  We present a flux formulation of Double Field Theory, in which geometric and
non-geometric fluxes are dynamical and field-dependent. Gauge consistency
imposes a set of quadratic constraints on the dynamical fluxes, which can be
solved by truly double configurations. The constraints are related to
generalized Bianchi Identities for (non-)geometric fluxes in the double space,
sourced by (exotic) branes. Following previous constructions, we then obtain
generalized connections, torsion and curvatures compatible with the consistency
conditions. The strong constraint-violating terms needed to make contact with
gauged supergravities containing duality orbits of non-geometric fluxes,
systematically arise in this formulation.
