Sqlite数据库 找不到请求的 .Net Framework Data Provider。可能没有安装

 

解决方法 在web.config里面添加

<system.data>
        <DbProviderFactories>
            <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, Version=1.0.66.0, Culture=neutral, PublicKeyToken=db937bc2d44ff139" />
        </DbProviderFactories>
    </system.data>

注意:Version后面的 1.0.66.0  要根据你安装的sqlite的版本来写.

 

所有的web.config如下 

<?xml version="1.0" encoding="utf-8"?>
