vivek_cs:Would I able to see my .NET Framework 3.5 in IIS web site properties through asp.net version tab.
No. ASP.NET 3.5 is the ASP.NET 2.0 CLR, so you set any ASP.NET 3.5 app as 2.0 in the application process. Think of ASP.NET 3.5 as really ASP.NET 2.0 but with extra cool stuff. And blame Microsoft for confusing numbering.
vivek_cs:Although i m hoping .net framework 3.5 would be backward complaince.
Using 3.5 will run any 2.0 app except that you need to compile to the 3.5 framework. You also will need to use VS/VWD 2008 to do that.
For more on ASP.NET versions, see the forums at www.asp.net. Same login as here.
