We have an MVC5 application which connects to azure database, after deploying in azure app service which has a custom domain name configured we get an error as 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.
When I deply to an azure app service without custom domain name it works fine.
Connection string in the application has metadata.
