The LHC has already provided many relevant measurements for the determination of parton distribution functions (PDFs). Measurements of the W and Z lepton distributions are of interest for flavor separation and in particular for the determination of the relatively poorly constrained strange quark distribution. In this contribution we shall discuss the computational developments that allow for the efficient inclusion of LHC data into the NNPDF framework consistently at NLO for all observables, and we study the constraints of the LHC W and Z data on the strangeness content of the proton.
