ASP.NET MVC 4 + Entity Framework 6 + SQL Compact Edition 4.0部署无需安装

Question

我试图在安装了iis的Windows 7的干净安装上部署使用Entity Framework 6(Code First)和SQL Compact 4.0的基本MVC 4应用程序(未安装mvc 4和sql compact 4.0).

我在db项目上安装了以下nuget包:

• EntityFramework(版本6.0.0-alpha2)
• EntityFramework.SqlServerCompact(Version 6.0.0-alpha2)
• Microsoft.AspNet.Providers(版本1.2)
• Microsoft.AspNet.Providers.Core(1.2版)
• Microsoft.SqlServer.Compact(版本4.0.8876.1)

在web.config中,我得到了以下配置:

<connectionStrings>
  <add name="[Name]" connectionString="Data Source=|DataDirectory|[FileName].sdf" providerName="System.Data.SqlServerCe.4.0" />
</connectionStrings>  

......................

<entityFramework>
  <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework">
     <parameters>
        <parameter value="System.Data.SqlServerCe.4.0" />
     </parameters>
  </defaultConnectionFactory>
  <providers>
      <provider invariantName="System.Data.SqlServerCe.4.0" type="System.Data.Entity.SqlServerCompact.SqlCeProviderServices, EntityFramework.SqlServerCompact, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
  </providers>
</entityFramework>

Bin文件夹(sql ce文件位于amd64和x86文件夹中:

• [AMD64]
• [86]
• Antlr3.Runtime.dll
• DotNetOpenAuth.AspNet.dll
• DotNetOpenAuth.Core.dll
• DotNetOpenAuth.OAuth.Consumer.dll
• DotNetOpenAuth.OAuth.dll
• DotNetOpenAuth.OpenId.dll
• DotNetOpenAuth.OpenId.RelyingParty.dll
• EntityFramework.dll
• EntityFramework.SqlServer.dll
• EntityFramework.SqlServer.xml
• EntityFramework.SqlServerCompact.dll
• EntityFramework.SqlServerCompact.xml
• EntityFramework.xml
• Microsoft.Web.Infrastructure.dll
• Microsoft.Web.WebPages.OAuth.dll
• Newtonsoft.Json.dll
• ShipMedProto.DB.dll
• ShipMedProto.DB.pdb
• ShipMedProto.Web.dll
• ShipMedProto.Web.pdb
• System.ComponentModel.DataAnnotations.dll
• System.Data.DataSetExtensions.dll
• System.Data.SqlServerCe.dll
• System.Data.SqlServerCe.Entity.dll
• System.Net.Http.Formatting.dll
• System.Web.Helpers.dll
• System.Web.Http.dll
• System.Web.Http.WebHost.dll
• System.Web.Mvc.dll程序
• System.Web.Optimization.dll
• System.Web.Providers.dll
• System.Web.Razor.dll
• System.Web.WebPages.Deployment.dll
• System.Web.WebPages.dll
• System.Web.WebPages.Razor.dll
• WebActivatorEx.dll
• WebGrease.dll
• WebMatrix.Data.dll
• WebMatrix.WebData.dll

当我部署到干净的机器时,我收到以下错误消息:

无法找到请求的.Net Framework数据提供程序.它可能没有安装.

在我的开发机器上它工作正常.(我安装了sql ce)

我有什么问题吗？

Answer 1

我认为您真正想要做的是管理NuGet包,以便为EntityFramework添加SqlServerCompact支持.只需右键单击您的引用和Manager NuGet包.然后在对话框中搜索SqlServerCompact.你应该看到这个:

添加它应该添加上面答案中的等效字符串.我最终在web.config(或app.config,如果你正在做一个应用程序)中这样做了

    <entityFramework>
        <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlCeConnectionFactory, EntityFramework">
          <parameters>
            <parameter value="System.Data.SqlServerCe.4.0" />
          </parameters>
        </defaultConnectionFactory>
        <providers>
          <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
          <provider invariantName="System.Data.SqlServerCe.4.0" type="System.Data.Entity.SqlServerCompact.SqlCeProviderServices, EntityFramework.SqlServerCompact" />
        </providers>   
</entityFramework>   
<system.data>
        <DbProviderFactories>
          <remove invariant="System.Data.SqlServerCe.4.0" />
          <add name="Microsoft SQL Server Compact Data Provider 4.0" invariant="System.Data.SqlServerCe.4.0" description=".NET Framework Data Provider for Microsoft SQL Server Compact" type="System.Data.SqlServerCe.SqlCeProviderFactory, System.Data.SqlServerCe, Version=4.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />
        </DbProviderFactories>   
</system.data>

对不起,我迟到了一年,但希望这有助于其他人.

Answer 2

这是我正在使用的有效配置。

我添加了来自 NuGet 的项目：EntityFramework (6.0.1) EntityFramework.SqlServerCompact (6.0.1) Microsoft Sql Server Compact Edition (4.0.8876.1)。请注意，我没有将此程序集标记为复制本地。

我已添加 SQLCE 4 私人安装文件夹中的文件

然后我设置我的配置如下：

<configuration>
  <configSections>
    <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">

    </sectionGroup>
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
  </configSections>
