In a WPF app I'd like to check if a return of a LINQ to SQL query contains some records, but my approach doesn't work:

        TdbDataContext context = new TdbDataContext();
        var sh = from p in context.Items where p.Selected == true select p;

        if (sh == null)
        {
            MessageBox.Show("There are no Selected Items");
        }

Where am I wrong?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More

LINQ to SQL and missing Many to Many EntityRefs

Ran into an odd behavior today with a many to many mapping of one of my tables in LINQ to SQL. Many to many mappings aren’t transparent in LINQ to SQL and it maps the link table the same way the SQL schema has it when creating one. In other words LINQ to SQL isn’t smart about many to many mappings… >>> More
