Just my $.02:
WinForms are really easy. And I mean, REALLY easy, I've enjoyed using them for years.
The click for me, when going to WPF, is: 4K monitors. If your resolution is high-res (such as, for 4K), WinForms are taking a really big fall. About close to 2 years ago, I got a laptop with 4K resolution. At this point, things starting to go downfall. What you see in the VS designer, is not what you will see visually. Some of the controls you create will look incredibly messy. The AutoScaleMode : if you go with Font, it will look horrible. If you go with Dpi, sometimes it's decent, sometimes not - what I've found is that most of the time, as long as I keep the form/control under 1900x1080, it's ok; and as a side-note, never go with None.
Now, add to that the Anchor property - which I used heavily to properly align controls. It seldom works on high resolution monitors.
What you end up is pretty much "try to see if it works". And "if" it works, you need to then test at other resolutions. So, long story short, as monitors get higher and higher res, WinForms is losing ground.
Now, onto WPF - really steep learning curve, but the results can be amazing. A lot of things will once again be "trial and error" at first, but once you get the hang of it, and if you have some pretty fancy UI in mind, WPF can definitely help you there. That, and Resharper

I suffered this problem with my winforms when the new higher resolution and wide screens came out.

Thanks 
One other issue I just remembered - sometimes, when lots (I mean, LOTS) of controls on a dialog/usercontrol, the VS2013 designer crashes a lot of times - so, editing the dialog/usercontrol is a huuge pain. I would have expected this to be solved later on (VS2017), but turns out this is not the case.
Best,
John

Yeah, I've run into this problem also in VStudio 2017 and didn't even have a large number of controls.

As I get older all my skill declines.. 
For example after reading your message a few times I fail to see your point.. is it a question? (about what?) a statement? (for whom?)...
Glad you play with XAML anyway. XAML is great!
Other than that WPF is great! Ever heard of Visual Studio? It's a WPF application ya know!
But not many people write desktop application these days, that's why WPF is kind of neglected...

That is good...I know I should feel like that is good.
But when you are spoiled by WinForms development and you drag and drop the control and it "Just works" it's difficult to be excited by that.

I work in WinForms with a team that requires ease of maintenance over innovation. Being a 20+ yr. programmer, I have learned that getting deeper into whatever you are using generates more functionality than any shiny new tech you learn from scratch. That doesn't mean that a better way of building things is ignored, just that you learn to sift value gained vs effort spent.

Well its up to you..besides there are a number of third party WPF controls available in the
market if you don't have the time to do the development esp if you are building a LOB application.

I have used WPF outside on my personal projects and as has been said before WPF makes the simple complicated and the complicated simple.
My experience is that it's a bit like doing web development - it can be a real PITA but when done right gives you something nice to look at... and that's pretty much what it comes down to - you can create 'nice' custom controls and it encourages loose coupling of the data and the UI.

That's a perfect explanation of the situation.
That's a perfect quote for everything Microsoft is doing now, it seems.

Come to think of it... I think you have a good point
What I describe does indeed pervade most of what Microsoft does and in fact most of IT nowadays.
What I see happening where I work is that the young-uns actually admit that the only reason they introduce new frameworks into the business is to improve their cv.

Yep. That nails it.

I'm not well versed in UWA matters but in WPF using a behavior would be one route you could take. Maybe not exactly what you're trying to achieve, but when working on a SignalR-WPF chat application I needed new items added to an ItemsControl to scroll into view, which is not the default behavior of the ItemsControl. I wrote a behavior to achieve this, which you can look at here: SignalChat: WPF & SignalR Chat Application.

That's a very nice article and a nice explanation of that behavior.
I will look at that more closely.
I was wondering if it would be a behavior which I find interesting since it feels like this simple thing takes a bit more processing power -- observing an event, instead of the thing just getting set and forgetting about it.
Thanks very much.

We started to work with WPF and MVVM years ago and I am very astonished that people still use WinForms. WPF/MVVM really does everything we need (for our standard product for company users). And I never found it difficult to get other developers' advice and examples for WPF.
We also have some UPW apps in the store, but I cannot find companies working with them.
Btw, I understood, that UWP is based on .Net Core and therefore will survive, when the Win32 kernel will die.

I'd rather deal with the quirks of HTML than WPF, which I won't tell you what it reminds me of every time I try to use it. Think Alabama voters and why they don't vote Democratic (usually.)

I moved over to WPF a number of years ago simply because it had been touted as the technology to replace WinForms.
To me WPF biggest advantage is that you can program it in similar style to that of an ASP.NET WebForms application. However, this is about its only real big advantage.
WPF documentation is notoriously fragmented, and in some cases just downright bad.
The complexity in developing a nice interface with WPF is terrible. And like ASP.NET MVC, forces developers to take on more complexity than is actually needed.
Having to rework templates for a single control simply to have it work in a manner consistent with how you may want it to work with your application is beyond ridiculous. And the time-worn excuse that WPF is designed to be highly flexible as a result, is pathetic. On average, how many developers really require such flexibility. I have never seen a need for it in my career.
The problem is that Microsoft is still trying to set trends instead of maintaining mature platforms that have made it very easy for developers to build and implement applications. As a result, you have gotten such implementations such as ASP.NET MVC, WPF (with all the complexity), and LocalDB (supposedly to replace SQL Server CE).
Though I believe that WPF would have seen many more developers gravitate towards it had Microsoft streamlined its interface design with less complexity, they don't seem to be interested in refining this development environment. The form designer is still terrible in that you cannot accurately gauge where anything will actually show up as with the WinForms designer.
My complaint about a lot of this can be encapsulated around LocalDB. Though an excellent refinement for SQL Server Express it can hardly be seen as a real replacement for SQL Server CE, probably the finest desktop database ever produced to date.
SQL Server CE served a very specific purpose for those developers concentrating on the desktop. And as of a recent Microsoft survey (I believe), 46% of all development, despite all the hype is still for the desktop. With a few refinements, SQL Server CE would have been a snap to deploy and would have remained the desktop database of choice for a long time.
Instead, with the new directions of Microsoft under Nadella, who like all technology idiots with a "vision", he is enamored with cloud computing, which was a major factor in SQL Server CE's demise. Instead of offering both, SQL Server CE is simply removed from the product lineup. At the very least it could have been Open Sourced to a third party.
True, LocalDB can be used with desktop applications but it is a far larger implementation. To avoid user intervention during an installation process one has to set up their installation with a silent install. If you want to control any of the features of LocalDB from your application (beyond data access) you have to use a "Process.Start" method to run the "SqlLocalDB" utility to create instances, databases and the whatnot.
The idea of on-demand servicing, where LocaldDB remains dormant until a call is made for a request is rather ridiculous, considering that it will then only stay active for several minutes at a time.
With this milieu, Microsoft now claims this is a great database for developers and desktop applications. I would like to know how, when SQL Server Express is a snap to set up and SQL Server CE avoided a lot of the LocalDB issues.
Thinking like this is why WPF is a great way to program but a painful implementation to deal with...

These are all the exact things I was thinking as I wrote my original post.
The designer where you have to see XAML and Design View takes up so much space, controls are often invisible --- no borders or anything show up.
Documentation is extremely fragmented!!
All great points and reasons that XAML dev never really took off like it should've.
And, yes, desktop development is still a huge part of ongoing development in the Enterprise (where most money is probably dedicated to development too) and yet everyone is so (supposedly) focused on web apps, cloud, etc.
It doesn't add up.
Thanks for a great post.

I admit the form designer in WPF sucks that way. I happen to love setting up grids in xaml to get everything precisely where I want it without having to drag and drop. I may be weird...

Feature for feature, WPF has more to offer than Windows Forms; except maybe for the "Open / save", etc. common dialogs.
You fail to find an answer to you "obvious" question, and therefor discount the entire platform.
Funny thing is, I'm currently looking at a panel which has multiple ListViews with GridViews inside a WrapPanel, and ALL the ListViews are showing the "items that lost focus" as having a "different hilite" than the ones that were not selected. Looking at other implementations, they ALL show the item that "lost focus".
And I did "nothing" to activate that functionality. Maybe that's why there are no "articles".
Default behaviour out-of-the-box (if you don't override it; like one of the "system colors").

Yeah, a lot of developers forget the wonderful experience that is writing a <control value="Bind"> and then everything just works with no edge cases, allowing you to expand on the complex stuff. That's how you get sh*t done.
