Popis:	In this paper we consider the Baum-Connes correspondence for the affine and extended affine Weyl groups of a compact connected semisimple Lie group. We show that the Baum-Connes correspondence in this context arises from Langlands duality for the Lie group. Comment: Updated to take account of a number of small changes suggested by Maarten Solleveld, and to include a reference to his thesis, which contains a number of very interesting examples including the illustrative example given in section 2 of our paper
