Microsoft®.NET platform includes very broad, generic functionality – This makes the platform suitable for a wide variety of application types and architectures – However, specific customer segments have common needs at a higher level of abstraction. The platform does not always directly support these without a lot of manual work – Prescriptive guidance that links functionality together is lacking

How many times do enterprise developers ask: – Most applications need something like this – People must have written hundreds of things like this – I wish I could find a solution for this that I could reuse – …

10. ©2004 Avanade Inc. All rights reserved. The Avanade name and logo are registered trademarks in the US and other countries. Application Block Feedback In general feedback has been extremely positive, but there is room for improvement: – Make blocks consistent – Make blocks work well together – Minimize dependencies −On other blocks −On infrastructure – Make evaluation and understanding of blocks easier – Make using blocks easier – Make it easier to configure blocks

12. ©2004 Avanade Inc. All rights reserved. The Avanade name and logo are registered trademarks in the US and other countries. Introducing “Enterprise Library”! Library of reusable software assets to address common enterprise development challenges, consistently, correctly and quickly Part of the patterns & practices guidance library Strong focus on consistency, extensibility, ease of use and integration v1 produced in partnership with Avanade, leveraging experience from customer engagements and incorporating aspects of the ACA.NET application framework

13. ©2004 Avanade Inc. All rights reserved. The Avanade name and logo are registered trademarks in the US and other countries. Enterprise Library Ecosystem Enterprise Library is a solid core to be leveraged and extended by others Avanade has built a new version of ACA.NET using Enterprise Library as the foundation Enterprise Library Partner Program will encourage other partners to contribute to EntLib and build their own offerings on top Microsoft will foster a community of customers and partners using, discussing and extending the library

Integration Packaged as integrated library Blocks are designed to work well together, but they can still be used individually – Dependencies are encapsulated into pluggable providers Configuration understands how to use blocks together in application – Blocks used as providers for other blocks

21. ©2004 Avanade Inc. All rights reserved. The Avanade name and logo are registered trademarks in the US and other countries. Configuration Application Block Allows applications to easily read and write configuration data from configurable storage locations Used by all blocks in Enterprise Library, can also be used by customer blocks, frameworks and applications Includes two parts: – Configuration Runtime, which applications use at runtime to access configuration data – Configuration Designtime, which provides nodes that are used by the configuration tool to give a simple design-time experience Configuration can be encrypted and individual elements can be masked in the tool Enterprise Library will include standalone and Visual Studio- integrated versions of the configuration tool

22. ©2004 Avanade Inc. All rights reserved. The Avanade name and logo are registered trademarks in the US and other countries. Data Access Application Block Provides simplified access to the most common data access operations Aim was to keep much of the simplicity of the original DAAB blocks, but to provide additional features requested by customers Notable new features: – Support for multiple database types through a factory (Microsoft ® SQL Server™, Oracle and DB2 out of the box). This provides consistent and portable code (caveats apply!) – Connection strings are stored and managed in external configuration

25. ©2004 Avanade Inc. All rights reserved. The Avanade name and logo are registered trademarks in the US and other countries. Caching Application Block Provides a flexible and extensible caching mechanism that can be used at all layers of an application Supports backing stores that persist cache data into a database or isolated storage, so the data can survive app restarts Can be used in Microsoft ® ASP.NET apps, although the ASP.NET cache is preferred for simple scenarios Supports similar scenarios to the original caching block, but with a revised architecture to make it more thread- and exception-safe

27. ©2004 Avanade Inc. All rights reserved. The Avanade name and logo are registered trademarks in the US and other countries. Security Application Block Provides a simple API and pluggable implementations of core security primitive operations Covers five security areas: Authentication, Authorization, Roles, Profile and Security Caching Each module supports extensible plug-in providers. In general we supply plug-ins for common Microsoft infrastructure (Active Directory ®, AzMan) as well as a light-weight database implementation Developers can build their own plug-ins to interface with existing security solutions

29. ©2004 Avanade Inc. All rights reserved. The Avanade name and logo are registered trademarks in the US and other countries. Cryptography Application Block Provides a simplified approach to implementing common cryptography scenarios Includes modules for symmetric cryptography and hashing Each module supports pluggable algorithms and key stores – Supports all.NET crypto algorithms out of the box, or developers can implement their own Algorithms and keys can be managed through the configuration tool

30. ©2004 Avanade Inc. All rights reserved. The Avanade name and logo are registered trademarks in the US and other countries. Exception Handling Application Block Facilitates consistent exception handling behavior at logical boundaries of an application Allows the creation of “exception policies” which dictate which actions should be taken for specific exception types at the logical boundary – Example: All security exceptions arising from the business layer need to be logged, and the messages sanitized before being propagated to the caller Actions are extensible; we provide Logging, Wrapping one exception with another, and Replacing one exception with an other Block has little in common with the existing EMAB which was primarily used to log exceptions

32. ©2004 Avanade Inc. All rights reserved. The Avanade name and logo are registered trademarks in the US and other countries. Logging and Instrumentation Application Block Allows applications to log business and operations data to various destinations, which are externally configurable Replaces the Enterprise Instrumentation Framework and the existing Logging Application Block Configuration specifies which messages go where, and how they are formatted Formatters and sinks are extensible. We provide sinks for Event Log, Database, Text File, MSMQ, E- mail, WMI and Windows Event Tracing

Upgrading existing applications Enterprise Library is not compatible with previous Application Blocks or ACA.NET Migration guidelines in the documentation Recommended approach: used a phased adoption, using Enterprise Library for new applications and significant redevelopment Multiple application blocks and frameworks may coexist within an environment (e.g.. UIP) *This is a slide from the Microsoft Patterns and Practices Team

39. ©2004 Avanade Inc. All rights reserved. The Avanade name and logo are registered trademarks in the US and other countries. What’s next? Microsoft will continue to enhance Enterprise Library, providing new Application Blocks to assist with scenarios such as Validation, SOA and Smart Client Microsoft is planning a Microsoft®.NET 2.0 “Whidbey” compliant release around the time that.NET 2.0 and Microsoft® Visual Studio® 2005 are released Get involved in the community to participate in requirements, reviews and beta testing! http://workspaces.gotdotnet.com/entlib http://workspaces.gotdotnet.com/entlib *This is a slide from the Microsoft Patterns and Practices Team
