repository-pattern

In keeping with the Repository pattern of data input, I've a question in regards to using inherited classes. For instance, suppose I would have the class...

class Employee

IEmployeeRepository
{
 Add(Employee employee);
}

This works fine, nothing wrong with it so far... but now let's say I continue on..

class Manager : Employee

Okay, now let's assume that I never need to enter a manager different than an Employee? What's the best approach here? Would a scenario such as ..

IEmployeeRepository
{
 Add<T>(T employee) where T : Employee
}

Be the best approach, or do I need to abstract a different repository for each type?

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More

Difference between the Repository Pattern and the View Model Pattern

as seen on Stack Overflow - Search for 'Stack Overflow'
I am trying to create a site using the ASP MVC Framework. Some of the documentation use the IRepository pattern to abstract the information being sent to the view for rendering, while others recommend using a ViewModel (as in MVVC). What is the difference? Aren't these the same concept? Thanks… >>> More
