Question

I have 2 assemblies Combres and log4net

Both assemblies contain the same log4net.Appender namespace (internal code included) – I need to inherit log4net.Appender.AdoNetAppender.

How do I accomplish this.

Answer 1

Fully qualify the type. For example if you are trying to inherit from this class:

class MyAppender : log4net.Appender.AdoNetAppender

If you are trying to use / create an instance of this class:

var appender = log4net.Appender.AdoNetAppender;

If Combres and log4net both contain a type AdoNetAppender in the log4net.Appender namespace then you are in more trouble (and someone made a mistake – namespaces are designed to avoid these sorts of conflicts).

If this does happen then you can use the assembly reference “Aliases” property to resolve the conflict as described in What use is the Aliases property of assembly references.
