Hi everyone

I have have an iis 7 webserver that about a dozen websites reside on. I have .NET 3.5 adn 4.0 installed on the server, but when I look at the application pool settings for the different sites, I only have an option to select .NET 2.0 and 4.0. Is there something wrong with my .net 3.5 framework on the server? If a developer asks specifically for 3.5, how do I specify this?

I appreciate any remarks. Thanks!

3.5 has extended 2.0 version, if you set your pool to 2.0 and you have 3.5 installed, you can host 3.5 applications because there is no separate setting for this. About 4.0 has some major changes, thats why they have a new selection for the application pool.

Hi stephanonline -- excellent, thanks!

That leads me to a follow up if you wouldn't mind ... if a developer needs AJAX controls, and I have installed 3.5, but the app pool is set to 2.0, would that mean they have access to the 3.5 ajax controls?

There is ASP.NET2.0 and .NET Frameworks 2.0, 3.0, 3.5 which are part of ASP.NET2.0. So if you enable ASP.NET2.0 in HELM, your .NET Framework 3.5 will work.

The only thing you are installing is the version for the System.Web.Extensions.dll, so it don't have to be included. If they use 2.0, they are limited to that.
