WebAPI OData 5.0 Beta - 访问GlobalConfiguration会引发安全性错误

Question

我最近安装了WebApi OData 5.0框架的预发布版本,以使用新的$ expand支持.一切都很好,但我在App_Start上得到一个奇怪的例外.

Attempt by security transparent method
'System.Web.Http.GlobalConfiguration.get_Configuration()' 
to access security critical type 'System.Web.Http.HttpConfiguration' failed.

来源错误:

Line 12:    protected void Application_Start()
Line 13:    {
Line 14:        WebApiConfig.Register(GlobalConfiguration.Configuration); // <--
Line 15:    }

堆栈跟踪:

按照给定的顺序在包管理器控制台中运行以下命令:

Uninstall-Package Microsoft.AspNet.Mvc.FixedDisplayModes
Update-Package Microsoft.AspNet.Mvc -Pre
Update-Package Microsoft.AspNet.WebApi -Pre
Update-Package Microsoft.AspNet.WebApi.Tracing

现在,将以下更改应用于web.config:

1. 在项目的Web.config中,将app setting webpages:version的值更新为3.0.0.0

2. 在web.config中的部分运行时下,检查已配置的每个程序集的版本,并将其更新为添加到项目的程序集的版本.以下是我的web.config中的更新配置:

   <运行>
   <assemblyBinding的xmlns = "瓮:架构-微软-COM:asm.v1">
   <dependentAssembly>
   <assemblyIdentity名称= "System.Web.Helpers"公钥= "31bf3856ad364e35"/>
   <bindingRedirect oldVersion ="1.0.0.0 -3.0.0.0" NEWVERSION = "3.0.0.0"/>
   </ dependentAssembly>
   <dependentAssembly>
   <assemblyIdentity名称= "System.Web.Mvc"公钥= "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>
   <dependentAssembly>
   <assemblyIdentity名称= "的EntityFramework"公钥= "b77a5c561934e089"/>
   <bindingRedirect oldVersion = "0.0.0.0-5.0.0.0" NEWVERSION = "5.0.0.0"/>
   </ dependentAssembly>
   <dependentAssembly>
   <assemblyIdentity名称= "WebGrease"公钥= "31bf3856ad364e35"/>
   <bindingRedirect oldVersion = "0.0.0.0-1.3.0.0" NEWVERSION = "1.3.0.0"/>
   </ dependentAssembly>
   <dependentAssembly>
   <assemblyIdentity名称="系统. Web.Http"publicKeyToken ="31bf3856ad364e35"culture ="中性"/>
   <bindingRedirect oldVersion ="0.0.0.0-5.0.0.0"newVersion ="5.0.0.0"/>
   </ dependentAssembly>
   <dependentAssembly>
   <assemblyIdentity名称= "System.Net.Http.Formatting"公钥= "31bf3856ad364e35"文化= "中性"/>
   <bindingRedirect oldVersion = "0.0.0.0-5.0.0.0" NEWVERSION = "5.0.0.0"/>
   </ dependentAssembly>
   </ assemblyBinding>
   </ runtime>

从Views文件夹中打开web.config.这里有三件事需要更新:

1. 在configSections下,将Razor程序集的版本更新为3.0.0.0.

2. 更新system.web.webPages.razor部分下的主机版本,将System.Web.Mvc.MvcWebRazorHostFactory的版本更新为3.0.0.0.

3. System.web的页面部分提到了一些版本号.将所有这些更新到版本5.0.0.0

如果安装了Web API帮助页面,请检查上面的程序集配置.

我有同样的错误.我只是稍微调整了Ravi的答案,发现通过更新/安装WebApi.OData 5.0.0-rc1包来更新WebApi包对我来说效果很好.我刚刚在包管理器上运行了这些:

Update-Package Microsoft.AspNet.WebApi -Pre
Install-Package Microsoft.AspNet.WebApi.OData -Version 5.0.0

我猜测WebApi.OData包的预发行版本与新版本的WebApi包有一些依赖关系,Nuget无法将其作为依赖项进行检查.再说一遍,我在技术上是WebApi OData的新手,对包不太了解但是,是的,我可以使用$ expand和$ select功能运行项目,而不是GlobalConfiguration错误.:)
