  1. ASP to ASP.netMigration Harish Ranganathan Live Web Developer Evangelist | Microsoft India http://geekswithblogs.net/ranganh | hrangan@microsoft.com

  2. Understanding versions • ASP.NET 1.0 ~ Visual Studio .NET 2002 • ASP.NET 1.1 ~ Visual Studio .NET 2003 • ASP.NET 2.0 ~ Visual Studio 2005 • ASP.NET 3.5 ~ Visual Studio 2008

  3. DEMO ASP.NET and Visual Studio

  4. Key Changes • Scripting vs Code Behind • VB Script vs VB.NET/C# • Embedded in HTML / Code Behind ~ Beside • HTML Controls vs Server Controls • Virtual Directory vs Application

  5. DEMO Code behind ~ beside

  6. Server Controls • Generate HTML Code at runtime • Work on Post Back Model • Flexible server side handling • Stores post back data using View State • Can become heavier with extensive usage • Virtual Directory vs Application

  7. DEMO Server Controls

  8. Configuration • Web.Config for Application Settings • Machine.config for System Settings • Global.asax for Application Event Handling • Virtual Directory marked as Application • Needs ASP.NET Enabled in IIS 6.0 / 7.0 • Virtual Directory vs Application

  9. DEMO Configuration

  10. Chosing the Migration Model • Side by side: Classic ASP with ASP.NET Pages • All pages converted to ASP.NET • Both work well

  11. Horizontal Migration ASP.net ASP.net ASP ASP COM wrapper COM COM ADO / C++ ADO / C++

  12. Vertical Migration ASP.net ASP.net ASP ASP .NET Class Library COM ADO.NET ADO / C++

  13. How do I chose? • Depends on various factors • Long term approach must be Vertical Migration • Quick migration would be Horizontal, side-by-side with ASP and writing COM Wrapper

  14. What I miss in Vertical • Effort that went into designing DAL / BL • Business requirements, modifications to methods / return type data • Flexibility of an early roll-out

  15. What I miss in Horizontal • Pretty much everything i.e. Robustness, Databinding, ADO.NET, Performance etc., • Residing in unmanaged COM World • Disconnected architecture of ADO.NET (Applies to Data Set only)

  16. Top sites migrated to ASP.NET • Dell.com • Monster.com • MSN.com • LondonStockExchange.com • Microsoft.com (Yes, its equally difficult here)
