I can't help you with your Visual Studio problem because I don't use it. I can tell you, though, that your formula for age in years is incorrect simply because of the way DATEDIFF works. You need to use something like the following...

ALTER FUNCTION [Util].[AgeInYears]
        (
        @StartDT DATETIME, --Date of birth or date of manufacture or start date.
        @EndDT   DATETIME  --Usually, GETDATE() or CURRENT_TIMESTAMP but
                           --can be any date source like a column that has an end date.
        )
RETURNS TABLE WITH SCHEMABINDING AS
RETURN
SELECT AgeInYears = 
            DATEDIFF(yy, @StartDT, @EndDT)
          - CASE --If anniversary date hasn''t happended yet this year, subtract 1.
            WHEN DATEADD(yy, DATEDIFF(yy, @StartDT, @EndDT), @StartDT) > @EndDT
            THEN 1
            ELSE 0
            END
;

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
