【问题描述】:
我想将 SQLite 与 Entity Framework 和 Visual Studio 2013 Desktop Express 一起使用。
为此,我右键单击参考并安装(带有选定的依赖项)“System.Data.SQLite(X86/x64)”(版本 1.0.94.1)NuGet 包
现在,如果我向我的项目添加一个新元素并选择 ADO.NET 实体数据模型,我看不到 SQLite 提供程序:我只有 Microsoft SQL Server。
我有 .NET Framework 4.5.1 和 Windows 7。
这是我的 App.config
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</configSections>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
<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" />

</system.data>
