Unity 参考 XML 映射

Question

以下代码在版本 3.5.1404 中有效，但在版本 5.0.1 中不再有效。通过 NuGet 获取最新参考资料：

在 web.config 我有：

using Microsoft.Practices.Unity.Configuration;
using Unity;

namespace ACME.Core
{
    public static class UnityCommon
    {
        static IUnityContainer _container;

        /// <summary>
        /// Returns the Common Unity Container from memory, reloads if not loaded first
        /// </summary>
        /// <param name="forceRefresh">Forces the container to be reloaded in memory</param>
        /// <returns>IUnityContainer</returns>
        public static IUnityContainer GetContainer(bool forceRefresh = false)
        {
            if (_container == null || forceRefresh)
            {
                _container = new UnityContainer();
                _container.LoadConfiguration("Default"));
            }

            return _container;
        }
    }
}

这引用了 web.config 中的 XML 映射，例如：

<unity xmlns="http://schemas.microsoft.com/practices/2010/unity">
    <assembly name="ACME.Core" />
    <namespace name="ACME.Core.DTO" />

    <container name="Default">
      <register type="IStatusRepository" mapTo="StatusRepository" />
      <register type="INoteRepository" mapTo="NoteRepository" />
    </container>
</unity>

错误：

System.Configuration.ConfigurationErrorsException occurred HResult=0x80131902 Message=An error occurred creating the configuration section handler for unity: Could not load file or assembly 'Microsoft.Practices.Unity.Configuration' or one of its dependencies. The system cannot find the file specified. Source=Unity.Configuration StackTrace: at Microsoft.Practices.Unity.Configuration.UnityContainerExtensions.LoadConfiguration(IUnityContainer container, String containerName)

at System.Configuration.TypeUtil.GetTypeWithReflectionPermission(IInternalConfigHost host, String typeString, Boolean throwOnError) at System.Configuration.RuntimeConfigurationRecord.RuntimeConfigurationFactory.Init(RuntimeConfigurationRecord configRecord, FactoryRecord factoryRecord) at System.Configuration.RuntimeConfigurationRecord.RuntimeConfigurationFactory.InitWithRestrictedPermissions(RuntimeConfigurationRecord configRecord, FactoryRecord factoryRecord) at System.Configuration.RuntimeConfigurationRecord.CreateSectionFactory(FactoryRecord factoryRecord) at System.Configuration.BaseConfigurationRecord.FindAndEnsureFactoryRecord(String configKey, Boolean& isRootDeclaredHere)

我需要以不同的方式调用 XML 配置吗？

顺便说一句，我只用了 _container.LoadConfiguration();并收到相同的错误。

在贡献者 Github (ENikS) 的帮助下解决了这个问题。

我使用的是旧命名空间问题：

<section name="unity" type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection, Microsoft.Practices.Unity.Configuration" />

但是一旦我使用了您提供的新版本，它就起作用了：

<section name="unity" type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection, Unity.Configuration"/>
