Method not found

[Fred]

Hello,

I get this strange error in the code of a very simple aspx page just
called to download a file.
Do you have any idea about it ?
(The same code works fine on another server)

Server Error in '/' Application.

This overload appears to have been added in version 3.5. So it is not
available in 2.0.

Yes !
Thanks a lot Mufaka.
I didn't think about this at all but yes, I recently installed the 3.5
version on my development computer and on the server to try VS 2008.
Unfortunatly, seems Intellisense proposed the 3.5 overload when I was
using VS 2005 :-(
Thanks again for this fast answer, I will be very careful now.

If you want, though, to use any 3.5 features, just change the target version
to 3.5 in your project.
