C# vs VB.NET - Handling of null Structures

Question

I ran across this and was wondering if someone could explain why this works in VB.NET when I would expect it should fail, just like it does in C#

//The C# Version  struct Person {     public string name; } ... Person someone = null; //Nope! Can't do that!! Person? someoneElse = null; //No problem, just like expected 

But then in VB.NET...

Structure Person     Public name As String End Structure ... Dim someone As Person = Nothing 'Wha? this is okay? 

Is Nothing not the same as null (Nothing != null - LOL?), or is this just different ways of handling the same situation between the two languages?

Why or what is handled differently between the two that makes this okay in one, but not the other?

[Update]

Given some of the comments, I messed with this a bit more... it seems as if you actually have to use Nullable if you want to allow something to be null in VB.NET... so for example...

'This is false - It is still a person' Dim someone As Person = Nothing Dim isSomeoneNull As Boolean = someone.Equals(Nothing) 'false'  'This is true - the result is actually nullable now' Dim someoneElse As Nullable(Of Person) = Nothing Dim isSomeoneElseNull As Boolean = someoneElse.Equals(Nothing) 'true' 

Too weird...

If I remember correctly, 'Nothing' in VB means "the default value". For a value type, that's the default value, for a reference type, that would be null. Thus, assigning nothing to a struct, is no problem at all.
