  We derive formulas for the Reshetikhin-Turaev invariants of all oriented
Seifert manifolds associated to an arbitrary complex finite dimensional simple
Lie algebra $\mathfrak g$ in terms of the Seifert invariants and standard data
for $\mathfrak g$. A main corollary is a determination of the full asymptotic
expansions of these invariants for lens spaces in the limit of large quantum
level. Our results are in agreement with the asymptotic expansion conjecture
due to J. E. Andersen.
