  As part of the GLOSTAR (GLObal view of STAR formation in the Milky Way)
survey, we present the high-resolution continuum source catalog for the regions
(l = 2-28, 36-40, 56-60, &|b|<1.0), observed with the Karl G. Jansky Very Large
Array (VLA) in its B-configuration. The continuum images are optimized to
detect compact sources on angular scales up to 4", and have a typical noise
level of 1sigma ~ 0.08mJy/beam for an angular resolution of 1", which makes
GLOSTAR currently the highest resolution as well as the most sensitive radio
survey of the northern Galactic plane at 4-8GHz. We extracted 13354 sources
above a threshold of 5sigma and 5437 sources above 7sigma that represent the
high-reliability catalog. We determined the in-band spectral index (alpha) for
the sources in the 7sigma-threshold catalog. The mean value is alpha=-0.6,
which indicates that the catalog is dominated by sources emitting non-thermal
radio emission. We identified the most common source types detected in radio
surveys: 251 HII region candidates (113 new), 282 planetary nebulae (PNe)
candidates (127 new), 784 radio star candidates (581 new), and 4080
extragalactic radio source candidates (2175 new). A significant fraction of HII
regions and PNe candidates have alpha<-0.1 indicating that these candidates
could contain radio jets, winds or outflows from high-mass and low-mass stellar
objects. We identified 245 variable radio sources by comparing the flux
densities of compact sources from the GLOSTAR survey and the Co-Ordinated Radio
`N' Infrared Survey for High-mass star formation (CORNISH), and find that most
of them are infrared quiet. The catalog is typically 95% complete for point
sources at a flux density of 0.6 mJy (i.e. typical 7sigma level) and the
systematic positional uncertainty is <= 0.1". The GLOSTAR data and catalogs are
