我试图在我的C控制台应用程序中使用Sqlite，但在尝试添加实体Framwork数据模型时，我收到以下消息：

<entityFramework>
  <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
  <providers>
    <provider invariantName="System.Data.SQLite" type="System.Data.SQLite.EF6.SQLiteProviderServices, System.Data.SQLite.EF6, Version=1.0.94.0, Culture=neutral, PublicKeyToken=db937bc2d44ff139" />

您的项目引用最新版本的实体框架；但是，无法为您的数据连接找到与此版本兼容的实体框架数据库提供程序。如果已安装兼容的提供程序，请确保在执行此操作之前已重新生成项目。否则，请退出向导，安装兼容的提供程序，并在执行此操作之前重新生成项目

<entityFramework>
  <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
  <providers>
    <provider invariantName="System.Data.SQLite" type="System.Data.SQLite.EF6.SQLiteProviderServices, System.Data.SQLite.EF6, Version=1.0.94.0, Culture=neutral, PublicKeyToken=db937bc2d44ff139" />

  </providers>
</entityFramework>
<connectionStrings>
  <add name="SettingContext" connectionString="Data Source=setting.db" providerName="System.Data.SQLite" />
复制步骤：

<entityFramework>
  <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
  <providers>
    <provider invariantName="System.Data.SQLite" type="System.Data.SQLite.EF6.SQLiteProviderServices, System.Data.SQLite.EF6, Version=1.0.94.0, Culture=neutral, PublicKeyToken=db937bc2d44ff139" />
    <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
    <!--<provider invariantName="System.Data.SQLite.EF6" type="System.Data.SQLite.EF6.SQLiteProviderServices, System.Data.SQLite.EF6" />-->
  </providers>
</entityFramework>
<connectionStrings>
  <add name="SettingContext" connectionString="Data Source=setting.db" providerName="System.Data.SQLite" />
添加新的.NET4控制台应用程序 安装System.DataBase.SQLite x86/x64 Nuget软件包，该软件包将自动将实体Framwork软件包作为依赖项安装 使用“添加新项”对话框添加ADO.NET实体数据模型 完成上述步骤后，创建了以下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 -->

  </configSections>
  <system.data>
    <!--
        NOTE: The extra "remove" element below is to prevent the design-time
              support components within EF6 from selecting the legacy ADO.NET
              provider for SQLite (i.e. the one without any EF6 support).  It
              appears to only consider the first ADO.NET provider in the list
              within the resulting "app.config" or "web.config" file.

    <DbProviderFactories>
      <add name="SQLite Data Provider" invariant="System.Data.SQLite" description=".NET Framework Data Provider for SQLite" type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite" />

    </providers>
  </entityFramework>
</configuration>

<entityFramework>
  <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />

<connectionStrings>
  <add name="SettingContext" connectionString="Data Source=setting.db" providerName="System.Data.SQLite" />
您只需要以下软件包：

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="EntityFramework" version="6.1.1" targetFramework="net40" />
  <package id="System.Data.SQLite.Core" version="1.0.94.0" targetFramework="net40" />
  <package id="System.Data.SQLite.EF6" version="1.0.94.0" targetFramework="net40" />
</packages>

<entityFramework>
  <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
  <providers>
    <provider invariantName="System.Data.SQLite" type="System.Data.SQLite.EF6.SQLiteProviderServices, System.Data.SQLite.EF6, Version=1.0.94.0, Culture=neutral, PublicKeyToken=db937bc2d44ff139" />
    <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
    <!--<provider invariantName="System.Data.SQLite.EF6" type="System.Data.SQLite.EF6.SQLiteProviderServices, System.Data.SQLite.EF6" />-->
  </providers>
</entityFramework>
<connectionStrings>
  <add name="SettingContext" connectionString="Data Source=setting.db" providerName="System.Data.SQLite" />
然后将构建配置设置为x86

<entityFramework>
  <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
  <providers>
    <provider invariantName="System.Data.SQLite" type="System.Data.SQLite.EF6.SQLiteProviderServices, System.Data.SQLite.EF6, Version=1.0.94.0, Culture=neutral, PublicKeyToken=db937bc2d44ff139" />
    <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
    <!--<provider invariantName="System.Data.SQLite.EF6" type="System.Data.SQLite.EF6.SQLiteProviderServices, System.Data.SQLite.EF6" />-->
  </providers>
</entityFramework>
<connectionStrings>
  <add name="SettingContext" connectionString="Data Source=setting.db" providerName="System.Data.SQLite" />


<entityFramework>
  <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
  <providers>
    <provider invariantName="System.Data.SQLite" type="System.Data.SQLite.EF6.SQLiteProviderServices, System.Data.SQLite.EF6, Version=1.0.94.0, Culture=neutral, PublicKeyToken=db937bc2d44ff139" />

    <!--<provider invariantName="System.Data.SQLite.EF6" type="System.Data.SQLite.EF6.SQLiteProviderServices, System.Data.SQLite.EF6" />-->
  </providers>
</entityFramework>
<connectionStrings>
  <add name="SettingContext" connectionString="Data Source=setting.db" providerName="System.Data.SQLite" />
您所做的只是支持代码优先开发。您还需要安装SQLIte VS工具，从system.data.SQLIte.orgI下载。我正在寻找合适的下载，但找不到。您能指出与2013.NET 4.0相比的正确方向吗？下载的名称是sqlite-netFx451-setup-bundle-x86-2013-1.0.94.0.exe。我看到这些软件包是针对net45的。它们是否也适用于net40项目？刚刚更新了我的回复
