I have a project where I have to calculate distance between two UTM locations, I have E,N and Zone Letter and Number of each location.

I know i have to do something with ProjNet. I already use it to recalculate the new zone when i want to move an item to a new location by adding for example 2000 meters on easting near a zone cross.

Reproject your points to WGS84 lat long coordinates and compute the great circle distance between the points
