Stumbled across this video by accident. Top notch and instant subscribe! This is one of the best WPF tutorials I've seen on the web. I'm assuming now that the first 8 are the other ones!

I've watched a bunch of your videos, they are great, thank you!. Here's what I can't figure out though, how would you switch between pages using a RelayCommand (say button is clicked)??

Great job man! Really!
I haven't found any better video tutorial than these in any other language (and I've seen many).
Keep doing this! ;)

Side note: don't know if you considered this yet, but it would be great if in future tutorials you'd show how to "re-use" Models and ViewModels on other platforms (thanks to the MVVM pattern) and use it to create mobile app or web app, as you indicated in one of your first videos.

For those guys, expect the font awesome icon in design time but only squares. Don't know the exactly reason, I simply change the font path to [ <FontFamily in Fonts.xaml. Problem solved.

I am using the "Latest code" and when executing, the program stops with error in the file: App.xaml.cs line where: await ApplicationSetupAsync(); is located
ERROR:
System.AggregateException: 'An error occurred while writing to logger(s).'

Inner Exception
IOException: The process cannot access the file because it is being used by another process.

It compiles without error. The error appears in runtime. Any idea or recommendation? I am using VS19.

Hello Angel,

There is an issue in the WindowResizer, because if I'm using it I'm able to resize the window smaller than the Min Height/Width. I tried to find the solution inside your resizer class, but I can't really understand at all where I can pass the minimum values.

Can you help with the solution ?

[christopherbaldwin]

Thank you great explanations and clear to the point.

Hi Luke,
I sent you one email about user control dependency property. But mail turned. How can we use dependency property in a user control? when I put user control to the main window. with size I want to see dependency property value at the same time?

[jojoduke]

What is the benefit of using a user control instead of just making it in the window?

Hello sir, how to set drag and drop user controls ( i want to set waiting order names of the customer and which can be adjust by drag and drop function)

There is an issue in the WindowResizer (not sure when that slipped in. Itwas working at the beginning of the course).
When you dock left or right the window does not get resized, so the outer margin and drop shadow remain.

In the Window_SizeChanged event handler the first 2 lines that check if mTransformToDevice == default(Matrix) never return false, so the rest of the code never runs (at least I didn't manage to). Removing that check seems to get the wanted result. But I am sure that there is a reason why you put it there.

The reason for that, in my opinion, is in the GetTransform method.
The following line always returns the same values as default(Matrix), so the later comparison in the event handler always is true.
mTransformToDevice =

As my skills are too limited, I can't find the solution for this myself. Any takers?

For docking in general I have to say that we are missing the quarter positions that were introduced with Windows 10 (I think).
So I think we need to add docking positions for UpperLeft, UpperRight, LowerRight and LowerLeft, just in case. I haven't tried, but I believe I can figure that out.
