Answer 1

If you ever start implementing any standardized protocol, the first step is to read the standards defining it. In case of SNMPv3. the relevant standards are

RFC:s

• 3411,
• 3412,
• 3414,
• 3414,
• 3515,
• 3416,
• 3417 and
• 3418

The good (and bad) thing about RFC's is that they usually very clearly state what you MUST, SHOULD, MUST NOT, SHOULD NOT and MAY do in your implemention.

Answer 2

There is an excellent open-source implementation for the .NET framework called SharpSnmpLib. It can implement a normal SNMP server, and it allows you to load your own custom MIBS.

A couple of tips:

• You can find existing MIB's at oidview or the Cisco Mib Browser
• Avoid v3 and the RFC's that belong to it (in fact, I'd avoid the RFC's at all, they're confusing and cover many areas that were not adopted)
• Test early and often with machines as close to the production setup as you can
