i want to add my model classes by ((C# Code-DOM)) and of course i did. but now i have problem with creating DbSet properties inside my Context class ...

Answer 1

yes i did!..
this: https://romiller.com/2012/03/26/dynamically-building-a-model-with-code-first/
And this: Create Table, Run Time using entity framework Code-First
are solution. no need to dispute with dbSets directly. it just works by do some thing like that:
public class MyDBContext : DbContext
{
public MyDBContext() : base("MyCon")
{
Database.SetInitializer<MyDBContext>(new CreateDatabaseIfNotExists<MyDBContext>());
}
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
var entityMethod = typeof(DbModelBuilder).GetMethod("Entity");
var theList = Assembly.GetExecutingAssembly().GetTypes()
.Where(t => t.Namespace == "FullDynamicWepApp.Data.Domins")
.ToList();
foreach (var item in theList)
{
entityMethod.MakeGenericMethod(item)
.Invoke(modelBuilder, new object[] { });
}
base.OnModelCreating(modelBuilder);
}
}

For those using EF Core that stubble here:
The code below is only for one table with the generic type. If you want more types you can always pass them through the constructor and run a cycle.
public class TableContextGeneric<T> : DbContext where T : class
{
private readonly string _connectionString;
//public virtual DbSet<T> table { get; set; }
public TableContextGeneric(string connectionString)
{
_connectionString = connectionString;
}
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
var entityMethod = typeof(ModelBuilder).GetMethods().First(e => e.Name == "Entity");
//the cycle will be run here
entityMethod?.MakeGenericMethod(typeof(T))
.Invoke(modelBuilder, new object[] { });
base.OnModelCreating(modelBuilder);
}
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
optionsBuilder.UseSqlServer(_connectionString); // can be anyone
}
}
