Windows Forms has always seemed to me to be a .NET wrapper around ye olde message pump and GDI.
Back in 2008 we started a major new product development. Up to that time our UI's were implemented in C++ and MFC. As I saw it, we had three options: C++/MFC, WinForms/C#, and WPF/C#. One of the pain points in C++/MFC was how laborious it was to make a UI adapt to changing conditions, screen resolutions, and window sizes. WinForms didn't add anything appreciably new. WPF on the other hand assumed from the start that a UI should be adaptive. It also made commonplace UI elements (graphics on a button, for example) trivially easy.
We went with WPF/C#, and have only had one hiccup in the 13 years we've been working on this product. The WPF document and page navigation features were both unreliable and unbelievable memory hogs. Page navigation had incredible memory leaks; dozens of MB for the simplest pages.

The one WPF app I did (~4 years ago) the biggest problem we ran into was that complex pages took too long to initialize on slow systems[*], which we eventually worked around by writing a caching layer into the navigation so we only ever had to create them once; at the cost of higher memory consumption.
[*] This became an issue midway through the project. Initially the customer had given us a cheap/slow W10 tablet + dock to test with, but assured us the normal production hardware would be much better. 4 or 6 months in we got a copy of the main target hardware, and discovered the that kiosk they were using had the same 1.x ghz first generation in order Atom CPU, same paltry amount of ram, and similarly awful eMMC storage.  And the ~1s max load times we considered acceptable on my 15W laptop were 5-10s on the crappy atom; which was totally unacceptable. 😡

... a solution to problem that no one had in a overly complex way, it tried to be html for winforms, while it does show things in a beautiful way and on high dpi screens it just is not worth the effort, and is bloated.

I started .NET development using WinForms.
When WPF came around, I tried it over and over again but was struggling to use it.
Then one day it clicked and I never went back to WinForms again.
I really like WPF. It gives me the option to apply the look and feel I want, without having to buy expensive frameworks.
Agreed, it takes a lot more time to set things up. Creating styles and themes, but when that is done, you re-use them for every project.
Visual Studio is also improving the WPF experience by adding more and more tooling.
For me, never WinForms again.

wow, where to start? Windows Forms with .Net is NOT as bad as everyone thinks. What's bad about Windows Forms is how people use it. What happens is someone with ZERO programming experience builds a business application on the platform and crams all their code in the code-behind class. They put the business logic, the persistence logic, and any logging and metrics all in that one class behind the form. They also only have ONE form for every part of the application. They don't make sub-forms or sub-controls, it's all one huge monolithic beast. They also don't apply any patterns to aid in decoupling any cross-cutting concerns, namely, using MVP to separate the form from any logic or using some message bus pattern for event handling across the app. Yeah, Windows Forms are horrible because the apps built on them are horribly done. If done properly, Windows Forms can be a quick and clean way to build internal tools for your business. See: Windows Forms Best Practices | Pluralsight[^]

I found VB4-6, MFC, and WinForms a lot easier to get to grips with as there's so much less 'hidden' stuff going on. WPF/XAML is really slick & powerful but for someone like me who is only a part-time GUI developer and spends a lot more time doing non-GUI development, it's hard to dabble in.
If I use it consistently for a while I start feeling more comfortable but then after a few months away I come back and feel clumsy again -- especially working on a codebase with contributions from a lot of people who are also nowhere near being WPF experts.
We also find skilled WPF programmers difficult to find & hire.

Don't get me wrong: Developers need to earn, and ad supported software is a way to go - provided they don't get too "greedy" I'll either go with it, or pay for "no ads". If they get too greedy - and I've met games where you can play for 5 seconds, then have to watch two 30 second ads before the next "round" - then I'll delete them, simple as that.
No, I'm talking about the thirty second ads that get to 25 seconds or so, and open the play store automatically so you can just install the app. And the time you spend closing that and getting back to the original ad doesn't count - the timer "paused" while it opened and doesn't restart until you are back with the ad. so for a "30 second ad" they get extra exposure.
Does this encourage me to install the product? Not on your Nellie ...

Not only Android adverts... The industry as a whole has got a bit too far with adverts.

Yeah.
But the problem is partially (at least 50%) caused by the majority of the users too. Before the producers (mostly) had to convince you with the quality of their product and you bought it. Now the main revenue come with built-in publicity or data slurping / shopping it to third parties, not with the sells themselves.
And as long as the 90% of the population continue consuming this system, it won't change (at least not in the good direction).
As it has been said a lot of times... if something is free, you are the product.
M.D.V. 
If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?

And a lot of that is because the product is generally so poor that if you did "try before you buy" they won't sell any ...

Oh so true. It's the same thing with radio adverts. They have begun repeating the phone numbers not twice, but three or four times. It's as if they think they can force you to call.

That's still a thing?
Seriously, I never tune in, but when I'm riding in a car with someone who listens to commercial radio - it horrifying. Is there not any cookie-cutter radio station anymore, or something NOT owned by iheartradio?
It's all about follow us, like us, subscribe...yeah, to get even more of that crap - why would I want to put myself through any of that?

I warmly recommend radioparadise dot com
100% ad free (voluntary listener supported) and a pretty awesome music mix.

I never said I was looking for ad-free alternatives. I was lamenting the state of commercial radio - the kind I'm stuck listening to when I'm sitting as a passenger in someone else's car.

Like you, I don't mind advertising-supported development. I do appreciate the option to purchase an ad-free version, although I don't like the subscription model to maintain "ad-free".
I tried a music player once on my phone that was really nice. Clean layout, handled all of my music intelligently. The ads were a little intrusive, so I spent the $19.95 to get it ad-free. At the time, this was a steep price for that sort of thing, but the program itself was pretty good.
Until the ad-free 'trial' ran out after 90 days. At that point, if I wanted to maintain ad-free use of the app, they wanted to charge me around $10 a month. For a ![Elephant | [mastadon]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/elephant.gif) ing music player.
No thank you, uninstall, and brief expletive-laden message to the developer that if I ever saw another charge on my credit card from them they'd be reported to law enforcement for fraud. Miserable deceptive s.

The ad supported model is pretty good, when it's used right: to let us try before we buy while giving some reward to the developer while we make up our minds f it's worth the money...
There are good ones: for example OurGroceries - the ads weren't intrusive, but it is damn good. It's a shopping list - but it's server based, so if Herself notices the milk is low, she can add it to the list, and it appears on my phone, even if I'm in the supermarket at the time. And the tech support is "direct to the developer" who is really helpful. I bought it twice - once on my account, once on Herself's because it's worth it to me.
But ... there are a lot of total ripoffs out there, and it's hard to spot which is which sometimes.

It's not just you. Showing me an advertisement is one thing. Loading another application and forcing me to visit a different site is quite another.

Celebrate the power of AND!
Both you and google ads are getting more annoying!!!!
If you can't laugh at yourself - ask me and I will do it for you.

I like to veg out to a mindless game, bubble shooters are a good choice but the ads were so intrusive I had to give them up for MS windows 7 games I managed to find. The last update from MS actually deleted the installed games, now that really annoyed me. Thankfully they were still in my download folder.

Given a number N, let P be the set of all the prime divisors of N. Now, let S be another set of all the divisors of N (including 1 and N). Let's define the term Prime Score of a prime divisor x as the number of elements in S which have x as a prime divisor. Output the product of prime scores of all the elements in P modulo 1000003.
For example, let N be 12. Set P will be {2, 3} and set S will be {1, 2, 3, 4, 6, 12}. Now, 2 is a prime divisor of 4 elements in S (2, 4, 6, 12) and 3 is a prime divisor of 3 elements in S (3, 6, 12). So, the prime scores of 2 and 3 would be 4 and 3. respectively. So. the output will be 4*3 mod 1000003 = 12 .

Two things:
1) This is the wrong place for such questions, as it explains at the top of the page.
2) While we are more than willing to help those that are stuck: that doesn't mean that we are here to do it all for you! We can't do all the work, you are either getting paid for this, or it's part of your grades and it wouldn't be at all fair for us to do it all for you.
So we need you to do the work, and we will help you when you get stuck. That doesn't mean we will give you a step by step solution you can hand in!
Start by explaining where you are at the moment, and what the next step in the process is. Then tell us what you have tried to get that next step working, and what happened when you did.
