I wondered why.\r\n\r\nSo, I tracked down the change in question: https://github.com/SharpRepository/SharpRepository/commit/8c1f9aaf5c23e82e91621adf8762ce6c71d620a9#diff-d24380b902ea13a619155432be3b7b18R841\r\n\r\nLooks like this was done as part of a change to handle differences in NETSTANDARD vs NETFX reflection/types. \r\n\r\nBut, in our case, broke what was working.\r\n\r\nIs that `Compile()` necessary? If not we should probably revert to the old method which doesn't throw (See below where `predicate` is the `Func\u003c\u003e`).\r\n\r\n![image](https://user-images.githubusercontent.com/811086/40167855-f1354d68-5976-11e8-8d95-0f70b84ef429.png)\r\n\r\n","author":{"url":"https://github.com/tynorton","@type":"Person","name":"tynorton"},"datePublished":"2018-05-17T09:15:29.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":7},"url":"https://github.com/204/SharpRepository/issues/204"}
