我需要以下绑定：

我的设置如下。

一个网站项目。引用该网站的云服务 Webrole。从 webrole 启动方法调用并启动 Owin 自托管服务的类库。

    var endpoint = RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["CompositeServiceEndpoint"];
    string baseUri = string.Format("{0}://{1}",
        endpoint.Protocol, endpoint.IPEndpoint);
    Trace.TraceInformation(String.Format("Starting OWIN at {0}", baseUri));
    _app = WebApp.Start(new StartOptions(url: baseUri), (appbuilder) => new Startup().Configuration(appbuilder, CompositeWebRole.DependencyResolver));

这就是失败的原因，它尝试加载 4.0。

Plugin Initialization 'Composite.WindowsAzure.Management.Plugins.CompositeManagementPlugin': System.IO.FileLoadException: Could not load file or assembly 'System.Web.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
File name: 'System.Web.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'

我尝试在网站项目的 app.config 和 web.config 中添加程序集绑定。这不是我应该放文件的地方吗？

更新

我已经验证，登录到远程桌面， f:/approot/ 有 web.config 里面的绑定。

完整的错误是：

Plugin Initialization 'Composite.WindowsAzure.Management.Plugins.CompositeManagementPlugin': System.IO.FileLoadException: Could not load file or assembly 'System.Web.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

当我在模拟器中运行它时没有问题。

根据您使用的 SDK，我在使用 Azure SDK 2.3 的时候遇到了这个问题。

由于现在使用完整的 IIS，WebRole 无法看到您的常规 Web.config 文件或 app.config 文件。Visual Studio 应该自动将文件放在 bin 文件夹中，但由于某些原因，这对我不起作用。如果是这种情况，请执行以下操作：

创建一个新的 .config 文件，命名它

"yourprojectname".dll.config

放入项目的根目录并为您需要的所有引用插入程序集绑定代码，例如：

<?xml version="1.0" encoding="utf-8"?>
 <configuration>
  <runtime>
   <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
       <dependentAssembly>
         <assemblyIdentity name="System.Web.Http" publicKeyToken="31bf3856ad364e35" culture="neutral" />
         <bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.0" />
       </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>

然后部署项目，角色将看到新的配置文件。希望这可以帮助某人。

我找不到真正问题的解决方案。

我最终从 Unity WebAPI boostrapper 获取代码，因为这是引入一些 4.0.0.0 对 webapi 引用的依赖项。踢出这一点，只是在我自己的 dll 中实现而不使用统一 web api bootsrapper 解决了我的问题。
