@TheQuake - thanks for reporting. EPPlus does not throw an Exception with this message from what I can see. It seems to come from the System.ComponentModel.DataAnnotations.Display attribute.

Can you provide some more information that might help us to replicate this issue? The code for the T class that you use in LoadFromCollection<T> would be useful.

@swmal - Thanks! It's a POCO that had an attribute over a single read-only (get only) property, specifically: ( [Display(Name = "Product")] ). Since the exception was related to annotations, I removed it & voila, it works now. I don't need that decoration, but if you wish to pursue this further, let me know.
