WPF EF连接Sqlite注意事项

1. APp.config 配置，否者在导入数据源时无法找到Sqlite引擎

<?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" />

  </connectionStrings>

    </providers>

  </entityFramework>
  <userSettings>
    <DXThemeManager>
      <setting name="ApplicationThemeName" serializeAs="String">
        <value></value>
      </setting>
    </DXThemeManager>
  </userSettings>
  <system.data>
    <DbProviderFactories>
      <remove invariant="System.Data.SQLite.EF6" />
      <add name="SQLite Data Provider (Entity Framework 6)" invariant="System.Data.SQLite.EF6" description=".NET Framework Data Provider for SQLite (Entity Framework 6)" type="System.Data.SQLite.EF6.SQLiteProviderFactory, System.Data.SQLite.EF6" />
    <remove invariant="System.Data.SQLite" /><add name="SQLite Data Provider" invariant="System.Data.SQLite" description=".NET Framework Data Provider for SQLite" type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite" /></DbProviderFactories>
  </system.data>
</configuration>

2、数据库相对路径

data source=|DataDirectory|\AppData\LifeEvaluation.db"

3、加载Sqlitedll后编译错误，使用.net4.5.2环境，并且使用NuGget获取 Sqlite 的 1.0.502 版本包，并且安装
