 Posted by ArticlesMaint on 9/24/2009 | Category: SharePoint Interview questions | Views: 4241

Ok, first let’s talk about a bit of history. ‘WebParts’ was born when WSS 2.0 was first introduced. In ASP.NET 2.0 framework new version of ‘WebPart’ was built which can run with out WSS. WSS 3.0 uses the ASP.NET 2.0 ‘WebPart’ framework.

So some quick points:-

  • If you are doing new development using WSS 3.0 you should use ASP.NET 2.0 ‘WebPart’ framework.

  • If you want backward  compatibility you an use ‘Microsoft.SharePoint.WebPartPages.WebPart’  class.

So the decision will  be more based on what level of back ward compatibility you are looking for.

Below sheet shows the new WebPart classes as compared to SharePoint Backward compatible class.
