在使用SQLite时需要添加一个引用 System.Data.SQLite,C#在运行时候会提示混合模式程序集是针对“v2.0.50727”版的运行时生成的,在没有配置其他信息的情况下,无法在 4.0 运行时中加载该程序集 ,这个问题可以在app.config中添加一个配置节:startup
<startup uselegacyv2runtimeactivationpolicy="<span">"<span>true</span><span>"</span>> <supportedruntime version="<span">"<span>v4.0</span><span>"</span>/> </supportedruntime></startup>
