The object pool design pattern is used in several places in the standard classes of the .NET Framework. One example is the .NET Framework Data Provider for SQL Server.

Apps created with .NET Framework or .NET run in a software environment known as the Common Language Runtime (CLR), [1] an application virtual machine that provides services such as security, memory management, and exception handling. The framework includes a large class library called Framework Class Library (FCL).
The marker interface pattern is a design pattern in computer science, used with languages that provide run-time type information about objects.It provides a means to associate metadata with a class where the language does not have explicit support for such metadata.
The builder pattern is a design pattern that provides a flexible solution to various object creation problems in object-oriented programming.The builder pattern separates the construction of a complex object from its representation.
The Ruby on Rails framework has an API for OCC. [6] The Grails framework uses OCC in its default conventions. [7] The GT.M database engine uses OCC for managing transactions [8] (even single updates are treated as mini-transactions). Microsoft's Entity Framework (including Code-First) has built-in support for OCC based on a binary timestamp ...
