Repository in T4 template

Question

I am writing a T4 template for repositories.

Say we have Customers/Orders/Products tables. We then have CustomerRepo, OrdersRepo, and ProductsRepo.

Is it a good practice to have a generic repo for all of them?

public partial class Repository

{

private IContext context;
public Repository()
{
    _Product = new ProductRepo();
    _Customer = new CustomerRepo();
}

public Repository(IContext context)
{
    this.context = context;
    _Product = new ProductRepo(context);
    _Customer = new CustomerRepo(context);
}

private ProductRepo _Product;
public ProductRepo Product {
    get { return _Product; }
}
// Product

private CustomerRepo _Customer;
public CustomerRepo Customer {
    get { return _Customer; }
}
// Customer

}

Answer 1

I find that it is best to make a repository for each type rather than one single repository. Otherwise the repository tends to get large as all sorts of functionality is added.

You can even look at implementing your repository like this post. You can even extend the concept and implement generic and have IRepository<T> where T:IEntity and then have a base implementation called BaseRepository<T>. Based on your additions to the question you might want to use Factory Pattern or Facade Pattern or Dependency Injection (using Unity/StructureMap container). It depends on how complex it is and how flexible your solution needs to be.
