I have seen similar questions to this, but they involve different types so I think this is a new question.

Consider the following code:

public void Test(bool value)
{
    // The following line provokes a compiler error:
    // "Type of conditional expression cannot be determined because there is 
    // no implicit conversion between 'method group' and 'method group".

    Func<bool> test = value ? F : F;
}

public bool F()
{
    return false;
}

Now, according to the C# 3.0 Standard,

The second and third operands of the ?: operator control the type of the conditional expression. Let X and Y be the types of the second and third operands. Then,

If X and Y are the same type, then this is the type of the conditional Otherwise, if an implicit conversion (§6.1) exists from X to Y, but not from Y to X, then Y is the type of the conditional expression. Otherwise, if an implicit conversion (§6.1) exists from Y to X, but not from X to Y, then X is the type of the conditional expression. Otherwise, no expression type can be determined, and a compile-time error occurs.

It seems to me that in my sample code, X and Y must be of the same type, since they are the selfsame entity, Func. So why does it not compile?
