SNMP++ based c++ and c# ported to dotNet

There is another open source alternative, based SNMP++, the base is HP c++, the basic problem of this package is that is not fully ported to C#, but in the other hand has the power of c++, I tested this package a couple of years ago in a management product and works OK (ver1,2)

Includes all that you need if performance is the issue and if at last productivity is a must this can be a problem.
