Sometimes VS and .NET is a PITA. But you know that.
I needed to have an Azure web app (Framework 4.7.2) log to app insights, so I installed the various AI packages and MS extensions dependency injection abstractions package. I ensure the abstractions DLL shows up in my references, I have a 'using' reference to it, and all that looks good. But VS is telling me the type and namespace can't be found for the ServiceCollection object, although it sees the bloody IServiceCollection interface. The same packages and the same code works in a console app on the same framework version.
So the big question is, if I retire now, can I live off a reduced SS check and my current 401K and savings for the next 20+ years?

Did you include the assembly as a reference?

No 401k in Europe. Ask an American.

It shows up in my references, so I assume it's there. I tried to find it in the Reference Manager to add it manually, just in case, but it isn't there. Not sure that's a problem since it isn't in the Manager in the console app, either, and it works fine.
I could retire now if I could talk my wife into moving to Arequipa, Peru. And if we could speak Spanish.

Then why are we talking references my man?
You don't need Spanish in Peru (though it helps).

It was an assumption, sorry.

You need a reference to that DLL, as far as I can guess now.

Yep, or the right DLL, which is another rabbit hole I can't find the bottom of.

Even though I can't, I would given the option. Go live near the coast and be happy?

I enjoy the ocean, but I prefer mountains, or at least very tall hills and ridges, buried in trees, flowing with rivers to kayak and caves to explore. That's my retirement plans.

Thanks, that got me closer. I removed what I had and installed the Microsoft.Extensions.DependencyInjection package, which also installed the Abstractions package, using the same version as the console app. It now recognizes some version of the ServiceCollection, but not the version with an IServiceCollection that contains the definition for AddLogging and AddApplicationInsightsTelemetryWorkerService. And yet both the web app and console apps are using the same version of those packages, as far as I can tell, and those methods are defined in the console's version.

It will be the right ServiceCollection; it just looks like you're missing some other references.
AddLogging is an extension method defined in the Microsoft.Extensions.Logging NuGet package.AddApplicationInsightsTelemetryWorkerService is an extension method defined in the Microsoft.ApplicationInsights.WorkerService NuGet package.

Thank you. I owe you a beer. Or three.
The question I (and probably you) have now is, why couldn't I find that answer myself? My google-fu is normally black belt level.
But you have to admit the situation is complicated, even bizarre. IServiceCollection is in the Microsoft.Extensions.DependencyInjection namespace, but the methods attached to an object instantiated from that interface are in two other namespaces. I mean, what the actual elephant?

That part actually makes sense: the extension methods are defined in the assemblies they're used for. Otherwise, all of the classes to configure eg: logging would need to be included in the DI assembly, which would be an absolute mess. 
For the Microsoft extensions I've seen, the class where the extension methods are defined is usually deliberately added to the Microsoft.Extensions.DependencyInjection namespace, even though that's not the correct namespace for the assembly. That way, you don't have to add extra using statements to your code to configure the services; you just need a reference to the assembly.

My rig bombed out, and until I could get a cheap WinTel spare (while I look for my dream gamer rig), I was stuck surfing the 'net with my Android phone. Oh my, what a horrific experience, between all the junk ads and not being to use Firefox's Bypass Paywalls add-on. I am considering getting an Android pad, which would be for me just for use when I'm in public transport or eating at a restaurant, etc., but if with Android I will be stuck with this rotten experience, I'll just stay with my dinosaur era phone using Opera Mini (which is so old that ads are too sophisticated, and which isn't a problem since I am only interested in the text).
Any ideas that do not involve paying through the nose for an Apple?

A gross experience, was it?

Wrong
It is more along the lines of "gross income" or "gross taxes". The whole, with nothing taken away. As opposed to the "net income". You get the whole web page with all the ads, nothing taken away. swampwiz didn't want the gross page, he wanted to surf the net - that is, with the ads removed. And apparently, he thinks web pages with all the ads are rather gross.

This was a big problem for me too. I finally solved it by installing a VPN server at home (we have Gigabit fibre here) and a pi-hole DNS cleaner. The VPN is SoftEtherNet which is really simple to set up and doesn't need any client software. While I'm out and about I just fire up the VPN on the phone and get virtually ad-free browsing just like when I'm at home.

I use MS-Edge on my Android phone and have very little advertisement or spam in my Android browsing sessions.

I was able to download the Firefox App, and from there add the necessary addons. There is hope for the world.

Pi-hole. Set it up as your gateway going out to the internet, and suddenly every device on your network benefits from ad blocking performed in a single place, before any traffic can reach any other device.
I have a VM with 512MB running Debian dedicated for it. I could probably drop the memory even further if I cared to even look how much it's using on average. That would be a good job to give a Raspberry Pi.

So some time ago, I was really struggling trying to get my optimized SPI bus code working on an ESP32.
It was confounding me. I was using a reference implementation and I could have sworn I copied the functionality (but not the code) precisely. I even verified as much as I could with serial port spew.
Well after banging on it a month or two later, it turns out there wasn't a problem with it at all - I was simply selecting the wrong bus when I initialized the driver from my demo code!
I love this. Now I have a bunch of code in front of me I can actually work on. GFX is getting another major update. Woo!
