Hi Brian. Thanks for this video. Can we have this cancellation token implemented for Background Service as well - can we cancel the task via UI screen ?

Finally, i understand yield return better

44:34, It's cleaner to check that they don't exist in the cache then to check if they do. If they don't exist in the cache, then create and insert them into the cache. After that bit of code, you just have code that assumes that the cache exists because it does. This is a single threaded method here, we don't need to worry about race conditions. This turns that if...else into just an if-statement. Also, that var was of type 'List<T>'. An 'IList<T>' doesn't have to be a 'List<T>' which is why you can't assign an 'IList<T>' to a 'List<T>'. It's find to do it the other way around because a 'List<T>' is an 'IList<T>'.

That thing with the bad namespace assigned to "igWPF" stopped all my intellisense from working. Don't you just LOVE how Microsoft keeps improving Visual Studio.

Good video. I don't get one moment. How did background thread from thread pool changed text on UI? Method DoSomething is executed fully on background thread?

As of June. 2024: Infragistics Nugets now have ".Trial" added at the end. It will just add a watermark over the running program. You can still use them without making an account or entering a trial thingy. Just use it like he did in the video

Timestamp 42:00ish - If you (like me using VS 2022) can't see the "Reference"-Icon he has under PrismOutlook. You can add the Reference by RightClicking the project PrismOutlook -> Add.. -> ProjectReference... The same window he has will pop up. Then "Rebuild" instead of "Build"

Question, do you know if it's possible to use Infragistics.Documents.Excel to find the last filled row in an Excel File? I've been trying to use that for data, and have had a slight bit of trouble.

So TL;DR, UI = true, Library = false. What happens when Library code is used in a UI?

Hi Bryan, This was a really helpful video in trying tog et my head around MVVM, but scrolling through the comments it looking for ways to add data to the dialog box. I.E. I want an exception window that provides a call stack and exception message and a Title as Parameters I send in to be displayed and I have more generic Dialog box that does not need anything but a message. The only solution I saw was make an overload to the show dialog with more parameters and restrict your Views to those with View models that have this interface. This feels... Overly complex and brittle. Each time a new Dialog bog with a new Input configuration is created we need to ake a new interface for that ViewModel and then make sure the view specifed for the show dialog has a view model of that interface type. is that correct? At that point it starts to feel clunky... Do you have any better solutions?

Great video. I hope you start making videos again!

I See states machines where? Everywhere

thank you a lot for the tutorial yet it throws me and error: The non-generic type 'IAsyncEnumerable' cannot be used with type arguments IAsyncEnumerable<string>

such a complicated concept taught so easily, wow, appreciate it

How can I clone this teacher and spread him to all IT institutions?

Another brilliant video, hope you will come back to teach us more! Thank you

Very very good explanation, thanks a lot

Good one thanks :)

Nice!

Excelent video! The best explanation!

Thank you for this video.. You explained everything so clearly.

Can one add dropdown menu in cell? Thanks for the wonderful video.

why you are soo good at teaching ? dayuuum i swear i'm not just complimenting you , your teaching method is clear and straight to the point which is something we often miss IRL in schools, and also online .

I lean towards the 1s option, but my question is: how do I execute code that's posted on GitHub by someone else? They've organized it into different packages, and these packages are called in the subsequent code. However, when I attempt to run the code, the packages aren't recognized

Awesome explaination. I failed to understand other explainations of this type but yours was clear and easy to understand.

Great explaination. I try to avoid async void when ever possible. The only place I've seen it used have been in developement with Winforms but nonetheless a good solution to the problem.

Hello Brian, thanks for your valuable content. I suggest including the DependentView attribute and the region behavior internally in the prism library as a feature included within the library (battery included).

24:30 where homepage starts

That is incredibly helpful. The idea of using Yield Return when you are unsure how much data you may be going over is especially helpful.

Okay how can i find the password?

Hi Brian! We are using Prism MAUI, what if you need to refresh a page with tab views and its structured in a way that each tab has a command to be executed that refreshes its own content that the parent page can invoke, and each command may require a different parameter provided, can the Composite Command handle this type of situation? I don't currently see a way to do so but then maybe I am not using it as intended.

26min to show how to display a simple dialog. Winforms was ahead of his time.

I am interested in how .NET knows how to treat IEnumerable and IQueryable. Maybe to the point - when I am accessing some entities, for instance from the EntityFramework like so: `IEnumerable<Person> people = dbContext.People;` then it's clear how it will behave but things are getting interesting when I will cast to the `IQueryable<Person>` -> `var peopleQueryable = (IQueryable<Person>)people;`. It still knows the difference and makes queries different. So for instance we add some Where instruction then it will fetch the data and then it will calculate it in the memory but for IQueryable it will add the WHERE statement to the SQL query instead of fetching all the data.

Thanks Brian - very helpful. I tried for days with DevExpress DialogSrvice and just coludn't find a way to resize them - that was the only problem! Learning to "hand roll" them has great beneift.

So clear Brian

When the if condition becomes false, then the task is skipped, but the task should not be skipped until the condition becomes true.

get on with it!

Jonny333 you'll see it

Brian ! Please help me! This guy hacked me then put up a video of it! Complaining that he couldn't get into my phone! Wtf!? This A*sMonkey! Stopped me from having my hearing at unemployment and now they want me to pay them $23k?

great tutorial!!!!

4:12 😂

is there any reason using Activator CreateInstance not a new T()

bravo!

I like your method to open any dialogue from the viewmodel i used it on xamrin forms but the pages freeze until the viewmodel load and get all data from database my question is how to load the page fast then let the viewmodel do his staff then update the UI so my view or page not get freeze, thanks in advance

У меня не возникает DeadLock как в конце видео, хотя я сделал всё идентично. Я не понимаю почему он должен возникнуть. Почему .ConfigureAwait(true) вдруг должен ждать какого-то ответа от UI потока? Если мы говорим этим выражением, что хотим продолжать код в UI потоке. По логике второй поток должен выполнить дополнительный процесс, закрыться и передать управление обратно UI потоку. С чего бы второму потоку при await ждать первый?

Very clear explanation, thank you!

What a great channel 🤩

What if I don’t/can’t use polling? Like a db task which may take too long n I just want to timeout?

is this project considered as intermediate - hard ? i started c# wpf about a month ago and I'm wondering if this project is a good way to start & learn Prism as well as WPF
