You jump around way TOO much and I am not sure sometime where things are being added ... also shortening the typing, for say comment but there are others, throw off where we are. I have been spending more time rewinding than listening
You touch upon UML and Use Cases, which is excellent as code follows design. However I've never had to pause so much in a tutorial. You don't tell us what the shortcuts for autogenerating the code are, although I did figure out "ctor-tab-tab". When you did the constructors for the Exception and at least three were autogenerated, at that point I'm like "WTF?".
The thing is, this is not a tutorial on those kind of things. If you're wishing to learn MVVM is because you've already gone through a decent chunk of work related to C# and programming in general to be seeking improvement in the design-pattern area, which is far gone past the VS navigation/shortcut perks. I personally appreciate when the tutorial doesn't branch away from the topic explaining little details of everything, because when you're learning something new it's important to keep that momentum that makes you flow through new concepts and ideas efficiently, and I think that momentum is fragile and must be kept at all costs.
This was presented way too fast. Maybe this would be useful to people who already know the information and just need a refresher but for those who are trying to learn... forget it. I got some useful information out of this but I felt like I was missing a lot of context.
I am a new developer diving into WPF. I watched this tutorial from start to finish and found it extremely helpful. The speaker took great care in explaining each paragraph in the video, covering everything from building functions from scratch to refactoring and optimization. I highly recommend this video to developers venturing into WPF and utilizing the MVVM framework. It's definitely worth watching from beginning to end.
Stay away from this tutorial unless you are very good at C# development already. First 5 videos are very good for understanding basic MVVM concept but after that its complete mess for begginers. This guy is very skilled and clever and his backend is rather over complicated for functionality than simple for tutorial. Also there are no clear explanations and lot of references to different videos.
Hey I appreciate the feedback! I think your points are pretty realistic - this tutorial could be better. I hope people absorb the approach I take rather than copying the code, and then use that to influence their own MVVM style. I also blame WPF for being a tricky framework and sometimes needing unnecessarily clever solutions for things 😄 I think there is still a lot of value in this series, but I definitely want to re-think some things, listen to feedback, and create a better tutorial in the future!
Worse tutorial yet. The only people who could follow along at this break neck speed without detailed explanations probably don’t need this tutorial in the first place
Yes I need to go slower 😂 I have learned this over the years, especially from the feedback I've gotten on this tutorial. I'm hoping this is still valuable given the lack of WPF resources out there. Can always reduce playback speed or re-watch parts if it's too fast, although that is not ideal for viewers. I also hope people are more focused on the approach I take, and not the specific code I write. But I understand everyone learns differently! I really just need to own up to and create a slower WPF tutorial because I get a comment like this everyday on this series 😂
Thanks for the feedback Klondike! It is a bit too fast. I've secretly taken a break from recording new content for the past 3 months in order to work on pace, quality, etc. 👀
Hi, I'm struggling to switch multiple checkboxes turn on and off at once by selecting multiple checkboxes. I look at youtube, forms, etc. but it seems there's nobody with the answer. Do you know how to switch multiple checkboxes in WPF? I prefer to use the MVVM logic. Thanks in advance ;)
I have never seen a tutorial video so concise and so on point on any topic. You are my new favourite tutor. I`m baffled on all the stuff you went into, I`ll be returning to this video to get ideas when building models for any application. That was trully aweome.
@@SingletonSean Thank you, my best teacher, I learned a lot from you about MVVM. Thank you for your effort. I would like to be a member of the channel, but my subscribe icon does not appear, I am from Yemen, I do not know if you have already defined your audience, and I have another question: \\\ Do you have a lesson that explains Using all the package functions (MVVMEssentials) + Dependency injection as I explained in the Full Stack WPF MVVM series..?? ///... Thanks for your great effort .
Everywhere I look people say you need a framework for MVVM in .NET, but here you show that you really don't, what am I missing? Is it just the dependency injection capability that these people mean? Why use MVVM framework when you can not to?
I feel the same way! I think the big thing with the MVVM frameworks is navigation support, as well as DI like you mentioned. I'd have to try out a framework to really have an opinion though.
I'm thankful for the fact that you're sharing your knowledge with us, but if I may.. Lots of us would benefit from a more relaxed pace and not seeing you flip from one tab into another while you continue explaining. I'm saying this because I'm attempting to follow along with you and find myself not only pausing to keep up, but also having to rewind to actually grasp what you're saying. A steady pace for the same content you're already producing without jumping back and forth between classes to illustrate what you're trying to say would probably attract a lot more viewers. :)
Hi this might be a stupid question, but at around 5:50 I don't understand why we need to override the equals operator. Why can't we just use the normal Equals for the object? Thanks for the tutorial.
Yeah I have the same thought. I don't really understand why we're throwing away all the functionality that the method offers and narrowing it down to just what our usecase would be.

Ever heard the term' Dazzle them with brilliance or Baffle them with BS'. Slow it down if you really are trying to teach and not just SHOW OFF. The work is good but useless if the people trying to learn it spend more time rewinding then learning.
really cool presentation of WPF even if it is a little fast for me. Btw, one question it loook like a lot of logic is implemented at Model level. Why not having this logic in upper layer ?
First of all GREAT tutorial. Second, I was perusing some of the earlier comments to see if someone had pointed out an error in the Conflict logic. I happened upon a very unfriendly comment complaining about the speed of the presentation. I will acknowledge that the pace is challenging, but I find that pausing and backing up provides for valuable repetition and gives me a chance to really think about what is being presented. No sarcasm. No complaint. What I found HILARIOUS, was your suggestion that he turn down the playback speed. Honestly, that had never occurred to me, so I gave it a try. I highly recommend it if you're looking for a laugh. You sound SO DRUNK at 50%. LOL.
So when testing 13:09 reservations ResultView shows: Empty "Enumeration yielded no result". Anyone else got this problem/solution? My code is pretty much the same
Yeah I had the exact same problem, here is the issue: In the Reservation folder you need to use the "username" parameter like this: "public Reservation(RoomID roomID, string username, DateTime startTime, DateTime endTime) { Username = username; RoomID = roomID; StartTime = startTime; EndTime = endTime; }"
At first glance this kind of Model is overwhelmingly complicated, but thus fulfill the subject very thoroughly. Definitely we should learn from you Sean! Thanks!
Hi, i'm really grateful for your courses. And a question is how can i be member to see this playlist which is member only ...???? (I'm subscribed you ...)
Granted I'm not exactly a beginner but I actually do like the speed. I tend to just watch videos like these without following along and then implement the concepts in my projects at a later time. I disagree with the people who say it's bad I think it's just an intermediate level tutorial that assumes a certain level of familiarity. For those with problems I would remind you that MVVC and design patterns in general tend to be more advanced programming concepts. There is no shame in wanting a slower format that goes into more details but for people who are just looking to pick up MVVC and little else I believe this is actually a pretty good tutorial which is why it's the first result when searching for such a thing.
I'm a beginner, I would like to do something when I close the window, at the beginning I used the OnClosedWindow fonction in the code behind but I don't think it's a very good way to do that. I want to do the function in my mainViewModel. Someone can help?
Sean, I like the tutorial. It's one that actually builds a complete example. You move fast. This prompted me to study my snippets and shortcuts again. I am uable to build the project on my system. Visual Studio 2017. I get this error and some other realated errors: TargetFramework value 'net5.0-windows' was not recognized... Can you suggest a fix for this?
Hi i dn't ve to tell u this but i want to : i ve watched a lot a wpf's MVVC teacher but you re just the king of learning without any doubt. Thank you for your time& efforts. I have a wpf project about booking a workspace/dockingstation/work material... for employees .. the point is that i ve to group by room coz in the room it could be more than an employer , wht u think which models i ve to include in my models folder ?
Just to be clear, any properties that should be editable should have setters as well, rigth? Like if you could edit a reservation, the start and end dates should have setters?
That you for your videos they have been a big help. But I did want to point out for anyone running into this...conflict needs to check if reservation starttime is between starttime and endtime...same goes for reservation endtime. If you only check < or > then conflict can return true and there not actually be a conflict.
When overriding OnStartup, it throws no errors if there is only base.OnStartup(e); . However, as soon as I try to add any more code to the override, there is an error. It says that "base" is an invalid token.
@SingletonSean, want to hear the funny side of it? Play this video back at 0.5X speed from about 3:00 minutes. It sounds dope man. I wanted to hear what you said because you were going fast, so I played it back at 0.5X. Quite funny. Sounds like you on something haha.
Thank you very much! I've been doing programming for over a year now, but I always had the feeling that I couldn't build anything myself. You showed me how simple things can interact with each other and opened up a new vision for me in development.
I've watched a few Tim Corey videos, and he is soooooo slow! These are picking up the pace, and I can still understand what you are saying (not English from India).
Glad this pace was good jp2code! Pace seems to be subjective - I get tons of people complaining about my pace too hahaha. I definitely have room for improvement still 😁
Hey Tom, thanks for the feedback. I'm sorry this wasn't helpful to you. I understand your perspective though. Honestly, I've been doing this channel for a few years and feel like I haven't quite found the right flow and style. I've finally spent the past few weeks looking for ways to improve. Hoping 2023 will be better, and I hope you have a great new year!
The validation logic has issues. Validation first rule is to check if existing reservation is on same guest as incoming reservation. You either do that by looping through the filtered collection (get reservationsbyUser) or add checking guest name first in the conflict method
You edited out the name of the project....:( Also did you dub this after editing out time? You owe me 14 ish minutes of my life back because this literally had 45 seconds of actual MVVM talk in it. If college courses were taught like this it would require 200 years to graduate. Good information...bad format. With all the extra crap the viewer forgets the 45 seconds of relevant information.
Thanks for the feedback Buddy! I'm not sure what you mean by editing out time and editing out the name of the project. Based on your other comments, I'm sorry this series isn't living up to your expectations.
@@SingletonSean In the video I was watching what you typed in for the project name and it looks like frames were removed. Your presentation skills are good but people read your title and expect to learn about MVVM and how to implement it using C# and xaml. Th vast majority of the content however is editing non-topic items.
