Entity Framework 7 Connection string

Question

This is how i made connection to database in EF6: 

Form1.context = new PostgresContext(new NpgsqlConnection(Configuration.connectionString));

How Can i do it in EF 7? Pass Connection object or connection string to dbcontext?

Hello,

Since this is a EF question I am moving your question to the EF forum.

Hi aivarinns,

>>How Can i do it in EF 7? Pass Connection object or connection string to dbcontext?

As far as I know, EF7 doesn't support Connection object and connection string with Dbcontext Constructor. you could use DbContextOptions or ServiceProvider to connect your database.

#DbContextOptions

public class BloggingContext : DbContext
{
    public BloggingContext(DbContextOptions options)
        : base(options)
    { }

    public DbSet<Blog> Blogs { get; set; }
}

#ServiceProvider

using (var context = serviceProvider.GetService<BloggingContext>())
{
  // do stuff
}

For more information about Configuring a DbContext, please refer to:
