string str = string.Empty is the proper and more efficient way.

Thanks,
Well, it's not more efficient as they are both string literals, but the
code more closely resembles the intention.
If you always use string.Empty when you want an empty string, you know
that when you find "" in your code there is something that you
accidentally removed or something that you forgot to put there.

I've been told that string.Empty does not require any user memory, and
every time you reference "" you use a little bit more user memory to
store the literal.

You've been told wrong then. At worst, all uses of the explicit literal
"" will use the same object, due to string pooling (I think in C# they
call it interning...sam e thing).
Personally I find "" more concise, just as expressive (if not more so) as
String.Empty, and I've never in decades of programming accidently deleted
the entire contents of a string literal. So for me, "" suits my needs
just fine.

Evenif the references are in difference classes in the same project?

Although I prefer the latter of the two, I don't think it makes much
difference.
Personally, I would use string.Length == 0.

Yes. The pooling isn't restricted to per-class.

Even different classes residing in different assemblies loaded in
different app domains.

The classic reason for using names instead of values is
that if you want to change the value, then you only need
to change it one place.
Very good reason. But it does not apply here. You will
never want to change the value of the empty string.
And "" is actually easier to read, so I will consider that
the proper way.
You could forget to put something within the "" but you could
also forget to write something instead of String.Empty - I can
not see the difference.

I am surprised to discover that c# automatically converts an integer to a
string when concatenating with the "+" operator. I thought c# was supposed
to be very strict about types. Doesn't it seem like c# is breaking its own
rules?
This works:
int b = 32;
string a = "ABC " + b;
Result: a = "ABC 32"

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
