Best way to make WPF ListView/GridView sort on column-header clicking?

Solution
It all depends really, if you're using the DataGrid from the WPF Toolkit then there is a built in sort, even a multi-column sort which is very useful. Check more out here:

Alternatively, if you're using a different control that doesn't support sorting, i'd recommend the following methods:

Problem
There are lots of solutions on the internet attempting to fill this seemingly very-basic omission from WPF. I'm really confused as to what would be the "best" way. For example... I want there to be little up/down arrows in the column header to indicate sort direction. There are apparently like 3 different ways to do this, some using code, some using markup, some using markup-plus-code, and all seeming rather like a hack. Has anyone run into this problem before, and found a solution they are completely happy with? It seems bizarre that such a basic WinForms piece of functionality is missing from WPF and needs to be hacked in.
