In Visual Web Developer 2010, I'm trying to implement the extension to EntityDataSource described on this page that enables Insert() to be used as a method:
I get a compile error "CS0246: The type or namespace name 'EntityDataSource' could not be found (are you missing a using directive or an assembly reference?)"
I originally created the class as provided on this page:
No difference between the 2 (except the 1st link's version actually gets VWD to recognize the EntityDataSourceExtentions
class name as something - color codes it in blue-green.)
I should be using .NET 4.0.
