It doesn't look like the plugin profiler works for Retrieve and RetrieveMultiple messages. I cannot find any documentation saying it shouldn't past a couple of blog posts here and there. Does anyone know for sure?
The error I get when trying to profile a very simple plugin on retrieve or retrievemultiple is:
Unexpected exception from plug-in (Execute): PluginProfiler.Plugins.ProfilerPlugin: System.TypeInitializationException: The type initializer for 'PluginProfiler.Plugins.ServiceWrappers.ServiceProviderWrapper' threw an exception.
