> Using .NET 2.0, over SQL Server 2005
> one of the latests changes (I guess) was that "select new Projection(... sum(s.Data)) ... " would assume "long" for the sum element, rather than int.
> So if the projection has "int" in the constructor an exception will occur. 
> However, current users gets a non informative error message.
> attached here a patch that would add the expected types for the contructor's parameters, so it would be easier to fix.
> I was not able to build the solution due to some local problems with nant, so it should be tested.
