3 Agenda Why building Business Application in Silverlight How to build Business Applications with: Silverlight Silverlight + ASP.NET based.net RIA Services How to use tools to improve productivity

4 Trends In Today s Business Application RIA Data

5 Why RIA? Rich UI experience Interactive UI model to operate data Internet application Wide Internet deployment Cross boundaries between platforms and browsers Application logic Productive development experience Easy to build, reuse, customize and extend

6 Silverlight for RIA Rich Internet application controls More than 60 built-in controls More data visual controls at Easy Internet deployment Various platforms and browsers support Productive development experience.net runtime and Base Class Library support Interactive UI model support Powerful tooling support

7 Data! Data!! Data!!! Business applications are all about data Web based business applications have challenges: Moving data between layers and boundaries Define resources and operation Validate data in presentation and mid-layer Share services between different applications

8 Build Business Application in Silverlight Create and Connect database Write validation logic at server Add service reference into the client Bind data to the UI Build update mechanism Server Business Objects Client Business Objects Plumbing Code Server Create data source and data access layer (DAL) Create a service to marshal data Add client side business logic Add data paging, sorting, filtering, etc. Create UI Client

9 Build Business Application in Silverlight

10 Better Silverlight for Business Application Business Logic Framework Business Logic Data Validation Data Loading Application Services Business Controls Basic Framework Networking / Services Data XML LINQ Controls Control Model Data Binding Navigation Basic Platform CLR Core UI Engine

11 Simplify N-tier Business Application Create and Connect database Write validation logic at server Add service reference into the client Bind data to the UI Build update mechanism Server Business Objects Client Business Objects Plumbing Code Server Create data source and data access layer (DAL) Create a service to marshal data Add client side business logic Add data paging, sorting, filtering, etc. Create UI Client

12 Simplify N-tier Business Applicaton Create and Connect database Support basic data analysis, sorting, paging, testing, etc. Shared Business Objects Create data source and data access layer (DAL) Connect data source and UI with a set of business objects Server Client

13 .NET RIA Services Work on existing Client / Server technology Silverlight Client ASP.NET Server Unified Client / Server model The same set of business objects In the same application project Simplify data moving Expose data by business objects Provide plumbing for data Various data sources Entity Framework, ADO.NET Data Services, Web Services, etc. Client View Business Objects Business objects Data Access Layer Server

14 Building Business Application In.NET RIA Services

15 Key Concept in.net RIA Services Shared Code Shared Code Client View DomainContext Data Access Layer Server EntityList Code Gen DomainService Metadata DomainService Main class at Server for data operation DomainContext Client class to invoke methods defined in DomainService EntityList A collection for data binding Metadata Provides data validation on data entities in a flexible way Shared Code Share business logic between layers and boundaries

16 Data Validation In.NET RIA Services

17 Meet More Needs In Business Apps Custom operation Authentication Validation Paging Data filtering at Server Etc.

18 Custom Method and Authentication In.NET RIA Services

19 Better Tool, Better Life Based on Microsoft Visual Studio Easy to update with add-on package Familiar development experience in IDE Basic tooling support in code generation More tooling support in Visual Studio 2010 Data Source Window support Live IntelliSense

20 Summary Trends in today s business application RIA: Rich interactive Internet Application Data: complex data operation Silverlight enables RIA in business application.net RIA Services provides complete business application solution Silverlight and ASP.NET based The same set of business objects to simplify data operation Built-in data validation mechanism against metadata Tooling support improves productivity
