执行EF操作时遇到
No connection string named ‘TestEntities‘ could be found in the application config file错误

解决：
需要在应用程序的App.config中增加配置

1  <connectionStrings>
2  <add name="TestEntities" 
3 　　　　　connectionString="metadata=res://*/TestData.csdl|res://*/TestData.ssdl|res://*/TestData.msl;
4  　　　　　　provider=MySql.Data.MySqlClient;provider connection string=&quot;
5 　　　　 　　server=localhost;user id=root;
6  　　　　　　password=admin;persistsecurityinfo=True;database=test&quot;"
7 　　　　　providerName="System.Data.EntityClient" />
8  </connectionStrings>
