I may be thinking of another incident where researchers just tried the default MongoDB port on thousands of servers and found that for many of those servers the port was open and the database was exposed.

Quote: MongoDB is a general purpose, document-based, distributed database built for modern application developers and for the cloud era.
However, they also say:
Quote: No database makes you more productive.
So I guess simple text files are the future.

MongoDB - where GUIDs are displayed in the wrong order just to punish you.
2/5 would not use again.

Because 1.x existed prior to generics we have issues of legacy object models not implementing IList<T> and instead simply exposing hard typed indexer properties.
Normally, you'd just get the generic parameters of the generic IEnumerable<T> interface, but because some object trees were created prior to 2.0 - like the CodeDOM they don't have them.
This makes determining the element type of a typed list extremely difficult. The problem is that your alternative is the indexer property which isn't a member of a hard interface, so you have to select the appropriate indexer property from the properties on that type. There might be this[string name] in there too, for example. There is no contract however, so there are no guarantees. This isn't especially robust.
Which means, the obvious solution is to first try to get it using the generic interfaces, and if they aren't available, then we fall back to the less robust method above.
This is not ideal, and it requires maybe a page of code to handle all the scenarios.
Microsoft didn't put generics into 1.x I think because of time constraints, and if so they should have waited, IMO.
Edit: For anyone interested I just posted a tip that solves this problem. How To Get A Collection Element Type Using Reflection in C#[^]

I agree.
V1 should never have seen the light of day.
And sub-teams working on different areas should have communicated, and there should have been a core team to determine commonalities.
I mean, seriously!? 
public ArgumentException (string message, string paramName);
public ArgumentOutOfRangeException (string paramName, string message);
public ArgumentNullException (string paramName, string message);

Do you mean there are three argument Exceptions (which I can understand) or that message and paramName are switched in two of them?

I suspect option 2.

1.x was just "beta" to play around with, it was never intended for production code, but *hands up* the company I worked for at the time did indeed use it in production. We used sockets a fair bit to communication with UNIX systems and also with banking applications, and .net had socket classes built in so we were keen to migrate to it ASAP.

At a previous employer I maintained a .net 1.1 winform app from 05-08. (Other people wrote the initial version in 04 before I started.) We couldn't upgrade to a newer version initially because the customer still had NT4 boxes at some sites; which couldn't run .net 2.0. 
On the plus side the beige NT4 tower stuck in the back corner of my cube gathering dust was my justification for having N+1 monitors for years. (With the +1 spending 99% of its time connected to my main computer.)

Hopefully it will be all fixed in .net5! 
Exception up = new Exception("Something is really wrong.");
throw up;

There's little to fix. The problem I think, is backward compatibility. I mean, I suppose they could rewrite the CodeDOM in a new System assembly but I think they'd be more likely to retire it, if anything.

I like the CodeDOM and use it a lot, since it is built in.
Exception up = new Exception("Something is really wrong.");
throw up;

I use it quite a bit myself. At the risk of advertising here you might be interested in my project:
CodeDOM Go Kit: The CodeDOM is Dead, Long Live the CodeDOM[^]
It's quite powerful. It even allows you to parse a C# subset into the CodeDOM so you can construct CodeDOM graphs using C# code, which saves a lot of typing. It allows you to query a CodeDOM tree, and even can perform complex operations on CodeDOM trees like reflection and method selection.

I'm still waiting for, "the framework which is to come after .net" .

.net++
That'd be .neu (new in German)!

.net core is opensource. Feel free to do MS's job for them (because we all know they won't ) and submit a PR.
