Query fails: "Cannot perform an aggregate function on an expression containing an aggregate or a subquery."

One of my LINQ queries fail with a Syntax Error and the message : "Cannot perform an aggregate function on an expression containing an aggregate or a subquery."

I'm using MS SQL Server 2008 R2 and DO 4.4.

You can find the LINQ code @ here

Hello TimM,

Could you please provide us with the resulting SQL? As I understood, the exception occurs on SQL Server side during the command execution. But if there is a chance, it would be great to get a sample that fails so we could thoroughly investigate the query translation.

Thanks in advance.

Sample would be hard at the current time (lacking the time at the moment) but I could give you the full exception (including the 'query' it produced).

Just tell me where to send it to (email, ...)

Please, send it to support@x-tensive.com

Thanks.
