.Net 4.0 Features - A walk through

Introduction

This article discuss on the application server technologies are coming in Windows Server and .NET Framework 4.0.

Windows Communication Foundation 4.0

• Representational state transfer (REST) enhancements
  · Simplified building of RESTful services
  · Templates to accelerate building Singleton & Collection Services, Atom Feed and Publishing Protocol Services, and HTTP Plain XML Services

• Messaging enhancements

             .Protocols: WS-Discovery, WS-I BP 1.2
             · Duplex durable messaging

• Correlation enhancements

             · Content- and context-driven, one-way support

• Declarative workflow services

            · Seamless integration between Windows Workflow Foundation and Windows Communication Foundation and unified Extensible Application Markup Language (XAML) model
            · Ability to build an entire application in XAML, from presentation to data to services to workflow

Windows Workflow Foundation 4.0

• Significant improvements in performance and scalability

             · Performance gains in all aspects of Windows Workflow Foundation at design time and runtime
             · At least a tenfold improvement in performance
             · Improvements in serialization performance and size needs

• New workflow flow-control models and prebuilt activities

             · New flowchart control model
             · Expanded built-in activities: Windows PowerShell, database, messaging, etc.

• Enhancements in workflow modeling

            · Persistence control, transaction flow, compensation support, data binding and variable/argument scoping

• Updated visual designer

           · Easier to use by end users
           · Easier to rehost by independent software vendors (ISVs)
           · Ability to debug XAML Windows Server “Dublin” technologies

Provides standard host for Windows Workflow Foundation and Windows Communication Foundation applications

•   Prebuilt developer services

              · Message-based correlation
             · Content-based message forwarding service
             · Visual Studio templates

• Greater scalability and easier manageability

            · Enables scale-out of stateful workflow applications
            · Enhanced management and monitoring functions
            · Tracking store for workflow events

  Supports a set of Microsoft’s forthcoming modeling technologies currently code-named “Oslo”,I’m planning to write an article on Oslo as well.Keep exploring through these features and I’ll brief on Oslo in my coming article.
