Agreed. The framework incorporates some really great ideas and then falls flat in the implementation.
My biggest complaint (vs WinForm) is that the design UI completely sucks by comparison. In VS, with WinForm, everything is drag-and-drop / point-and-click. With WPF, I need to constantly resort to editing the XML. There is no reason it needs to be this way. They really need to either get a better UI team or give the team they already have time to fix it.
The other problem is the (effective) lack of immediate-mode graphics. I understand that for line-of-business apps this makes perfect sense. However, they should support a fall-back for graphic intensive applications. Try drawing and re-drawing a few thousand lines. Performance is fine in WinForm, but its frustratingly slow in WPF...even when you take advantage of all the WPF performance tweaks.
To solve this performance issue, we're left playing with 3rd party work-arounds...using writeable bitmaps. They work great. This means there is absolutely no reason, other than arrogance, that MS can't incorporate some of these concepts into WPF...in a better supported/more seamless fashion.
Also, provide better support for WinForm-style docking. Yes, I understand the other layouts are far more flexible and worth learning. I took the time. I still find them less intuitive. So, why punish WinForm developers making the transition? Keep the cool new layouts and add better support for docking layouts as well.
As it stands now, for me, WPF is an interesting toy for occasional play. I use it when I want some really flexible layouts...in line-of-business apps. Or, when a customer requests it. Or, when I play with UWP. Otherwise, I still use WinForm.
Its a real shame. I'd prefer to move full time to WPF, to ease the wear-and-tear switching back and forth causes on my poor brain. Come on MS...finish what you started!

XAML - I was full time in WPF and have never used drag and drop to get controls on a view  I had forgotten how easy winforms UI layout is. Thankfully I have never been into graphics, purely LOB work and I still run up against performance issues.

I've never used the UI designer, and do everything in XAML. Even Blend still scares the hell out of me to this day, and I'm a proficient WPF/XAML developer.
Writing XAML is no different to a web developer writing HTML - nobody uses drag'n'drop interfaces on that platform. Admittedly it's easier to see your changes by just pressing F5 in the open browser window, rather than have to run the app...

I haven't done anything in WPF for a while so I'm not sure if it works the same there, but while starting my 1st UWP app a few months ago I discovered that I could live edit the xaml while the app was running and have UI changes show up immediately in the app. On the plus side, no need for that pesky Alt-F-S, Alt-Tab, F5 to see changes; on the minus at times VS would interrupt the live editing to complain that a half typed bit of markup was generating a parse error.

I'm currently working on a graphics intensive application as well. Redrawing using WPF took about 7 seconds. We're currently using a SharpDX based renderer instead and when we need to update ALL the primitives and redraw it takes about 25ms.
WPF is based on Dx9(and needs to be updated to 12 tbh) so it shouldn't need to be this freaking slow!

Yeah, there is no reason it should be soooo painfully slow. Its significantly worse than any other presentation framework I've used. The excuse that its retained-mode vs immediate-mode doesn't really cut it.
It does not seem to be a DX issue. I've written code directly accessing older versions of DX...without similar performance problems. Somebody at MS needs to meter the WPF code and find its major malfunction.
Instead, all you see on the boards are apologists telling everyone they're simply "doing it wrong". This advice isn't entirely incorrect...people really do some dumb stuff.
However, this advice doesn't explain away all of WPF's performance problems. They're very real...and not going away until someone at MS fixes them. Regrettably, there seems to be absolutely zero movement on that front.

"Quote: The framework incorporates some really great ideas and then falls flat in the implementation.
I agree, to some extent. WPF uses the GPU instead of the CPU as WinForms does so rendering should be faster. But, in my case, I started with WinForms and before that MFC. Drag and dropping the controls was much easier and I spent less time on coding my window and more time on my application. There is a lot techniques you can do in WPF that you cannot do in WinForms to make a flashy presentation with great graphics, but WinForms is good for basic applications. I have found that I can get flashy usable controls from 3rd parties like Infragistics.
To me, drag and drop is much easier whereas, in the project I'm currently working on, WPF is the workhorse for us, since we keep adding more and more to the controls and sub-controls. Xaml allows us to finely control what we show. If we were to do it programmatically in C#, then it would be similar to QT.

Is it possible to tie HTML and CSS to compiled C# (instead of JavaScript)? To me, it seems that HTML is much more understandable that Xaml.

No!
C# does not run on your browser, only JS does.
C# requires the .NET framework, which is pretty huge (and doesn't work on iOS for example).

We tried it, but none of our developers really liked it, also judging from the lack of posts on CodeProject it does not seem very popular ...
|

It is actually very unpopular... My problem that extensions are using it by default, and the only other option is moving to WinForms... And even that is too easy...

I liked WPF when I used to work with it - you can make some really nice looking apps.

Granted - I saw some very nice looking ones...
But! If you put a DataGrid on a form and bind it to some data, plus add some buttons to each row (template)... It looks awful...

Ah thinking like a web developer, I cannot remember when I last had buttons on each row. My VM knows precisely what row is selected so all I need is the action directive, also double click is your friend.

Yes, the default look isn't very nice - it takes a bit of effort to style the app, but webpages are like that as well. You can get WPF themes or third part controls that look nice out of the box.

...if you're willing to allocate the resources to do it. Otherwise WPF apps can be made to look every bit as ugly as WinForms-based apps.
If your focus is not on the UI, then WPF adds a lot of cost (in terms of learning overhead) with very little return, IMO.

Because they decided instead to focus on an inane XML syntax instead that requires, among other things, custom instantiators instead of a simple parser and is almost (if not completely) impossible to express and correctly render in a designer, requiring you to hand code the XML, which when I wrote my articles on MyXaml, everyone screeched about how nobody would want to hand-code XML to design a UI, but when Microsoft put out WPF, that's what everyone was forced to do and even seemed to enjoy doing. Um.. end rant?
Oh, and because Microsoft likes to leave the professional UI design to third parties.

I am an old fossil — when I started there was no such thing as a graphics interface. Input was either punched cards, magnetic tape or an IBM Selectric or ASR 33 console. I definitely prefer XAML to drag-and-drop. It is much easier to write parameters to modify a control than to have to open a property window. Extending a WinForms property window? Not trivial. Adding a parameter to an XAML control, by way of contrast, is almost effortless!
I LIKE WPF!! I just wish it had better error detection at coding time.

Why do you need to write an extension in the first place? . There are third party grid components like xceed that can make life easier...anyway..
