I found the solution : https://github.com/aspnet/EntityFramework/wiki/Configuring-a-DbContext#config-from-external-code

Context Code

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

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

Application code

var optionsBuilder = new DbContextOptionsBuilder();
optionsBuilder.UseSqlServer(@"Server=.\SQLEXPRESS;Database=Blogging;integrated security=True;");
var context = new BloggingContext(optionsBuilder.Options);

Thank you
