I found an interesting article (Microsoft Content Manager Server – live after SP2) from Joris poelmans about the SP2 in CMS nad ASP.NET 2.0.
For people working with Microsoft Content Management Server – I can definitely recommended you to use ASP.Net 2.0 in combination with MCMS. ASP.Net 2.0 makes CMS development a lot easier. To enable your CMS sites to use ASP.Net 2.0 ( and also SQL 2005 for that matter) you will need to install MCMS SP2. To get things started also take a look at the upgraded Woodgrove ASP.Net 2.0 application.
After deploying MCMS SP2, you should also take a look at the blog postings about these post-SP2 hotfixes:
If you want to take a look at the (not so) distant future, you should also take a look at the posting from Mark Harrison about how concepts from MCMS map on the SharePoint Server 2007 platform since web content management will be made available on this platform. I will shortly post some more information about the future of Web Content Management on the Microsoft platform and Microsoft Office SharePoint Server 2007 role in this.
