factory method pattern, which allows a class to defer instantiation to subclasses. [4] prototype pattern, which specifies the kind of object to create using a prototypical instance, and creates new objects by cloning this prototype. singleton pattern, which ensures that a class only has one instance, and provides a global point of access to it.

C# and Visual Basic are Microsoft's first languages made to program on the .NET Framework (later adding F# and more; others have also added languages). Though C# and Visual Basic are syntactically different, that is where the differences mostly end. Microsoft developed both of these languages to be part of the same .NET Framework development ...
extern - Specifies that a method signature without a body uses a DLL-import. override - Specifies that a method or property declaration is an override of a virtual member or an implementation of a member of an abstract class. readonly - Declares a field that can only be assigned values as part of the declaration or in a constructor in the same ...

In class-based programming, a factory is an abstraction of a constructor of a class, while in prototype-based programming a factory is an abstraction of a prototype object. A constructor is concrete in that it creates objects as instances of one class, and by a specified process (class instantiation), while a factory can create objects by instantiating various classes, or by using other ...
More than 4.4 million voters have cast early ballots in North Carolina, 4.2 million of them in person, according to the lab. The North Carolina Board of Elections said the number of early voters ...
The following shows the basic code of the object pool design pattern implemented using C#. For brevity the properties of the classes are declared using C# 3.0 automatically implemented property syntax. These could be replaced with full property definitions for earlier versions of the language.
In late July, Super Micro's auditor at the time, Ernst & Young (EY), raised concerns about the company's governance, transparency and internal control over financial reporting, prompting its board ...
