Why can't c# use inline anonymous lambdas or delegates? [duplicate]

Lambdas in C# do not have types, until they are used in a context that casts them to a delegate or Expression type. That's why you can't say

var x = () => "some lambda";

It seems to work if you give it a type cast:

String s = ((Func<String>) (() => "hello inline lambda"))();

Is it useless? Not entirely. Take the below:

String s;
{
    Object o = MightBeNull();
    s = o == null ? "Default value" : o.ToString();
}

Now consider this:

String S = ((Func<Object,String>)(o => o == null ? "Default value" : o.ToString())
    )(MightBeNull());

It's a little ugly, but it is compact.
