Difference between .NET 3.5 and .NET CF 3.5?

Is there an easy way to tell what is the difference between .NET and
.NET CF?  I keep running into brick walls when I try to do something in
.NET CF that I was able to do in .NET.

For example, DataGridView.  In a smart device project of VS2008, I see
DataGridView in the objectbrowser, but it is not a control that I see in
the toolbox.

Any help would be greatly appreciated.
