Remarks

Enumerating the collection in C# or Microsoft Visual Basic

A ColumnDefinitionCollection is enumerable, so you can use language-specific syntax such as foreach in C# to enumerate the items in the collection. The compiler does the type-casting for you and you won't need to cast to IEnumerable<ColumnDefinition> explicitly. If you do need to cast explicitly, for example if you want to call GetEnumerator, cast to IEnumerable with a ColumnDefinition constraint.
