Windows SharePoint Services SP2 does support the .NET Framework 2.0, CLR 2.0 and ASP.NET 2.0; therefore you can build ASP.NET 2.0 Web Parts using Visual Studio 2005 and deploy them on Windows SharePoint Services SP2; however, this process is not as straight-forward as it sounds here!
To leverage ASP.NET 2.0 Web Parts in Windows SharePoint Services, a wrapper Web Part must be written to make the ASP.NET 2.0 Web Part appear to be a Windows SharePoint Services Web Part. After this is done, your ASP.NET 2.0 Web Part should function normally within your Windows SharePoint Services pages. Wrapper Web Parts will not be required in the next version of Windows SharePoint Services or the next version of SharePoint Portal Server (code named Office "12" SharePoint Servers), which both natively support ASP.NET 2.0. For wrapper Web Parts, you might want to investigate http://www.smartpart.info/default.aspx. You can grab the latest version of SmartPart (called Son of SmartPart) off of GotDotNet at http://www.gotdotnet.com/workspaces/releases/viewuploads….. This SmartPart should allow you to contain ASP.NET 2.0 Web Parts on WSS SP2 sites inside Web Part Zones J – I suggest you give it a shot!
However, SharePoint Portal Server 2003 SP2 DOES NOT support .NET Framework 2.0. However, the next major release of SPS will be fully based on ASP.NET 2.0 and will make use of its many features.
My opinion around the matter is this:
- If you need to deploy the Web Parts on SPS 2003 then it’s best to continue building native .NET Framework 1.1 Web Parts until the next major release of SPS is out.
- If some features in ASP.NET 2.0 Web Parts are necessary for your application at this time, and you can afford to deploy the Web Parts on Windows SharePoint Services instead of the full-fledged SPS (i.e. a case where the enterprise features of SPS are not needed), then you can build ASP.NET 2.0 Web Parts and deploy on WSS SP2 as described above.
Finally, I would suggest that for Enterprise-Level Portals you continue to use SharePoint Portal Server 2003 SP2 and build native Web Parts on .NET Framework 1.1 like you would normally do until the next major release is out.
