سلام

من سایتی رو با mvc و sql 2014 نوشتم و آپلود کردم توی کنترل پنل plesk و از این آموزش استفاده کردم.

The  context is being used in Code First mode with code that was generated  from an EDMX file for either Database First or Model First development.   This will not work correctly. To fix this problem do not remove the  line of code that throws this exception. If you wish to use Database  First or Model First, then make sure that the Entity Framework  connection string is included in the app.config or web.config of the  start-up project. If you are creating your own DbConnection, then make  sure that it is an EntityConnection and not some other type of  DbConnection, and that you pass it to one of the base DbContext  constructors that take a DbConnection. To learn more about Code First,  Database First, and Model First see the Entity Framework documentation  here: http://go.microsoft.com/fwlink/?LinkId=394715


دلیلش به کانکشن استرینگ مربوطه یا چیز دیگه؟
