Bug Blank Template dont wants to build properly to WinSDK(packaged) target following the Counter c# mvux guide, incl. 90% solution recommendation

[DevTKSS]

Current behavior

Followed along the "Counter" Tutorial (c# markup, mvux)

1. new solution created from exact terminal line mentioned in tutorial in vs 2022 integrated Terminal
2. added the logo.svg into Assets Folder
3. followed up to the Uno.Resizitizer Guide -> created /Images/ folder in Assets, moved the logo.svg to there
4. set its properties to UnoImage like guided and then there were told to go to the ItemGroup for setting the path with .png ending
5. since the appmanifest designer in vs 2022 itself did not support the wanted actions (image was not detected in the [...] Dialog) and also didnt accepted the Non-Optional Version Numering (Version.Major 1 Version.Minor 1 Version.Build 1) I tryed to set just for making the red markings disappear and also this messaging saying this from manifest

7. so I searched all settings in vs but no where I found something that would solve that, so I went to the Package.appxmanifest file in solution explorer as last idea.
8. Found about 4-5 green underlinings for Attention Markers which will be the result of the errors in the before mentioned ProjectDesigner UI which did only told me "Not this way" but without any Solution-Recommendation.
   
   

Ah and one additional thing, I did not test: vs 2022 is telling me something about the android target, some problems, but clicked to quick on X because I do not actually target android on this moment, so might be a missing package or whatever, just to be mentioned.

Expected behavior

Build solution to any target (Skia Desktop do not have that problem! Just WinSDK!) from fresh solution template would be really beginner friendly laughing

Affected platforms

Windows (WinAppSdk)

Template Host

(the Name differs in my screenshots because I created a new project for showing you the before/after fixing the properties, but you do know that the name is the most irrelevant thing on this)

Anything else we need to know?

After some reseach, how Microsoft wants it's stupid package to be happy to at least build (one Warning is still there) I made a few changes, which I would like to share with Uno Dev Team to review for possible implementation into future templates, so the other newbes will not have to get upset because there is no easy solution way available (at least what I found so far)

1. Marking: Althought the Graphical Editor from Visual Studio do not give a 4. Input Textbox it do not accept 2 or 3 places, it have to be 4 (at least on my vs 2022)
2. Marking: Publisher Attribute is not possible to be set via GUI of VS 2022 without having to create some stupid certificate (which can result in other trouble with registration)
3. Marking: optional! Can be ignored for this, just had it added there and my screenshot programm didnt support individual marking delete.
4. Marking: I added this manually here like mentioned above(that is most likly what you told in the tutorial if I am right), because the GUI did not found the .svg image before building which makes the resizitizer create the png you mentioned in the tutorial, but without this Logo set there (not relevant which one if its just a valid image) the compiler will prompt this to be missing property of the Identity tag.
5. Marking: Call it stupid, but this fu*** compiler absolutly want's this stupid BackgroundColor set there and since I did not get until the "how to set colors in my application that are defined in styles" (this will be in tutorial I am abolutly sure about that) I just typed in some hex code to make the compiler happy so it might show me the application I created as packaged windows sdk app.

And thats it! giving the version number as 4 places, publisher, the Logo and BackgroundColor it had build on my win11 machine.
I mentioned the "90% solution": Like you do see down below the markings, "<rescap:Capability" is still be pointed out as Warning, but do not disable the build process. Just after changing the file there you should restart vs 2022 with the project other than me. It did tell me, that a new build process can only be started after ending the last one and it catched itself in a deadlock with the errors I showed above.
Problem is, that inside of the Capabillities tag, Intellisense do not seem to know rescap althought the import was done on the file head. ms documentation did not gave me any solution and gpt tells me exactly what there stands to be the right thing.

I hope, this can help you improve the template in any way, so the application might be able to build. maybe you could implement some kind of uno ui for input the needed values? I dont know the possibilites in templating projects, thats your expertise :)

Kind regards!

Thanks for the detailed report! We'll take a look to improve our templates.
