Worked it out. Constraints.

Thanks. I managed to add the required resources with this UTType value. Sorted. 😀

What do you mean "notarized"?

I see something about it but need instructions for VS for Mac.

I think I have it working. There were a lot of unknown steps. I stumbled on a useful page: https://developer.apple.com/documentation/xcode/notarizing_macos_software_before_distribution/customizing_the_notarization_workflow?preferredLanguage=occ#3087734

I expanded the PKG into a temp folder and I saw: install-location="/Applications" auth="root" So it seems it should have installed to that folder and not the folder where the PKG was.

My colleague uninstalled the application and tried using the PKG file a second time and it did install to the Applications folder. I am not sure why it failed the first time.

I would like to know too, for iOS and macOS. How we can do xslt transformations. Doesn't the support staff read these questions?

I now see two related questions - 8 month and 5 months. No response from Apple. ??

Here is the really odd thing ... If I set the focus to the WebView and use Print from the File menu, it is fine! But if I use: var appleViewToPrint = Platform.CreateRenderer(viewToPrint).NativeView; var printOp = NSPrintOperation.FromView(appleViewToPrint, NSPrintInfo.SharedPrintInfo); printOp.JobTitle = "Elderly and Infirm Rota"; printOp.ShowsPrintPanel = true; printOp.RunOperation(); It is blank.

Turns out that there was a problem with my code that installed the default data. Oops.

This was my fault! I had added the CSS file and the Build Action was set to Embedded Resource instead of Bundled Resource. Now it is fine. 😊

It seems to be OK now. Admittedly I changed the version number, tried Release build, and upgraded to latest Big Sur. But after all those changes the Help Book now matches all the changes I made.
