I review the Chern-Simons formulation of higher-spin (hs) gravity in D=2+1, the notion of AdS-asymptotic solutions and the idea of the corresponding asymptotic symmetry algebra. The connection to the Drinfeld-Sokolov reduction allows to find a method to systematically compute the asymptotic symmetry algebra of generic 3-dim bosonic hs gauge theories in a Virasoro-primary basis. I show how to apply this procedure to a one-parameter family of hs theories with infinitely many higher spin fields that is of crucial importance in the recently conjectured AdS-dual for $W_N$ minimal models by Gaberdiel and Gopakumar.
