Using ODP.NET the return type of "SELECT COUNT(*) ..." is decimal, not integer. So, using linq Count() function throw a conversion exception in

Projection\DataProjectorToValueList.cs

at

_destination.Add((T)valueToSet);

where T is long or int and valueToSet is ((object) decimal)

Thanks, Onorio

Hmm...

The thing is that the end-result has to be an int, as the type expected from Count() in C#/VB.NET is int. I'll see what I can do.

Reproduced. I'll see if I can wrap it into a cast to int. (or more in general: add a cast/convert to the .NET type for all aggregate functions)

Fixed in next build!
