Type inference from L-values and return types

[ekolis]

If I have this code:

IEnumerable<int> nums = Enumerable.Empty();

I get an error saying that the type parameter of Empty can't be inferred. But why can't it? I'm assigning to an IEnumerable<int>; couldn't the type parameter thus be inferred to be int?

The same goes for return types:

public static IEnumerable<int> CreateEmptyList() => Enumerable.Empty();
