EF core with .net core 3.1

Steps to use EF Core in project.  (easy)

>> Go to Nuget packages and install "Microsoft.EntityFramework.SqlServer". This will install few more dependent packages with it. 

>> Right click and create a folder named "Database"

>> Add a class and named it AppDbContext.cs (it could be any name)

>> Inherit the above class with "DbContext" class. "DbContext" class is available  when we use 'using Microsoft.EntityFrameworkCore;' on top of a class file. 

>> Create entities (tables) classes in model folder (or in same folder)

>> Create DB set property for above model class in AppDbContext class.

    public class AppDBContext: DbContext

    {

        public AppDBContext(DbContextOptions<AppDBContext> options) : base(options)

        {

        }

        public DbSet<Student> Students { get; set; }

    }

>> Now register the DBContext class in startup.ConfigureService method.

  public void ConfigureServices(IServiceCollection services)

        {

            services.AddDbContext<AppDBContext>(options =>

               options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));

        }
