Are there any good workarounds for FxCop warning CA1006?

Question

I am having trouble with FxCop warning CA1006, Microsoft.Design \"DoNotNestGenericTypesInMemberSignatures\". Specifically, I am designing a ReportCollection

Answer 1

I agree that you can ignore the CA1006 warning in the case of

Func>

Also you can simplify your code by using delegates and avoid the CA1006:

public delegate IEnumerable ChildrenDel( T parent);

// was: GetDescendants( this T item, Func< T, IEnumerable< T > > children )

public static IEnumerable< T > GetDescendants( this T item, ChildrenDel children )
{
    var stack = new Stack< T >();
    do {
        children( item ).ForEach( stack.Push );

        if( stack.Count == 0 )
            break;

        item = stack.Pop();

        yield return item;
    } while( true );
}
