How can I create a singleton IEnumerable?

Question

Does C# offer some nice method to cast a single entity of type T to IEnumerable?

The only way I can think of is something like:

Answer 1

var entity = new T();
var singleton = Enumerable.Repeat(entity, 1);

(Although I'd probably just do var singleton = new[] { entity }; in most situations, especially if it was only for private use.)
