An abstract class cannot be instantiated. An abstract class not only contains abstract methods and assessors but also contains non-abstract methods, properties, and indexers. It is not possible to modify an abstract class with the sealed modifier because the two modifiers have opposite meanings.

Why do you implement a property in a class as opposed to a field?

Properties provide a level of abstraction allowing you to change the fields while not affecting the external way they are accessed by the things that use your class. @Kent points out that Properties are not required to encapsulate fields, they could do a calculation on other fields, or serve other purposes.

The properties of a field describe the characteristics and behavior of data added to that field. A field’s data type is the most important property because it determines what kind of data the field can store.

How to safely implement the propertychanged interface in C #?

The interface has just one member, PropertyChanged, which is an event that consumers can subscribe to. The version that Richard posted is not safe. Here is how to safely implement this interface: Makes a copy of the PropertyChanged delegate before attempting to invoke it (failing to do this will create a race condition).
