I am going to install the framework 3.5 on to my hosting machine

No, the 2.0 applications should be unaffected as the two live side-by-side - same as 1.1 and 2.0. Beta 2 should have a Go-Live license so you can use it in production however you cannot use anything pre-beta 2.

However, you might want to backup just in case.

One additional note is that NETFX 3.5 relies on and include NETFX 2.0 (sp1 beta) and NETFX 3.0 (sp1 beta).

While these are intended to be compatible, this level of update (service pack) does change more code than just a hotfix.

I recommend you test an production applications well before running them with NETFX 3.5 installed.

Having said that, at Microsoft we are running a lot of 2.0 apps and web sites on NETFX 3.5. As usually, please let us know of any unusual behaviors or bugs.

After install of 3.5 .net on my developmental machine (win 2003 rc2 fully patched, IIS 6.0), .net 2.0 sp1 breaks httpcontext . Errors related to integrated pipeline:

'System.Web.HttpContext.Current.CurrentNotification' threw an exception of type 'System.PlatformNotSupportedException'

base {System.NotSupportedException} = {"This operation requires IIS integrated pipeline mode."}

This breaks my .net 2.0 code that uses HttpContext. And runs on the developmental machines IIS or the Dev IIS Server. It appears that IIS 6.0 doesn't support Integrated Pipeline and the .net 2.0 sp1 is installing the wrong dlls for Server 2003 IIS 6.0

Thanks
