import numpy as np
from numpy.core.umath_tests import inner1d
V = np.random.random_sample((10**6,3,)) # 1 million vectors
A = np.sqrt(np.einsum...

Update relationships when saving changes of EF4 POCO objects

Other proposed solution
Instead of real Merge functionality EF team provides something called Self Tracking Entities (STE) which don't solve the problem. First of all ...
