I have database define in App_Data folder. Is it possible to deploy my app with database included App_Data if folder? Or update azure db automatically? Or if it isn't possible what's the best way to update azure db manually?
first solution for you
if you work with the entity framework, you can do the direct update, in the first step you have to replace the DB connection string in Web.config:
<add name="DefaultConnection" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=OnlineAuctionDb;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\OnlineAuctionDb.mdf" providerName="System.Data.SqlClient"/>
by connection string of database in azure
<add name="DefaultConnection" connectionString="Data Source=xxxxxxx.database.windows.net,1433;Initial Catalog=database;User Id=user@xxxxxxxx.database.windows.net;Password=mypassword" providerName="System.Data.SqlClient"/>
after if you publish check this value "selected Run the code First Migrations" as you see in this picture
In the last step, you click on the Publish button
Second solution for you
you should get the SQL script from your local database and run it on your remote database . (don't forgot to change connection string in your web.config for test before publish )
