Have a look at http://www.linqpad.net/[^]

LINQPad lets you interactively query databases using linq - it's a useful tool for trying out queries.

I'm also pretty certain that I would use ExecuteStoreQuery[^] and just execute the query using your SQL.

I expect that you know that your query will be translated back to SQL because SQL server hasn't got a clue about linq.

It's LINQ you are using. use DateTime.Now to get the current date, and then compare it from there. Do you know how to write LINQ queries ?

var team = from a in Entity.Report.Where(a=> a.Active == true) select a;

a.member in ('Free','PartTime') and (DATEDIFF(m,asofdate,getdate())>0 or AsOfDate is null)
Please add this in LINQ format in where statement.

var team = from a in Entity.Report.Where(a=> a.Active == true && (a.member == "Free" || a.Member == "PartTime") && (a.AsOfDate == null || a.AsOfDate > DateTime.Now)

That is an absolute wild guess.

var team = from a in Entity.Report where ( (a.Active == true) && (a.Member == "Free" || a.Member == "PartTime") && (a.AsOfDate > DateTime>now || a.AsOfDate == null))
