Q: What is the difference between
```
System.Web.UI.WebControls.WebParts.WebPart
```
and
```
Microsoft.SharePoint.WebPartPages.WebPart
```
?
A:
```
Microsoft.SharePoint.WebPartPages.WebPart
```
is provided in MOSS 2007 to provide backwards compatability with MOSS 2003 webparts.  In MOSS 2007, it is recommended to use
```
System.Web.UI.WebControls.WebParts.WebPart
```
instead.
