SharePoint 2010 and ASP.Net 4.0 on same IIS

Question

Can the IIS version in Windows Server 2008 R2 host all the following:

SharePoint 2010; ASP.Net 4.0; Classic ASP applications; VB6 compiled .dll web applications.

If so, can SharePoint 2010 be the Default Web application when accessing the server?

Thanks, Aaron

Answer 1

Sharepoint 2010 requires the .Net 3.5 framework.

I guess it's because a new SP version was being developed at the same time as the new .Net version, SP 2010 couldn't use .Net 4.0 yet.

Edit: here's the explanation in the words of the SharePoint Product Manager:

Unfortunately the release timeframes didn't work out to get SharePoint 2010 built on .NET Framework 4.0.

Hi Aaron

I'm not sure about VB6 compiled .dll web application, but the rest is no problem.

Classic ASP isn't installed by default, but it's just a feature to enable.

As SharePoint is running .Net 3.5 it needs to be in a seperate AppPool from your .Net 4.0 sites.

Which site is the default is just a matter of selecting which Web Site is serving port 80 without a host header.
