我正在关注洋葱架构并在DependencyResolution项目中使用simple injector
。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;
}
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项目输出的路径放到WebApi bin中,并在web.config
中设置owinstart的值。
以下是我遇到的错误:
类型' System.IO.FileLoadException'的例外情况发生在 Infrastructure.DependencyResolution.dll但未在用户中处理 代码
其他信息:无法加载文件或程序集 ' System.Web.Http,Version = 4.0.0.0,Culture = neutral, 公钥= 31bf3856ad364e35'或其中一个依赖项。该 定位程序集的清单定义与程序集不匹配 参考。 (HRESULT异常:0x80131040)
修改
这是App.Config:

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包管理器会为您正确设置绑定重定向,因为有时它无法执行此操作。
配置文件中需要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,您需要替换您引用的实际版本的{version}
占位符。

您确定在使用依赖注入的整个项目中使用相同版本的SimpleInjector吗?我遇到了类似的错误,我注意到在一个项目中使用了SimpleInjectors旧版本。在我通过nuget将SimpleInjector更新为新版本后,它开始工作。
