VB.NET has no direct equivalent. For what it's worth, neither does C#.

It depends on what you want to use it for... If it is for P/Invoke, then
yes, you can define something like a Union using marshalling attributes. But,
if it is just for your own use in managed code - then not really. You
could probably write a class to fake it... Using a byte array
internally to store the data.

Yes, this can be done using the 'FieldOffset' attribute:
