CF build is based on Change Set 47068.

Changes from 4.0:

1. The Agent and the Browser now support SNMP v3.
2. The Agent, the Browser and the Compiler supports both .NET/Windows and Mono/openSUSE now.
3. VB.NET samples are added.

General

SELECT METHODS WHERE CodeWasChanged OR WasAdded

The codebase keeps evolves fast, and the picture shows a lot,



You can see a lot of highlighted areas, because

1. We migrated to Visual Studio 2010, so many generated code has been changed.
2. We changed a lot of GUI code in order to support Mono/openSUSE.
3. Agent side SNMP v3 support introduces many underlying changes in the Library.
4. Browser side SNMP v3 support introduces a few changes in itself.

New Core Public Types

SELECT TYPES FROM ASSEMBLIES "SharpSnmpLib","SharpSnmpLib.Controls", "SharpSnmpLib.Mib" WHERE IsPublic AND WasAdded

Only three new types are introduced in 5.0,

• MalformedMessage: It is used to represent an SNMP v3 message received by the listener, which cannot be decrypted successfully due to several reasons.
• DecryptionException: An exception raised when an SNMP v3 message cannot be decrypted successfully.
• ListenerBinding: We introduce this class, so you can ask a Listener class to monitor on several IP address:port number bindings.

New Assemblies

SELECT ASSEMBLIES WHERE WasAdded
Only one assembly is added to our binary release package. That is snmptranslate, a utility to show how to use compiled MIB documents to do OID translation.

New Public Types

SELECT TYPES WHERE WasAdded AND IsPublic
We have a few new types here except for the three mentioned above,

• OutputPanelAppender: This is a custom log4net appender used in the Browser and the Compiler. It logs all necessary information into the output panel.
• RollingFileAppender: This is a custom log4net rolling file appender that outputs log file names in IIS similar pattern.
