I've made a suggestion in LadyBug regarding Typed DataSets in Visual Studio 2005. It might just be too late for this, though, but at least it's in the system.
Problem Statement: It seems as if there is no regard for the new features of .NET 2.0 in the creation of Typed DataSets.
Methods like Find, FindAll, ForEach, etc. exist in the generic list and should be implemented per typed DataTable.
I'm certain there are many more useful methods that can benefit from the new features in 2.0.
Proposed Solution: Examples:
public DataTable1Row[] FindAll(Predicate match);
public DataTable1Row Find(Predicate match);
