DevForce Silverlight整合了Silverlight3的新特性，如DataForm, DataGrid, 和 Validation，并用我們現(xiàn)在流行的驗(yàn)證引擎無縫擴(kuò)展了Silverlight 3 Validation。所有這些特性使您能夠在短時間內(nèi)創(chuàng)建應(yīng)用程序，并減少代碼量和維護(hù)費(fèi)用。

為什么需要DevForce?

• 數(shù)據(jù)訪問
  Silverlight應(yīng)用程序獲取數(shù)據(jù)是很困難的。而為您的數(shù)據(jù)構(gòu)建遠(yuǎn)程域模型同樣是很困難的。但DevForce卻簡化了多層式架構(gòu)的持久化能力并且還提供了一個豐富的域模型，來建立您的應(yīng)用程序。您不需要編寫管道和基礎(chǔ)結(jié)構(gòu)代碼，只需專注于業(yè)務(wù)邏輯和用戶體驗(yàn)。
• 單個域模型
  您不用在多個地方重復(fù)您的業(yè)務(wù)邏輯。無論您是編寫客戶端，服務(wù)器端程序，DevForce的移動業(yè)務(wù)對象都能讓您只使用一個單一的域模型，同樣的域模型在我們的DevForce WinClient產(chǎn)品中也是可用的，因此您可能在應(yīng)用程序中采用不同技術(shù)而面臨許多問題，這些技術(shù)如WPF, WinForms, ASP.NET, 或 Silverlight*.
• 豐富的域模型
  DevForce確實(shí)可以為您提供豐富的業(yè)務(wù)對象。使用一個能夠表現(xiàn)您問題的域模型，它不只是單一的數(shù)據(jù)傳輸對象，因?yàn)樵谀莾耗仨氉龊盟械牟居浐椭匦聦?shí)施您的業(yè)務(wù)邏輯。
• 驗(yàn)證引擎
  驗(yàn)證您業(yè)務(wù)對象的正確性并給用戶提供有用的錯誤信息提示。支持交叉區(qū)和跨對象審定,并且無縫整合了Silverlight 3 validation。讓您的業(yè)務(wù)邏輯保持在業(yè)務(wù)對象范圍而脫離用戶界面。
• 實(shí)體框架集成
  微軟的下一代ORM框架必須實(shí)現(xiàn)標(biāo)準(zhǔn)化。DevForce是建立在Entity Framework之上的，它能夠在Silverlight上運(yùn)行，更加易于使用，同時還可添加你在這里看到的所有特性，甚至于更多。
• 響應(yīng)能力
  DevForce應(yīng)用程序響應(yīng)是很敏捷的。域模型如在Silverlight客戶端內(nèi)部運(yùn)行，那么客戶端緩存將減少訪問服務(wù)器的次數(shù)，數(shù)據(jù)壓縮則能減少網(wǎng)絡(luò)的延遲，還允許后臺處理異步查詢功能。
• 完整的N-TierLINQ支持
  在Silverlight客戶端應(yīng)用程序內(nèi)能夠?qū)崿F(xiàn)強(qiáng)大的LINQ功能。LINQ-to-Entities僅管理2層，而其他LINQ僅支持小范圍的查詢。與之相比，DevForce支持其所有。
• MVVM 和最優(yōu)方法
  DevForce是建立在良好的設(shè)計(jì)方法之上的，如MVC與MWM。它能使您方便地將您的UI和業(yè)務(wù)邏輯保存在屬于它們所屬的位置而不損失其易用性和功能特性。
• 離線操作
  在斷開或部分連接互聯(lián)網(wǎng)時可繼續(xù)使用您的應(yīng)用程序。將您的工作保存在一個單獨(dú)的存儲器中并在恢復(fù)后繼續(xù)您的工作。
• 多種數(shù)據(jù)源
  在一個單個的域模型中使用多個后臺的數(shù)據(jù)庫。使用對象屬性瀏覽交叉數(shù)據(jù)庫的關(guān)系。在一個分布式任務(wù)中，安全地保存您所有的修改。
• 可擴(kuò)展性
  客戶端緩存，連接池，以及無狀態(tài)和多核服務(wù)器，都為DevFroce應(yīng)用程序提供了完美的可擴(kuò)展性和容錯性。
• Web 服務(wù)
  在您的應(yīng)用程序中還支持其他的服務(wù)。DevForce可以在支持的業(yè)務(wù)對象上創(chuàng)建web服務(wù)，使您可以將他們集成到您的域模型中。

DevForce Silverlight integrates with the new Silverlight 3 features such as the DataForm, DataGrid, and Validation and seamlessly extends Silverlight 3 Validation with our popular Verification Engine. All of these features enable you to build applications in a fraction of the time and reduce code and maintenance costs.

Why DevForce?

• Data Access
  Getting data into a Silverlight application is hard. Constructing a remote domain model for your data is hard. DevForce simplifies n-tier persistence and provides a rich domain model on which to build your application. Stop writing plumbing and infrastructure code and focus on your business logic and user experience.
• Single Domain Model
  You shouldn’t have to duplicate your business logic in multiple places. The mobile business objects in DevForce enable you to use a single domain model whether you are writing client-side or server-side. The same domain model works with our DevForce WinClient product, so you can have multiple faces for your application in different technologies such as WPF, WinForms, ASP.NET, or Silverlight.
• Rich Domain Model
  DevForce provides you with rich business objects with real behavior. Use a domain model that represents your problem, not just flat data transfer objects, where you have to do all the bookkeeping and re-implement your logic.
• Verification Engine
  Verify the correctness of your business objects and provide helpful error messages to the user. Supports cross-field and cross-object validation, and is seamlessly integrated with Silverlight 3 validation. Keeps your business logic in your business objects and out of the UI.
• Entity Framework Integration
  Standardize on Microsoft’s next generation ORM framework. DevForce is built upon the Entity Framework, enables it to work in Silverlight, makes it easier to use, and adds all the features you see here plus more.
• Responsiveness
  DevForce applications are snappy. The domain model executes inside the Silverlight client, client-side caching reduces trips to the server, data compression reduces network latency, and asynchronous queries allow background processing.
• Full n-tier LINQ Support
  Use the full power of LINQ from within the Silverlight client application. LINQ-to-Entities only operates 2-tier, and other LINQ implementations only support a narrow range of queries. DevForce supports them all.
• MVVM and Best Practices
  DevForce is built around good architectural practices such as MVC and MVVM and enables you to conveniently keep your UI and business logic where they belong without sacrificing usability or functionality.
• Offline Execution
  Use your application while disconnected or partially connected to the internet. Save your work in isolated storage and resume working later.
• Multiple Data Sources
  Use multiple back-end databases in a single domain model. Navigate cross-database relations using object properties. Save all your changes safely in a distributed transaction.
• Scalability
  Client-side caching, connection pooling, and a stateless and multi-core enabled server provide DevForce applications with excellent scalability and fault-tolerant characteristics.
• Web Services
  Consume other services in your application. DevForce can create web-service backed business objects allowing you to integrate them into your domain model.
