Migrate ASP.NET web application from 1.1 to 4.0

Hi,

I am in process of migrating asp .net web application from 1.1 to 4.0 framework. The application has few reference dlls that was compiled in 1.1 framework (so its manifest has reference to 1.1 framework dlls in GAC). Following is my understading when 1.1 reference dll is loaded in run time.

1. CLR 4.0 will be used to load and execute reference dll compiled in 1.1 framework.
2. It is not required to install .net framework 1.1 in server.

Thanks,
Santhosh

AFAIK,you could run into issues, depending on where you deploy it ... for example, you may have to explicity install 1.1 ... for example, i've not looked at win8 yet, so i do not know if 1.1 will shipped installed ... also, because 1.1 is ancient (in computer years), it appears that Microsoft soon will no longer supports 1.1: http://support.microsoft.com/lifecycle/search/default.aspx?sort=pn&alpha=.net+framework

bottom: you may encounter compatibility issues as some future date.
