Where is IQueryable in the .NET Compact Framework?

Question

I have started to develop a repository using LINQ to SQL against SQL CE in a Windows project. This works fine. However, when I went to port the code over to .NET CF for a Windows Mobile application, the IQueryable does not appear to exist.

What is the best way to make this work across Mobile and Desktop?

It simply isn't there - most notably, because neither is Expression (although you can reintroduce pieces of that if you need).

Simply, you'll have to limit yourself to "regular" code for data-access (LINQ-to-SQL etc) / services (ADO.NET Data Services etc). Of course, when you have data from whatever source, you can still use IEnumerable<T>, so there are plenty of local options for data query.
