It's one of those things where coding it is much easier than explaining it. I'll have to whip out my trusty graphviz and throw together some visual diagrams for the article. I think that's where half the work would be.
The other half is cooking up a contrived enough example that's small enough to show how it works without being overwhelming - harder than it sounds since the main use of it is to *avoid* stressing the garbage collector, so it's something where it has to be used a lot to see a difference.
Although I can think of a "hack" using GC.Collect maybe that will force its impact to be felt. I'll have to test.
So much work for something that probably wouldn't make beyond a tip and trick, but I suppose it's helpful to know.
I ran into it clear back in the bad old days of .NET when the GC was choking on something i built and this was before I really understood the principles behind garbage collected environments. Circular references are Bad(TM). The GC will eventually figure them out (i think) if they *both* get orphaned from everything else but it's extra work and i'd have to check to be sure it did that- which i think it does, but again, extra GC bookkeeping under the hood. You really don't want to force that.
By then I was already using Boehm's garbage collector in my C++ ISAPI code (for speed - no string heap fragmentation and i'm a bastard about server performance) but since it was just for strings, and not object models circular references were never an issue.
When I was growin' up, I was the smartest kid I knew. Maybe that was just because I didn't know that many kids. All I know is now I feel the opposite.

what you describe could be the basis of an interesting article.

foo("bar");
does this refer to an invocation of the method foo? or an invocation of the delegate instance referred to by the variable or argument foo?
*headdesk*
C# is massively ambiguous without having type information, so now I get to write a visitor to "patch up" the code dom with type information. So basically i always create these expressions as delegate invocations, but then i have to go back through later and find types, so I can change the right ones to method invocations instead.
I know C family languages require type information to parse (which is unfortunate) but C# takes it to another level. In for a penny, in for a pound I guess.

Neither: it means a VB programmer wants to access an array element and forgot where he was.

lol, i'm glad my c# compiler doesn't see it that way. =)

I don't see it that way and I am a VB.NET programmer but also fluent in C#.
It is amazing how many people really view C# as some completely different type of animal than that of VB.NET...
To me, the line of code was calling the method, "foo", with a string parameter...

He is referring to old classic VB, which of course any public function in Module can be called from anywhere.

#define then {
#define endif }
lets make C really basic so anyone can do it
Edit: more complete
#define IF if (
#define THEN ) {
#define ELSE } else {
#define ENDIF }
this internet has become nothing but fake news.
... time to fix it, time to get back to the fax!
