Can't open database in MVC project Visual studio 2015

Question

I have an MVC project. When I added database I couldn't open it or create new tables. (I added it with right click on "App_Data" -> Add new Item -> SQL Server DB)

Right click on my DB and there is no option for creating tables or something

When I open DB with double click there are strange symbols

In Server Explorer my DB is absent

How can I work with my DB?

Answer 1

Open the .mdf file from Data Connections section in the Server Explorer, Right click on 'Data Connections' section on the Server Explorer and select 'Add Connection...' and select 'Microsoft SQL Server Database File' and browse your solution .mdf file.
