我有两个项目,其中一个包含实体模型并充当DAL,另一个使用该模型并实现应用程序逻辑。访问单独项目中的实体模型时出错

该模型是一个类库项目,该应用程序是一个Windows窗体项目。

具有项目下面的app.config文件,并在窗体项目已经引用System.Data.Entity的,当我运行的WinForms应用程序,我得到以下错误:

附加信息:无法加载实体框架提供程序类型“System.Data.Entity.SqlServer.SqlProviderServices,EntityFramework.SqlServer”,该实体框架提供程序在具有不变名称“System.Data.SqlClient”的ADO.NET提供程序的应用程序配置文件中注册。确保使用装配限定的名称,并且该装配可用于正在运行的应用程序

您认为问题可能出在哪里?

DAL项目的的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 --> 
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" /> 
    </configSections> 
    <connectionStrings> 
    <add name="ProviderInterfaceContext" connectionString="metadata=res://*/ProviderInterfaceModel.csdl|res://*/ProviderInterfaceModel.ssdl|res://*/ProviderInterfaceModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=192.168.2.12;initial catalog=ProviderInterface;user id=--;password=---;multipleactiveresultsets=True;application name=EntityFramework&quot;" providerName="System.Data.EntityClient" /> 
    </connectionStrings> 
    <entityFramework> 
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework"> 
     <parameters> 
     <parameter value="mssqllocaldb" /> 
     </parameters> 
    </defaultConnectionFactory> 
    <providers> 
     <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" /> 
    </providers> 
    </entityFramework> 
    <system.serviceModel> 
    <client> 
     <endpoint address="" 
      binding="basicHttpBinding" 
      contract="PrizeServiceSoap" name="PrizeServiceSoap" /> 
    </client> 
    </system.serviceModel> 
</configuration> 

的的WinForms的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 -->

固定。

添加了对EntityFramework 6.0和EntityFramework.SqlServer的引用,现在一切正在运行。
