabled" value="true" />
  </appSettings>

6。删除 Full 以外的任何信任级别，例如：

<securityPolicy>
   <!--<trustLevel name="Medium"  policyFile="web_mediumtrust.config"/>-->
</securityPolicy>

7.更新 Views 文件夹下的 web.config 文件

将所有包含System.Web.Mvc 的元素从“4.0.0.0”版本更新为“5.0.0.0”版本。

-->
    <pages
        validateRequest="false"
        pageParserFilterType="System.Web.Mvc.ViewTypeParserFilter, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"
        pageBaseType="System.Web.Mvc.ViewPage, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"
        userControlBaseType="System.Web.Mvc.ViewUserControl, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
        <controls>
            <add assembly="System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" namespace="System.Web.Mvc" tagPrefix="mvc" />
        </controls>
    </pages>
</system.web>`

将所有包含System.Web.WebPages.Razor 的元素从版本“2.0.0.0”更新到版本“3.0.0.0”。如果此部分包含System.Web.WebPages，请将这些元素从版本“2.0.0.0”更新为版本“3.0.0.0”

<configuration>
    <configSections>
        <sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
            <section name="host" type="System.Web.WebPages.Razor.Configuration.HostSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
            <section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
        </sectionGroup>
    </configSections>`

如果您在上一步中删除了 Microsoft-Web-Helpers NuGet 包，请在 PMC 中使用以下命令安装 Microsoft.AspNet.WebHelpers：
```
Install-Package -Id  Microsoft.AspNet.WebHelpers
```

如果您的应用使用User.IsInRole() 方法，请将以下内容添加到Web.config 文件中。

<system.webServer>
    <modules>
        <remove name="RoleManager" />
    </modules>
</system.webServer>`

从项目文件中删除 MVC 4 项目类型 GUID。
- 在解决方案资源管理器中，右键单击项目名称，然后选择卸载项目。
- 右键单击项目并选择编辑ProjectName.csproj。
- 找到 ProjectTypeGuids 元素，然后删除 MVC 4 项目 GUID {E3E379DF-F4C6-4180-9B81-6769533ABE47}。
- 保存并关闭打开的项目文件。
- 右键单击项目并选择重新加载项目。
希望它会有所帮助。

【讨论】：

感谢您的回答，但我在两个项目中都完成了您的所有步骤（项目已从 MVC4 迁移到 MVC5），显然问题不在于依赖项或配置。似乎与默认的 machine.config 条目有关。

【解决方案4】：

这是完整的官方迁移指南：

How to Upgrade an ASP.NET MVC 4 and Web API Project to ASP.NET MVC 5 and Web API 2

主要变化包括：

Medium Trust 不再可用（现在应该使用 Full Trust）；
现在应该使用与 MVC 5 和 Web API 2 兼容的包。
