I know that it's possible to mix ASP & ASP.NET 1.1 in the same
website/application so long as they are in separate frames (iframes). This
also holds for mixing ASP & ASP.NET 2.0 pages. But what I haven't tried
is mixing ASP.NET 1.1 & ASP.NET 2.0 pages in the same website/application
but each page in different iframes.

I don't think it's possible to to have both ASP.NET 1.1 & 2.0 pages in
the same website since IIS defines which ASP.NET version to use. Does
anyone know a way to make IIS use ASP.NET 1.1 for certain pages, and
ASP.NET 2.0 for other pages?

Probably one can host the ASP.NET 1.1 website, and link in the iframes
of ASP.NET 2.0 pages from another website in the same IIS server. But
that's just looks clumsy.

Although I know there are some backwards compatability problems between the different frameworks, the conversion and recompilation shouldn't be too bad? Are there simply too many pages to make them all 2.0? The only way I'm aware of to mix with 2.0 is to serve from different sites, but I'm no expert...

You can only set an application to run on one framework, so you're going to have to choose between 1.1 and 2.0...


But if you do not have a lot of 2.0 specific code (such as no generics) then you might be able to compile your website all in 1.1 through visual studio 2005 with a program called MSbee


Other than that you could convert the code. If the problem you're having with is converting 1.1 Website projects into 2.0 Website Applications then they also have an add-in for that.. Here


Good Luck!
