Yes! Great video! I was waiting for this one! Thanks a lot Gerald 😁

Oh man, thanks a lot for this video. Extremely useful.

Hi Gerald, Could you make a video on publishing with automatic updates on? because I cannot get the installer path to work. Thanks

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.

Thank you Gerald, this is a very useful useful stuff.

Great video, Missed MAUI next preview uodate video from you , hoping to see it soon.

Great video! Thanks!

Thank you so much for the detailed video. I followed all the steps for self signing and it works great in my local machine. Where as if I copy the app package in different machine then it install successfully but do not launch my application. And I Checked the error in EventViewer it says "C:\Windows\System32\KERNELBASE.dll". Any help is greatly appreciated

Hello, how can we change expire date on self signed certificates?

Hi jerald, i have one question target platform only windows. When try to upload sideload package Generateappxpackage issue occur. When using command line publishing it works fine. But why it not working. Another question as well when try to command prompt is there any option to nuget package for particular path. Thanks advance

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.

Great Content - Love this Channel! Maybe I posted my video idea incorrectly (looks like it got deleted) -sorry. Great show! Keep up the good work!

Hi Gerald. Has this process now changed with the latest versions of VS2022 Preview, and do you follow the same process for a Blazor Hybrid application when you wish to deploy to the Windows Store, or Sideload?

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 ?

That is what I call good educational content, I have a question, when starting a new project on widows in .net maui preview 13 there is this grey thick title bar and it's very annoying do you have any idea how to remove it? also do you know how can I package the app without the msix package with a normal installation wizard like most programs? Thanks in advance.

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! :)

Love your videos both professionally and personally! Quick question - if I need my MSIX to work on older versions like windows server 2016, would it work to use MSIX Packaging Tool to edit my generated msix package to include MSIX Core support to the package? Thanks :)

Hi Gerald, how make a package that supports auto update feature on appstart? There seams to be an option in the VS publish wizard but I can't seem to use it right. Maybe there are bugs in VS? So I have to use the console commands. Thank you for your videos!

Hi Gerald. Thank you for this video. I get the following error when using the Developer Powershell in Visual Studio 17.5.4 "Improper project configuration: WindowsPackageType is set to None, but GenerateAppxPackageOnBuild is set to true" I get the same error for each of the 4 projects that my .Net Maui references. Hope you can assist. Thanks

Hi Gerald excelent video, I have a question, . Net MAUI is ready to develop apps in production? Thanks in advance

Nice tutorial I have been following ur videos on .NET MAUI and kind of contemplating to try it for my app development but somehow cannot commit. Do you recommend it as it is still in preview?

How do I install it in Windows 7, I have even tried to install the msix package tools so that there will be msix files but when I install it I get an error with the certificate, I follow the steps that I do with Windows 10 to install the certificate and in Windows 10 I It lets the application run perfectly but in Windows 7 it seems that it does not recognize the certificate that has already been installed

Hi, Thanks a lot, but I've got some error when I install distributing msix app on other computers. "app installer failed to install package dependencies. ask the developer for microsoft.windowsappruntime.1.0 package." How can I solve this?

Tried to install the .Net MAUI app project from a release and got an error: "App Installer failed to install package dependencies. Ask the developer for package. " why?

Thanks for all the nice Videos about publishing to Play- , App- and Windows Store. If you have some experience with the ML.net, can you make a video about this in combination with MAUI? Greetings

How to install MAUI app on windows 7? ( I got this error when I wanted to install it. "0x80070490 - Unable to open package." Is there any way to run that?

Hello. Very inspiring video. Thank you. I am wondering why you do not have "enable sideload apps mode" error. I do when I copy the package file and run. I want to know if this is something that we cannot avoid, if we do not want to go to the store. Your insight would be much appreciated. Thanks in advance. Kazu

Will there be no easy way to publish/share the app for Windows like for example with a WPF app? Can you create a single executable file for sharing?

@Gerald I published .NET MAUI Windows MSIX to sideload that is signed with a valid certificate. When I click .msix file, nothing happened because msix extension was not known on windows 10 by default. It seems that I have to install App Installer from Microsoft Store to recognise msix extension. After installing App Installer, I clicked on .msix file it showed me installer window, when I clicked on Install button it showed me following error: App installation failed with error message: Access is denied. (0x80070005). Why am I getting this error? Then I open power shell without elevated admin rights and run Install.ps1 script it showed me Add-AppxPackage : Deployment failed with HRESULT: 0x80070005, Access is denied. error. After that I run power shell with elevated admin rights, and run Install.ps1, then it installed my package. So it is installing sideload package only from powershell with admin rights. How can we make it installable by double clicking misx file without admin rights?

I'm having issues using a certificate issued from a trusted source. I converted a .key and a .crt to .pfx using openssl then selected that file from 'Package.appxmanifest' but got an error "The manifest Designer could not import the certificate." I have that cert installed in Personal, Trusted Root Certification Authorities, and Trusted People.

Hi Gerald, I'm trying create and sideload publish my .NET Maui windows app msix to my own windows server(through hyper-v) for testing if "auto-update" works. I spent days trying to follow the Microsoft docs but I can't seem to figure it out. Reading the rest of the comments, this seems to be the same as @GiovanniGambino's concern. Can you please make a video to teach us how to do this, please??

Hi Gerald! Did you leave the link with the codes? Sorry if it's here and I didn't find it...

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? Thanks in advance. - Ruben

Thanks GV. Its complicated. Could a customer or client of mine could install from link or downlaod from a some sort of portal.

Hi Gerald, in your opinion, what is the best certificate authority to Sideload apps? Regards from Brazil.

Thanks for the awesome video. For me the AppPackages was in the following location (not x64): C:\Users\Ruben\SolutionName\ProjectName\bin\Release et6.0-windows10.0.19041\win10-x64\AppPackages\ProjectName_0.1.0.0_Test Edit: Oops. I forgot to specify /p:Platform=x64 . Now it's there.

Is the MSIX file the same binary used for Windows mobile and desktop?

The whole steps for sideloading will not work for MAUI BLAZOR Windows apps, am I correct??

Can I also create an EXE or MSI installer in .NET MAUI?

Is there possible to create executable without signing ?

11:24 one small correction, GenerateAppxPackageOnBuild needs to be defined on the PropertyGroup node and not on the ItemGroup node.

Where i can find publish command you used

Great Content but how about hosting/publish dotNet maui Blazor Web application in iis. Thanks

Hey Gerald , can you suggest me another option to excecute msbuild command on non dev machine, so that without Visual studio I can execute the MSbuild command for my project and so that app would become deployable on (MAUI blazor windows app) on non dev machine when MSIX installs the app.

Please Create a video on Blazor MAUI Application CRUD Operations on DB with ef or without EF

Please do a tutorial for UWP signing and distribution to Microsoft store

I am getting below error while executing msbuild command: error NU1201: Project xxxxx is not compatible with net6.0-android31.0 (.NETCoreApp,Version=v6.0). Project xxxxx supports: net6.0-windows10.0.19041 (.NETCoreApp,Version=v6.0) Any help would be appreciated.

Password and ProtectTo cannot both be absent...m getting this error

How can i create an account? It's impossible.

Hi Gerald, your video is extremely usefull. Thanks Sorry to bother but I hope you can help. I've just experiences a small problem at the point where I'm to submit my app to the Microsoft Store... It 's the current required use of [] in the Package.appxmanifest. The app does not compile without that setting, but when submitting it to the store, the app appears to get blocked. Here is the comment... [We detected the use of one or more restricted capabilities in your Package.appxmanifest file. You must request approval to use restricted capabilities by providing more information below. Please include as much detail as possible] So, I've tried to explain, blaming it on the pre-release state of .Net Maui, but it appears not to help . Its been two days now and I'm still waiting for some feedback of sorts. Would you maybe know how to get past this problem? Thanks and regards

When I use the Publish funcationality from UI was able to publish and load onto another machine by putting the cert in the proper store. So, I was able to do this sideloading publishing process done through the UI using the Publish menu but so far no luck using msbuild due to F# library project issue which I assume is a setting somewhere. Good news is when I use the UI right-click Publish functionality I don't see this error and the Install files are created in the directory and able to be installed on another machine.

I was not succesful in running the MSBuild, It shows a strange error that parameters are not valid: Microsoft.Build.Msix.Packaging.targets(341,5): error MSB60 11: Invalid parameters passed to the Microsoft.Build.Msix.Symbols.WinAppSdkCheckFastlinkPdb task. EDIT: Actually this error us meaningless, deep in the x64 folder I did find the MSIX file which I could use to submit app to store and successfully download the app and run it.
