· Different virtual directories can run different versions of the ASP framework.
· Forms authentication cookies can be used between 1.1 and 2.0.
o 2.0 uses AES encryption by default
o To have this work change the machine Key in web.config. To do this explicitly set the validation key and machine key for 1.1. For 2.0 change the decryption attribute to “3DES”.
· New reserved directories:
o /app_code – for code
o /app_data – for data
o /app_themes – for skins
o /app_webreferences – for WSDL
o /app_localresources – for local page resources
o /app_globalresources – global resources
· ASP.Net has full XHTML compliance
· Client-side script files are now encapsulated as resources.
o Js files are new referenced
o You cannot edit client-side scripts anymore. Use expanded client-side scripting instead.
· Potential for Naming collisions. 2000+ new classes. Common names include roles, membership and theme
· Visual Studio 2005
o No more project file
o Web projects are no longer compiled into a single dll.
o Can update pages/code while using the debugger
o No need to recompile when making changes
o Web projects can be written in multiple languages.
· VS 2003 to VS 2005
o One way conversion
o Always enable backup and check back into source code control when stable.
o The conversion tool logs everything that it does.
o No more code behind dlls. Code moves into the app_code directory
· New code behind model. Designer generated sections are gone! Control definitions use partial classes.
o Still enables definition of a custom base pages + control classes.
o CodeBehind attrbute is replaced by the CodeFile attribute in 2.0
· When sharing a dll to access the control in 1.1 you now have to share the ascx file. Hmmm. Dunno if I like that. I have to try this out.
· Dynamic compilation model.
o No more code behind assembly
o Compile pages & controls on demand.
· Precompilation – Compiles code into assemblies
o Use aspnet_complier executable for precompilation. Options include aspx markup is removed or aspx markup is preserved. Now this I like.
