Adding a static constructor is easy for example: [Serializable] public abstract class CustomBase<T> : BusinessBase<T> where T : CustomBase<T> { static CustomBase() { } } All static fields are initialized before the static constructor executes, so adding this bit of code ensures that the static fields in this class will be initialized before an instance of this class, or a subclass, can be created. The downside to this is a performance impact. When you declare a static constructor in a class, the compiler injects code everywhere any method of this class is accessed, checking to ensure that the static constructor has been run before any other code. Obviously, all this extra checking can have a negative impact on performance. It is actually slightly worse than this, because the compiler also injects code to ensure that the static constructor is only called exactly once, even in a multithreaded environment. So the code it injects is relatively complex and involves potential locking.

during the design phase as all the people involved in the design process thrash out which objects are real, which are duplicates, and which should be just data fields. This is healthy and important, though obviously some judgment must be exercised to avoid analysis paralysis, whereby the design stalls entirely due to the debate. Let s discuss this in a bit more detail.

The CREATE TABLE statement returned from DBMS_METADATA included the following: LOB ("TXT") STORE AS BASICFILE ( TABLESPACE "USERS"

The RemoveChild() method will be important later in the chapter during the implementation of BusinessBase and BusinessListBase, and specifically for the implementation of the System. ComponentModel.IEditableObject interface. This interface has some tricky requirements for interaction between a child object in a collection and the collection itself.
