This Letter describes the current most precise measurement of the W boson pair production cross section and most sensitive test of anomalous WW\ensuremathγ and WWZ couplings in pp collisions at a center-of-mass energy of 1.96 TeV. The WW candidates are reconstructed from decays containing two charged leptons and two neutrinos. Using data collected by the CDF II detector from 3.6 fb^\ensuremath-1 of integrated luminosity, a total of 654 candidate events are observed with an expected background of 320\ifmmode±\else\textpm\fi47 events. The measured cross section is \ensuremathσ(pp\ensuremath→W+W^\ensuremath-+X)=12.1\ifmmode±\else\textpm\fi0.9(stat)_\ensuremath-1.4+1.6(syst) pb, which is in good agreement with the standard model prediction. The same data sample is used to place constraints on anomalous WW\ensuremathγ and WWZ couplings.
