Follow all the easy steps for move your LocalDB table to SQL server db Table.
1. Inspect the Web.config File Connection String and Connect to Local Database
Change the defaut connection string:
<add name="DefaultConnection" connectionString="Data Source=(LocalDb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\aspnet-WebApp-20190226025646.mdf;Initial Catalog=aspnet-WebApp-20190226025646;Integrated Security=True" providerName="System.Data.SqlClient" />
To your connection string:
<add name="DefaultConnection" connectionString="Data Source=PC-YWGSB;Initial Catalog=WebApp;user id=admin;password=admin" providerName="System.Data.SqlClient" />
2. Then use the commands for DB Migration "Codefirst"
This is the official guide:
https://learn.microsoft.com/it-it/aspnet/mvc/overview/getting-started/getting-started-with-ef-using-mvc/migrations-and-deployment-with-the-entity-framework-in-an-asp-net-mvc-application
From the Tools menu, select NuGet Package Manager > Package Manager Console.
At the PM> prompt enter the following commands:
- enable-migrations
- add-migration InitialCreate
- update-database
The database will be created automatically during migration.
If you already have one make sure to backup all tables.
