如何判斷是否使用EF5

Question

我正在從EF4到EF5的Silverlight/WCF RIA服務項目。目標是.NET4.5

這是一個尖峯 - 我正在使用數據庫優先方法。即創建EDMX，然後使用域服務類嚮導

所以看起來不錯，只要有

• 的EntityFramework（5.0.0.0）
• Microsoft.ServiceModel.DomainServices.EntityFramework（ 4.0.0.0）DbDomainService在這裏
• System.Data.Entity（4.0.0.0）

而非的舊方式：

• 的EntityFramework（5.0.0.0）
• System.Data.Entity的（4.0.0.0）
• System.ServiceModel.DomainServices.EntityFramework（4.0.0.0）LinqToEntitiesDomainService在這裏

則已經把一個簡單的用戶界面上訪問2臺數據庫和它的工作

問題：這是web.config中不是我期望：

<?xml version="1.0" encoding="utf-8"?> 
<configuration> 
    <configSections> 
    <sectionGroup name="system.serviceModel"> 
     <section name="domainServices" type="System.ServiceModel.DomainServices.Hosting.DomainServicesSection, System.ServiceModel.DomainServices.Hosting, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" allowDefinition="MachineToApplication" requirePermission="false" /> 
    </sectionGroup> 
    </configSections> 
    <system.web> 
    <httpModules> 
     <add name="DomainServiceModule" type="System.ServiceModel.DomainServices.Hosting.DomainServiceHttpModule, System.ServiceModel.DomainServices.Hosting, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> 
    </httpModules> 
    <compilation debug="true" targetFramework="4.5"> 
     <assemblies> 
     <add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" /> 
     </assemblies> 
    </compilation> 
    <!-- profile stuff commented out--> 
    </system.web> 
    <system.webServer> 
    <validation validateIntegratedModeConfiguration="false" /> 
    <modules runAllManagedModulesForAllRequests="true"> 
     <add name="DomainServiceModule" preCondition="managedHandler" type="System.ServiceModel.DomainServices.Hosting.DomainServiceHttpModule, System.ServiceModel.DomainServices.Hosting, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> 
    </modules> 
    </system.webServer> 
    <system.serviceModel> 
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" /> 
    </system.serviceModel> 
    <connectionStrings> 
    <add name="DefaultConnection" connectionString="Data Source=(LocalDB)\v11.0;Initial Catalog=aspnet-BusinessApplication5.Web-20130603151851;Integrated Security=True" providerName="System.Data.SqlClient" /> 
    <add name="TestDBEntities" connectionString="metadata=res://*/Model1.csdl|res://*/Model1.ssdl|res://*/Model1.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=.\SQLEXPRESS;initial catalog=TestDB;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" /> 
    </connectionStrings> 
</configuration> 

我期待要投入：

<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=5.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" /> 
    </configSections> 

    <runtime> 
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> 
     <dependentAssembly> 
     <assemblyIdentity name="EntityFramework" publicKeyToken="b77a5c561934e089" culture="neutral" /> 
     <bindingRedirect oldVersion="0.0.0.0-5.0.0.0" newVersion="5.0.0.0" /> 
     </dependentAssembly> 
    </assemblyBinding> 
    </runtime> 

得到了配置的這些位從以下。也許他們都是codefirst特定的。 https://github.com/jeffhandley/riabooks

Answer 1

的RIA服務編譯DLL對EF 4，不EF5，所以結合重定向來使一切工作。如果/當RIA Services是開放源代碼的時候，將會有一個RiaServices.EntityFramework的新版本，它將會針對EF 5和EF 6編譯。開源的好處之一是能夠根據需要發佈儘可能多的NuGet包支持所有組合。
