How to add new tables to NOPCommerce

I spent plenty of time for delving into this problem' depths. I can summarize the solution as follows:

1. Create The Entity Class (e.g Entity.cs)

Path : Nop/Core/Domain/Entity.cs

2. Create The Mapping Class (e.g EntityMap.cs)

Path : Nop/Data/Mapping/EntityMap.cs

3. Create a Model for MVC (e.g EntityModel.cs)

Path : Nop/Admin/Models/EntityModel.cs OR Nop/Web/Models/EntityModel.cs

4. Create a validator for model (e.g EntityValidator.cs)

Path : Nop/Admin/Validators/EntityValidator.cs OR Nop/Web/Validators/EntityValidator.cs

5. Create A Mapping Configuration On AutoMapperStartupTask.cs for Entity and Model

Path : Nop/Admin/Infrastructure OR Nop/Web/Infrastructure

6. Apply Mapping between Model and Entity on MappingExtensions.cs

Path : Nop/Admin OR Nop/Web

7. Create a service class and service interface (e.g EntityService.cs , IEntityService.cs)

Path : Nop/Services/EntityService.cs AND Nop/Services/IEntityService.cs

8. Update DependencyRegistrar.cs

9. Finally Create Controller and View for given model

Cannot implicitly convert type 'int?' to 'int'. An explicit conversion exists (are you missing a cast?)

I got this when i use linq query
query is below
public IQueryable<GasUtilGas> LoadAllForkliftGasUtilByDetailId(int id)
        {
            var res = from gu in db.tblForlkliftGasUtils
                      join g in db.tblGas on gu.GasID equals g.GasID
                      select new GasUtilGas { GasNo = g.GasNumber};
            return res;
        }

It seems like g.GasNumber is a nullable int field in the database.  Change the model to this:
public class GasUtilGas
    {
        public int? GasNo { get; set; }   
    }

The data source does not support server-side data paging

You can't use an IQueryable object to data bind to a GridView and still use Paging and Sorting. You must return a List to the GridView using the ToList() method. Thanks
