Compare Date Part only of BSON using LINQ

Hello Everyone,

I have just started learning and developing my first Mongo driven application. I am getting a serialization error
when trying to compare date part of a datetime property in a collection.
Both _shiftCollection.Scheduled Start and currentDate are in UTC format.
I have found numerous ways using Mongo Query, but I prefer my logic to be
strongly typed.

[What I have tried so far]

var found = await (from f in _shiftCollection.AsQueryable()
                                       where f.ScheduleStart.Date == currentDate.Date
                                       select f).CountAsync();

{document}{ScheduleStart}.Date is not supported.

Any help are greatly appreciated. TIA.
