无法解析尝试调用主机Unity的构造函数

当我试图实例化我的基类实例时,我得到一个错误:

无法解析带有“failedException”参数的构造函数

我当前没有为基类型使用接口,并且我的类实例正在继承基类型类。我是新来的统一和DI,所以我想它的东西我可能忘了。

ExeConfigurationFileMap map = new ExeConfigurationFileMap();
map.ExeConfigFilename = "Unity.Config";
Configuration config = ConfigurationManager.OpenMappedExeConfiguration(map,  ConfigurationUserLevel.None);
UnityConfigurationSection section = (UnityConfigurationSection)config.GetSection("unity");
IUnityContainer container = new UnityContainer();
section.Containers.Default.Configure(container);
//Throws exception here on this
BaseCalculatorServer server = container.Resolve<BaseCalculatorServer>();

以及Unity.Config文件

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

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

    <unity>
        <containers>

            <container>

                <types>
                    <type name ="CalculatorServer" type="Calculator.Logic.BaseCalculatorServer, Calculator.Logic" mapTo="Calculator.Logic.CalculateApi, Calculator.Logic"/>
                </types>

            </container>

        </containers>
    </unity>

</configuration>

基类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Transactions;
using Microsoft.Practices.Unity;
using Calculator.Logic;

namespace Calculator.Logic
{

    public class BaseCalculatorServer : IDisposable
    {
        public BaseCalculatorServer(){}
        public CalculateDelegate Calculate { get; set; }
        public CalculationHistoryDelegate CalculationHistory { get; set; }


        /// <summary>
        /// Performs application-defined tasks associated with freeing, releasing, or     resetting unmanaged resources.
        /// </summary>
        public void Dispose()
        {
            this.Dispose();
        }
    }
}

实施

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Calculator.Logic;
using System.ServiceModel;
using System.ServiceModel.Configuration;
using Microsoft.Practices.Unity;

namespace Calculator.Logic
{
    public class CalculateApi:BaseCalculatorServer
    {
        public CalculateDelegate Calculate { get; set; }
        public CalculationHistoryDelegate CalculationHistory { get; set; }
    }
}

是的,基类和实现都在同一个名称空间中,这是一些设计方面的东西,一旦我开始工作就会改变。 哦,还有一个更详细的错误

解析依赖项失败,type=“Calculator.Logic.BaseCalculatorServer”,name=“”。异常消息是:当前生成操作(生成键build key[Calculator.Logic.BaseCalculatorServer,null])失败:无法解析属性“Calculate”的值(策略类型(策略,索引3)
