Shailesh,

I have not see that include syntax in ASP.NET as it was in classic ASP.
If I wanted to include static content within a ASPX page, I would do
this...

1) Create a User Control called Include.ascx
2) Add a Literal control to that User Control
3) Add a Property to the code-behind called Virtual or File as a String
4) For the Load handler, I would read the contents of that file and set
the Text property of the Literal control

That would bring the contents of that control into your page.  In the
ASPX page, you would reference the User Control like...

<uc1:Include ID="Include1" runat="server" Virtual="~/file.html" />

And to speed things up a little, I would use System.Web.Caching to hold
the contents of the file with a dependency on the referenced file.

Once you have this User Control you can use it for any website you
build.

Shailesh,

I thought this was interesting so I created a sample ASP.NET 2.0
website with the User Control I described here.

You can download it here.
