Ok. Now think in what you said. Does it really make sense? "lets include
an html parser in the C# compiler"... i don't think so.

Yes, CSC compiles the code, but doesn't generates this class from html.
This is because it is specific to ASP.NET how it parses the page and
creates the class. CSC's job is just to compile C# code, nothing more.

There are some classes in .NET that generates code from xml, and this is
probaly generated by them. But who parses the html and generates the
input to this tool is ASP.NET. Because ASP.NET is responsible for this,
not CSC.

Yes, because Win2003 comes with .NET 1.1.

1.1.4322.2032 is the version of .NET 1.1 SP1, not VS.NET 2005.

So, here we go. Please, forget about VS.NET. .NET doesn't depend on
VS.NET to work. It is just a tool to help you create applications.

You got this because you installed .NET 2.0. After installing it, all
your asp.net pages are compiled with .net 2.0. You can change this in
your website properties in IIS.

Because it is processed by .NET 2.0 =)

I can't understand how you got to this conclusion. "the numer is 2, not
1.. so csc is an html parser". this doesn't make sense.

What you discovered is that your code is generated by a different
version of the same tool, but you didn't see anything telling that csc
is parsin html pages.

When I tell you ASP.NET parses the page to generate the class, the real
process probably involves lots of classes in Microsoft.CSharp too. But
the one who parses the html and tell how to create the class is ASP.NET.
That is why you have System.Web.Compilation...

Of course it is compiled by csc. But not generated. That is why csc is
called "c sharp compiler" not "asp.net html parser".

Take a loot at this and this is probably how things work.

so asp.net generates common input to some parser which given an language
type generates the real output. csc only compiles it.
