This is the best place to learn MVVM. Thank you for taking you time to share this with the community.

One of the best videos to learn MVVM, with great explanations with clear, non-redundant language. Thank you so much for making this.

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!

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.

Straight to the code with a good and clean example project. Maybe it’s a bit too fast for absolute beginners but I loved it

I agree. For someone that wants to follow the steps, I need to stop the video all the time so I can follow along.

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.

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.

Great video! Keep up the good work!

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 then conflict can return true and there not actually be a conflict.

Well put together video.

10:46 Why in my case it didn't add the parameters to the existing constructor, and instead the menu option creates a new one?

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.

Soo gooood! that's all I can say :)

HI, great ressource, what version of c# and .NET freamework you are using in this project?

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?

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.

hi, can you help me a bit with my project? I must split Logig and UI but i dont know how to da it... It would be mega great!

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?

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?

There is a problem of hashcode i try to install the package but not work.

This is a good tutorial but some of the Visual Studio code generation magic is skiped over too fast to understand what he's actually doing.

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. :)

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

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

most MVVM tutorials shove all the domain logic in the VM. Its rare to see some proper model design.

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?

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.

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!

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 😂

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.
