Answer 1

Entity Framework can't translate that type of conversion to SQL.

Is there any chance you could alter your data structure to use proper data types such as actual DateTime types? For large data volumes conversions like that will affect performance.

I would recommend either changing your data model types to avoid these conversions, or if the amount of data will always be small, then get the data first, and later use Linq to Objects.
