Abstract: \font\msbm=msbm10 \def\bbR{\hbox{\msbm R}} We give an idea of constructing irreducible unitary representations of Lie groups by using Fedosov deformation quantization in the concrete case of the group $ Aff(\bbR)$ of affine transformations of the real line. By an exact computation of the star-product and the operator $\hat{\ell}_Z$, we show that the resulting representations exhausted all the irreducible representations of this groups.
