La última versión de la Enterprise Library del grupo de Patterns and Practices de Microsoft se libero en mayo del 2007 y es compatible con .Net 2.0 y 3.0.
Información actualizada y material didactico se puede localizar en el sitio comunitario de la libreria empresarial.
Enterprise Library: La evolución de los .NET Application Blocks de patterns & practices
Entlib – Enterprise Library es la evolución de los Bloques Aplicativos .NET que han sido desarrollados por el Grupo PAG (Microsoft Platform Architecture Guidance) dentro de Microsoft. Este grupo genera guías y arquitecturas de referencia, patrones de diseño, y código fuente desarrollado con la implementación de diversos escenarios tecnológicos.
Los desarrolladores en su momento puden usar la guía para comprender las mejores prácticas referenciadas y sugeridas por Microsoft para aplicaciones .NET; o incorporar el bloque aplicativo como tal dentro de sus desarrollos, en su formato original y/o extendido.
Los “Bloques Aplicativos .NET” que en su momento fueron liberados son los siguientes:
- Authorization and Profile Application Block
- Caching Application Block for .NET
- Configuration Management Application Block for .NET
- Data Access Application Block for .NET
- Exception Management Application Block for .NET
- Logging Application Block
- Smart Client Offline Application Block
- Updater Application Block for .NET
- User Interface Process Application Block – Version 2.0
- User Interface Process Application Block for .NET
- Web Service Façade for Legacy Applications
Por la forma gradual en que fueron desarrollados dichos bloques aplicativos, los mismos estaban desintegrados y la experiencia de utilización e extensibilidad eran diferentes entre si. Además que la utilización de cada uno de dichas piezas de software obligaba a la instalación de componentes de software independientes.
Con estas áreas de oportunidad la nueva versión de los “.NET Application Blocks” se integró con la nueva etiqueta de Enterprise Library. El grupo de PAG ha anunciado lo siguiente:
Entlib es una librería de activos de software reutilizable que atenderá los retos comunes en el desarrollo del software empresarial.
Entlib está focalizado en la consistencia, extensibilidad, fácil utilización e integración de los diversos bloques aplicativos existentes y futuros.
Es importante aclarar que Enterprise Libray no es un producto como tal, sino que es un componente de software que es proporcionado como está, pero del cual se puede contratar soporte directamente de Microsoft, tratado bajo un esquema parecido al código escrito por los usuarios.

- Guidance Automation Extensions and Guidance Automation Toolkit
Requerimientos:
- Sistema oprativo: Windows Server 2003; Windows Vista; Windows XP
Note: If you already have the Enterprise Library 3.0 installed, you must uninstall it before installing the Enterprise Library 3.1. However, you can install the Enterprise Library 3.0 or the Enterprise Library 3.1 when 2.0 is already installed.
- Microsoft .NET Framework 2.0 or 3.0. You need .NET Framework 3.0 for the
Application Block Software Factory and the WCF adapters for the Validation
Application Block and Exception Handling Application Block - Microsoft Visual Studio 2005 development system (any of the following
editions):- Microsoft Visual Studio 2005 Standard Edition
- Microsoft Visual Studio 2005 Professional Edition
- Microsoft Visual Studio 2005 Team Edition for Software Developers
- Microsoft Visual Studio 2005 Team Edition for Software Testers
- Microsoft Visual Studio 2005 Team Edition for Software Architects
- Microsoft Visual Studio 2005 Team Suite
- To use the Application Block Software Factory and the Strong-Naming
Guidance Package, you need the Guidance Automation Extensions (GAX). To
modify these guidance packages, you also need the Guidance Automation
Toolkit (GAT). - Some blocks and samples require the use of Microsoft SQL Server or other
database products. - Visual Studio Team System or NUnit 2.2 is required if you want to
execute unit tests.

More Information
|
Enterprise Library The patterns & practices Enterprise Library is a library of reusable and extensible application blocks designed to assist developers with common enterprise development challenges. Enterprise Library 3.0 contains application blocks for Caching, Cryptography, Data Access, Exception Handling, Logging, Policy Injection, Security and Validation. |
|
|
Caching Application Block The Caching Application Block is a component of Enterprise Library which provides a flexible and extensible caching mechanism for use in client and server-side .NET development projects. |
|
|
Smart Client – Composite UI Application Block Are you building applications with complex user interfaces? Do you want to take full advantage of the power of the Microsoft Windows desktop? Check out this recently released application block that provides guidance on building world-class, enterprise ready, client applications. Available both in C# and Visual Basic .NET. |
|
|
Cryptography Application Block The Cryptography Application Block is a component of Enterprise Library which makes it easier to include cryptographic functionality in .NET applications. The block provides a simple interface to DPAPI, symmetric encryption and hashing, and uses the Enterprise Library configuration tool to simplify key management. |
|
|
Data Access Application Block The Data Access Application Block is a component of Enterprise Library which reduces the amount of custom code that you need to create, test, and maintain when building data access layers in .NET applications. |
|
|
Exception Handling Application Block The Exception Handling Application Block is a component of Enterprise Library that makes it easier to implement consistent exception handling policies at logical tiers in an application. Exception policies can be configured to perform tasks such as logging exceptions, wrapping or replacing exception types. |
|
|
Logging Application Block The Logging Application Block is a component of Enterprise Library that allows developers to instrument their applications with logging and tracing calls. Log and trace messages can be filtered, formatted and routed to a choice of trace listeners, including the event log, text files, database or WMI. |
|
|
Policy Injection Application Block The Policy Injection Application Block is a component of Enterprise Library which allows developers to specify the crosscutting behavior of objects in terms of a set of policies. Crosscutting concerns are the necessary tasks, features, or processes that are common across different objects. Examples are logging, authorization, validation, and instrumentation. |
|
|
Security Application Block The Security Application Block is a component of Enterprise Library that builds on the capabilities of the Microsoft .NET Framework to help you perform authentication, authorization, check role membership and access profile information. |
|
|
Validation Application Block The Validation Application Block is a component of Enterprise Library which provides a common approach to defining validation rules for your business objects that allows them to be reused across different layers of your application. |

Web Service Facade for Legacy Applications This guide discusses best practices for interfacing with legacy applications by using Microsoft® ASP.NET Web services and the Microsoft .NET Framework. The .NET Framework provides the foundation for creating a Legacy Application Interface solution using Microsoft technologies. This guide provides a sample solution using a Microsoft FoxPro® database as the legacy application and connecting it to a .NET-based application using ASP.NET Web services and SOAP. The specific technologies involved are ASP.NET, C# or the Microsoft Visual Basic® .NET development system, the .NET Framework, XML, Visual Basic, COM, and ADO. |
