I`ve heard that Visual studio.NET 2005 comes with ASP.NET 2.0. But I'm not sure what exactly I must hav to begin developing ASP.NET 2.0 applications

Can any give me some explanations? thanks...

i don't think u need much... except a machine with MS Windows 2000 and above and knowledge in MS platform development.

actually the framework 2.0 has asp.net 2.0... u don't need VS.NET 2005, cause vs.net 2005 doesn't come cheap... alternatively u can try
Visual Web Developer Express http://msdn.microsoft.com/vstudio/express/vwd/

software and hardware requirement can be found here
http://msdn.microsoft.com/vstudio/express/vwd/download/

but if u have vs.net 2005 installed... you are ready to start development at any time

Oh...so this mean i just hav to like install the .NET framework 2.0 and i can also use Visual Studio .NET 2003 to build ASP.NET 2.0 applications, rite?

Don't get him wrong... he means you can use [Visual Web Developer Express] to develop Asp.Net 2.0.

I think Visual Studio .NET 2003 can support until .NET 1.1 only!

yeah, don't get confuse on the framework versions with VS versions.

VS .NET 2002 - .NET 1.0 apps
VS .NET 2003 - .NET 1.1 apps
VS .NET 2005 - .NET 2.0 apps

VS web dev express can also make .NET 2.0 web apps, but not with code behind support. the codes were included within the html tags, kinda like the ones Macromedia has.

do correct me if i'm wrong.

Basically, you just need:

Notepad
Firefox with www.asp.net
.NET Framework 2.0
