[@bity-bite]

Great video as usual. I'm kind of disappointed of Xamarin.Forms and MAUI due to the fact of how hard it is to style native UI controls. I absolutely love how Flutter does it, beautiful UI as easy as it gets.

[@jfversluis]

Thank you! Sorry to hear that. I think it's important to realize that Flutter and .NET MAUI differ on this point fundamentally. With .NET MAUI we're definitely investigating to also achieve this easier, but that will come in a later stage. You might want to check out Microsoft.Maui.Graphics.Controls for a nice initiative that tries to do this.

[@dotnotstandard]

Hi Gerald. Thanks for the video, very interesting. I'm not used to MSIX/signed app distribution, so this is more of a question about that really. I'm wondering about what happens when the signing certificate expires. Presumably the app cannot be installed on a new machine after the certificate with which it was signed has expired? Will it even run after that point - is the signing only checked at the time of installation, or each time it executes? Do the answers to these vary between self-cert and an official dev signing cert from a trusted authority? My guess is that, if self-certifying/side-loading, then the certificate needs to be regenerated and reinstalled each time it expires. Is it true to say that this will not be an issue with an official dev certificate from a root authority, as they do not need to be installed (because the cert signing chain goes up to a root cert that is installed, and presumably managed via Windows Update or similar.) I'm imagining how cert expiry might make creating a small app more difficult, as you might have to repackage/republish it regularly, so that a package is always available for download that is signed with a current certificate? In other words, if I published an app and then didn't ever republish it - because it needed no updates - then it would pass the point at which installation can be carried out because the cert has expired? Thanks in advance.

[@GiovanniGambino]

Hi Gerald, I did my first porting from WPF to MAUI. AMAZING and EASY! Now I'm trying to understand how "automatic update for a sideload app" works. I mean: is it enough to copy the published content to an IIS folder? Have I to rename some package? Have I to add some file? Have I to add extra code to my app? I have some confusion for this task. Can you make a video to explain pratically the procedure or if you have a link that describes a step by step procedure, can you share? thank you so much! :)

I think there are currently issues with msix on Windows Server, not just for .NET MAUI, but in general. I think it was never intended to run on there, but it’s being looked into. I think. Try looking for an issue in the .NET MAUI repo for all the info

[@jfversluis]

Check your Properties/launchSettings.json. Looks like it says None in there for the commandName, but that should be MsixPackage

[@snooki9]

Hi Gerald Thanks for that. Something that I wonder, is the fact to publish your app on a store (Windows, Google , Apple…) protect it from being « cracked » (By than i mean copy to an other computer without upload it on the store). Or is it something that should be think about in the app code ?

[@jfversluis]

Publishing to the store should help with that, but nothing is perfect. There was this library to detect certain things in your code if that's what you want: github.com/nmilcoff/BreachDetector

Hey Gerald, Thanks for the guide. I followed everything exactly and it works on my development pc. My question is for the sideloading route. I put the msix on an USB to try it on different PCs and when I install it from there (from the USB) on my development pc it works. The app launches. But when I install it on a different PC (after setting up the certificate, all from the USB) the install works, I see the app installed. Then, when I try to start the app it shows the little loading spinner for 1-3 seconds and... nothing. Tried this on 2 different PCs, one running Windows 10 and another running Windows 11 stable. My dev PC is on the Windows 11 preview channel. They have the .NET 6.0.2 SDK installed, but not Visual Studio. Only my dev PC has Visual Studio installed. Do you have any ideas how to fix this?

Strange, I tried that and it seems to work for me. Is this a regular .NET MAUI app or a Blazor one? You could check the event log to see if that gives you some information. My guess is it will give you some missing dll message
