I'm trying to debug an UpdateMultiple plugin that uses pre entity images. What I'm finding when I step through the code is that PreEntityImagesCollection is null.
I ensured that I was on the latest version of the plugin registration tool and uninstalled then reinstalled the profiler without luck.
I was able to work around the problem but the release history for the plugin registration tool v9.1.0.167 says "Added support for IPluginExecutionContext2,IPluginExecutionContext3,IPluginExecutionContext4 to debugger." so it seems like this should work.
