Short answer, yes, you must use VS 2003 to develop the 1.1 program.
Long answer, it might be possible to build your project using VS 2005 (and
therefore 2.0), and then configure the application to use the 1.1 version of
the runtime. You're probably going to run into all sorts of problems doing
this (espcially if this is a WinForms app).
