我几乎放弃并尝试其他DI解决方案。请，任何帮助将被罚款......
I am almost giving up and trying another DI solution. Please, any help will be fine...

我的Global.asax：
My Global.asax:

using System.Web.Mvc;
using System.Web.Optimization;
using System.Web.Routing;
using Biblioteca.Dependency;
namespace Biblioteca

BundleConfig.RegisterBundles(BundleTable.Bundles);
//Below is a static variable to take the unity container
//which is on a dependency project
Global.Container = Bootstrapper.Initialise();

我的引导程序类：
My Bootstrapper class:

using Microsoft.Practices.Unity.Configuration;
using System.Configuration;
using System.Web.Mvc;
using Unity.Mvc4;
namespace Biblioteca

var unitySection = (UnityConfigurationSection)configuration.GetSection("unity");
//*** this line is firing the error !!! ****
var container = new UnityContainer().LoadConfiguration(unitySection);

我的依赖项目静态类：
My Dependency project static class:

这是MVC 4项目我的UI模型类文件。我使用的4.5框架。
My UI model class file on MVC 4 project. I am using 4.5 framework.

{
var categoriaBO = Global.Resolve<IManterCategoriaBO>();
categoriaBO.GetById(1);
}
}
}
}
我觉得一切都在正确的道路。但是，我不能看到这个作品的DI，因为我只是在映射过程得到了一个错误，在下面一行在我的引导程序类，BuildUnityContainer方式：
I think everything is in the right way. But, I can´t see this DI works cause I got an error just in the mapping process, in line below on my Bootstrapper class, BuildUnityContainer method:
VAR集装箱=新UnityContainer（）LoadConfiguration（unitySection）;
var container = new UnityContainer().LoadConfiguration(unitySection);
该错误是：
键入名称或别名Biblioteca.Contracts.IManterCategoriaBO可能
无法得到解决。请检查您的配置文件并验证该
类型名称。
The type name or alias Biblioteca.Contracts.IManterCategoriaBO could not be resolved. Please check your configuration file and verify this type name.
我有双重检查我的所有类和我来说，他们是ok了。抑或是缺少什么？
I have double checked all my classes and for me, they are ok. Or is it missing anything ?
我需要帮助，因为我有一个很短的时间来照顾这....
I need help, cause I have a short time to take care of this....

推荐答案
这个问题在你的配置文件。你是混合两个概念的一些不正确的语法。
The problem is in you config file. You are mixing two concepts with some incorrect syntax.
的＆LT;装配... /＆GT; 和＆LT;命名空间... /＆GT; 节点提供了一个集和命名空间的搜索顺序当你的＆LT;注册... /＆GT; 节点包含自身不能找到一个类型。如果无法找到一个类型，它通过搜索的所有组合[命名空间]。键入[装配] 。这里就是错误的是：它不会搜索键入[装配] 。如果任何＆LT;命名空间... /方式＆gt; 中定义的节点，它不会尝试只追加装配
The <assembly... /> and <namespace ... /> nodes provide an assembly and namespace search order when your <register ... /> node contains a type that cannot be found by itself. If a type cannot be found, it searches through all combinations of [namespace].Type, [assembly]. Here's where the error is: it does NOT search for Type, [assembly]. If any <namespace ... /> nodes are defined, it does NOT try appending only the assembly.
所以你的＆LT;注册类型=Biblioteca.Contracts.IManterCategoriaBOmapTo =Biblioteca.Business.ManterCategoriaBO/＆GT; 节点类型 Biblioteca.Contracts.IManterCategoriaBO 不含有该组件，因此它不能被发现。因此，它需要做一个搜索。你没有指定＆LT;命名空间... /＆GT; 节点，所以它会首先尝试 Biblioteca.Biblioteca.Contracts.IManterCategoriaBO，藏书。注意重复的藏书名。
So your <register type="Biblioteca.Contracts.IManterCategoriaBO" mapTo="Biblioteca.Business.ManterCategoriaBO" /> node has the type Biblioteca.Contracts.IManterCategoriaBO which does not contain the assembly, so it cannot be found. Therefore, it needs to do a search. You did specify <namespace ... /> nodes, so it will first try Biblioteca.Biblioteca.Contracts.IManterCategoriaBO, Biblioteca. Notice the duplicate Biblioteca name.
下面是一个更正配置文件。
Here's a corrected config file.
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="unity" type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection, Microsoft.Practices.Unity.Configuration" />
</configSections>
<unity xmlns="http://schemas.microsoft.com/practices/2010/unity">
<assembly name="Biblioteca" />
<assembly name="Biblioteca.Contracts" />
<assembly name="Biblioteca.Business" />
<namespace name="Biblioteca" />
<namespace name="Biblioteca.Contracts" />
<namespace name="Biblioteca.Business" />
<container>
<register type="IManterCategoriaBO" mapTo="ManterCategoriaBO" />
<!-- Or this works -->
<!--<register type="Biblioteca.Contracts.IManterCategoriaBO, Biblioteca" mapTo="Biblioteca.Business.ManterCategoriaBO, Biblioteca" />-->
</container>
</unity>
</configuration>
