mvc数据表机构修改引起运行错误的解决方法



错误提示：

The model backing the 'xyzContext' context has changed since the database was created. Either manually delete/update the database, or call Database.SetInitializer with an IDatabaseInitializer instance. For example, the RecreateDatabaseIfModelChanges strategy will automatically delete and recreate the database, and optionally seed it with new data.

解决办法：

This is a bug in CTP4 for using EF with pre-existing databases.

You can fix it by calling:

Database.SetInitializer<YourContext>(null);

in the Application_Start method of Global.asa
