c#-简单的注入器依赖项解析错误-无法加载文件或程序集System.Web.Http

我正在遵循洋葱体系结构,并在DependencyResolution项目中使用简单的注射器.这是我的架构：

1-Core
     - Domain Classes
     - Repository Interfaces
     - Service Interfaces
2-Infrastructure
     - Data
     - Dependency Resolution
     - Repository Interfaces Implementation
     - Service Interfaces Implementation
3-WebApi
     - Web Api Project
4-WebClient
     - My AngularJs App
5-Test
     - Test Project

StartUp.cs

public partial class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            // Here I am getting error at runtime.
            SimpleInjectorInitializer.Initialize(app);
            ConfigureAuth(app);
        }
    }

SimpleInjectorInitializer.Initialize

public static Container Initialize(IAppBuilder app)
        {
            var container = GetInitializeContainer(app);

            // This is an extension method from the integration package.
            container.RegisterWebApiControllers(GlobalConfiguration.Configuration);

            container.Verify();

            GlobalConfiguration.Configuration.DependencyResolver =
                new SimpleInjectorWebApiDependencyResolver(container);

            return container;
        }

在这里,我添加了对从WebApi项目中获取的System.Web,System.Web.Http,System.Web.Http.Host的引用.

我将DependencyResolution项目的输出路径放入WebApi bin,并在web.config中设置owinstart的值.

这是我得到的错误：

An exception of type ‘System.IO.FileLoadException’ occurred in
Infrastructure.DependencyResolution.dll but was not handled in user
code

Additional information: 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)

编辑：

这是App.Config：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
  </configSections>
  <runtime>

        <bindingRedirect oldVersion="0.0.0.0-5.2.3.0" newVersion="5.2.3.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>

解决方法:

您可能在应用程序的配置文件中缺少绑定重定向.在大多数情况下,NuGet软件包管理器会为您正确设置绑定重定向,有时可能会这样做.

您在配置文件中所需的绑定重定向如下所示：

<?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-{version}" newVersion="{version}"/>
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>

请注意,您需要将{version}占位符替换为您所引用的实际版本.
