This query in LINQPad against Northwind.

Product.Any(p => p.Discontinued)

gives

InvalidCastException: Unable to cast object of type 'SD.LLBLGen.Pro.LinqSupportClasses.ExpressionClasses.EntityFieldExpression' to type 'SD.LLBLGen.Pro.LinqSupportClasses.ExpressionClasses.FilterExpression'.

but this

Product.Any(p => p.Discontinued == true)

is fine as is

Product.Count(p => p.Discontinued)

What gives?

linq 3.0.11.113 and orm support 3.0.10.1201

I think because Count() neads a field, but Any() expects an expression.

No they both take the same parameter System.Linq.Expressions.Expression<Func<TSource,bool>> predicate

Bug

Fixed in attached dll.

the following bugs were fixed in this dll: Linq: A boolean predicate in an All/Any call using a not (e.g. .Any(p=>!p.Discontinued)) failed. Linq: A boolean predicate in an All/Any call without comparison with true/false failed. Linq: Testing for NULL on an entity in a projection combined with a conditional expression (e.g. IIF() / ?: ) failed with an exception.
