  1. Microsoft. NET Microsoft introduced .NET technology to provide : Support for previous versions of ASP Ease of integration between ASP.NET and ASP A simpler programming model No need to keep binary compatibility between different versions of components “DLL Hell” Assemblies are not registerd

  2. Technologies of the Microsoft .Net Framework • Common Language Runtime Engine • Microsoft Intermediate Language (MSIL) • JIT (Just-In-Time) Compilation • Unlike Java Virtual Machine, which interprets code at runtime, MS.NET runtime compiles in machine native code, which provides better performance • Platform independence • Source code is not compiled to binaries for a particular platform

  3. Technologies of the Microsoft .Net Framework Cont’ • Language independence • C#, Visual Basic, Jscript, C++ • ASP.NET Web forms (pages) • Server side scripts • Client side controls like Standard HTML and Java Script

  4. Technologies of the Microsoft .Net Framework Cont’ • ASP.NET Controls • Automatic Browser type detection • Provide a layer of abstraction to HTML • ViewState Management • Http is a stateless protocol • Maintaining state Automatically • In ASP.NET, Unlike ASP, all controls remember their state by default • ASP.NET doesn’t use cookies

  5. Technologies of the Microsoft .Net Framework Cont’ • Validation Controls • MS.NET provides built-in validation controls without client-side code

  6. ASP.NET Web Forms • Web forms contain blocks of code that are processed on the server • Generate HTML • The entire page is compiled on the server. • This reduces the server response time • The compiler can find potential errors that might be overlooked until runtime in interpreted languages

  7. ASP.NET List Controls Provide an easy way to create HTML that contain the contents of a data source • In ASP, we have to use loops walk through the data

  8. ASP.NET Controls Cont’ • Data Source can be • ArrayList, Hashtable, SqlDataReader, … • DataView is a recordset for storing large amounts of data (XML) • List controls: • Repeater: used to display items in a list • DataList: a template-driven list control • DataGrid: a table-driven list control

  9. Validation Controls • RequiredField Validator • Range Validator • Compare Validator • RegExp Validator • Custom Validator • ValidationSummery

  10. Benefits of MS.NET Framework • Fewer lines of code • Complete compilation • ASP is interpreted • Output, Data and Fragment Caching
