ASP.net version in Sharepoint

I heard that Sharepoint use asp.net but wh开发者_StackOverflow社区ich asp.net? Is it classical or MVC version?

MOSS 2007 - ASP.NET 2.0
SharePoint 2010 - ASP.NET 3.5

I'm not sure what classical means exactly but it definitely is not MVC.

From the whitepaper: The SharePoint 2010 Developer Platform

The 2010 release of SharePoint can be viewed in three parts:

1. Microsoft SharePoint Foundation 2010: The basis of everything else in SharePoint, SharePoint Foundation 2010 is the successor to Windows SharePoint Services 3.0.
2. Microsoft SharePoint Server 2010: The successor to Microsoft Office SharePoint Server (MOSS) 2007, this product contains a group of technologies that address more specialized problems. While SharePoint Server 2010 is built largely on SharePoint Foundation 2010, it’s a separate product—using it requires purchasing a license.
3. SharePoint Online: A Microsoft-hosted version of SharePoint technology, this offering lets both users and developers use SharePoint’s functionality without installing any on-premises SharePoint software.

On the used technology for SP2010 (from the Glidepath):

SharePoint Foundation 2010 uses Microsoft ASP.NET 3.5, even if a later version of ASP.NET is also installed on the front-end Web server.

As for the former MOSS2007 version

...with the release of the 2007 Microsoft Office system, Microsoft provides products and technologies such as Windows SharePoint Services 3.0 and Microsoft Office SharePoint Server 2007 that are built on top of ASP.NET 2.0.
