Func<T>() vs Func<T>.Invoke()

I'm curious about the differences between calling a Func directly vs using Invoke() on it. Is there a difference ? Is the first, syntactical sugar, and calls Invoke() underneath anyway ?

public T DoWork<T>(Func<T> method)
{
    return (T)method.Invoke();
}

vs

public T DoWork<T>(Func<T> method)
{
    return (T)method();
}

Or am I on the wrong track entirely :) Thanks.

There's no difference at all. The second is just a shorthand for Invoke, provided by the compiler. They compile to the same IL.
