  We present constraints on the density of halo dark matter candidates within
the solar circle based on the anisotropy in the high energy gamma-ray
background. The known galactic components of the gamma-ray background, in
particular the inverse Compton component, have been estimated more accurately.
We find the spectrum of the residual emission, after subtracting the galactic
component is inconsistent with emission from some of the proposed dark matter
candidates. We derive upper limits of 10^8 M_sun for the mass of diffuse gas
and 3*10^9 pc^(-3) for the number density of primordial black holes
contributing to the gamma-ray background.
