In the past, we can only put the plugin assembly under <Navisworks Installation Path>\Plugins. In 2014, you have one more option to deploy the assembly in
"%APPDATA%\Autodesk Navisworks Manage 2014\Plugins
In the DevDays’s PPT, it says the new path is “%USERPROFILE%“. It is wrong. Sorry for this.
For programming, the script of post-build event could be:
xcopy /Y "$(TargetDir)*.*" "%APPDATA%\Autodesk Navisworks Manage 2014\Plugins\$(TargetName)\"
