Abstract Factory: System.Data.Common.DbProviderFactory. Every member function of this class is a factory method.
Builder: The WCF channel construction infrastructure.
Factory Method:
System.Data.IDbConnection.BeginTransaction(). The type of transaction created depends on the underlying IDbConnection implementation.
WebRequest.Create() returns a concrete type that depends on the URL scheme.
Prototype - used in framework for cloning and serialization
Singleton - used as an activation method in WCF, i.e. a web service may be treated as a singleton by the WCF infrastructure. Ditto for .NET Remoting.
Structural patterns
Adapter: The ADO.NET providers, eg System.Data.SqlClient.SqlConnection, System.Data.OleDb.OleDbConnection etc. Each provider is an adapter for its specific database.
Composite: many examples
System.Windows.Forms.Control and its derived classes.
System.Web.UI.Control and its derived classes.
System.Xml.XmlNode and its derived classes.
Decorator:
System.Windows.Controls.Decorator (in WPF).
Some implementations of Stream are decorators around an inner stream (e.g. GZipStream, CryptoStream).
Facade: System.Xml.Serialization.XmlSerializer. XmlSerializer hides a complex task (that includes generating assemblies on the fly!) behind a very easy-to-use class.
Proxy: The web service proxies generated by svcutil.exe and deriving from System.ServiceModel.ClientBase<TChannel>
Behavioral Patterns
Chain of responsibility: System.Web.UI.Control.OnBubbleEvent() and System.Web.UI.Control.RaiseBubbleEvent().
Command:System.Windows.Input.ICommand (in WPF).
Interpreter: System.Linq.Expressions.Expression and related classes.
Iterator: many examples
System.Collections.IEnumerable.
System.Collections.Generic.IEnumerable<T>.
System.Data.IDataReader.
Memento: The .NET Serializable pattern is a variation on the Memento pattern.
Observer - The .NET event mechanism.
Strategy - Sort method in ArrayList
Template Method - Render method for custom controls
Visitor : System.Linq.Expressions.ExpressionVisitor
Но тут ничего не говорится по паттерн Bridge.
Есть идеи где применяется Мост в .NET?
