Cannot convert type `UnityEngine.Object[]' to `System.Collections.Generic.IEnumerable<T>'

Unity Engine

Hi all
Im sure this has been asked before but Im upgrading from 5.0 to 5.5 and got this error upon loading in the editor.
its line 47
error CS0030: Cannot convert type UnityEngine.Object[ ]' to System.Collections.Generic.IEnumerable’

Any suggestion would be helpful, the original designer of the code isnt at the studio anymore so Im flying blind but hopefully there is a simple upgrade fix to this error.

Thanks in advance.

I wouldn’t think this would result from an upgrade, in a “How did this ever work?” sort of way.
Try this?

        return (IEnumerable<T>) Object.FindObjectsOfType<T>();

awesome that did it thanks. And yea I agree, I think it was from 4.0 and never carried over. Its an old Wii U build we are converting to a new project.
