Question

How to deploy Maui App to client to install without turning on developer mode?

Lohith K K 110

I have developed a .NET MAUI windows application. Now I want to supply the same to the client to use it in their company for multiple users. I have created appx package and delivered the same but with this package to install the software user need to turn on developer mode in their machine. But, due to security reason client management do not want to turn on the developer mode.

How can I resolve this issue? How to install app without turning on the developer mode?
Some more info which may help: Client is using company portal to list all their applications. With the help of Microsoft Intune, they are adding the application into company portal.

Also, I need to install the application from company portal without user intervention. As of now PowerShell window pops up and user needs to accept the question to install the application. It will ask permission for certificate installation.

Firstly, you can publish your application to a folder.

, not able to install the MSIX file without installing the certificate.

You can find this certificate(Normally this certificate called yourporjectname.cer) in this folder and set it to your trusted root.

For installing it first you need to register its certificate.

Simply right click the MSIX and click Properties

Go to Digital signatures Tab

Select your account name and click Details

In next popup select View Certificate

In next popup select Install Certificate

In next step select Local machine (If a user account prompt appear click yes)

Select Place all certificates in Following store and click browse select Trusted Root Certification Authorities or Trusted people and click OK and Next

Click Finish

Confirmation windows will appear After that Try Installing the MSIX

Thank You Leon Lu for the detailed information about the certificate installation.

But my original question is different. Below is my original question:

Answer 1

If you're getting a PowerShell message about turning on developer mode, it's because you're running a script to do so. This is likely the Add-AppDevPackage.ps1 script that Visual Studio generates when creating an appx. That script shouldn't be used for production. It is designed for development / test deployments, and two of the three things it adds to the install are turning on developer mode and trusting your test certificate. Neither of these are needed or appropriate for production.

For production deployment with Intune, you (or more likely, your IT team) will need to sign the app with a trusted certificate and then deploy the MSIX and its dependencies. See Distribute your MSIX in an enterprise environment - Microsoft Intune.

If you need more help on configuring Intune, you'll probably need to post a question specifically about that under the appropriate Intune tag.

Thank you, Rob Caplan,
This seems to solve my issue. I will create another question with right tags to get more clarity.

Hello @Lohith K K !

Please note that the correct output for your MAUI Windows App is a MSIX file.

The Package.appxmanifest is just a configuration file, not a deployment one.

Normally the MSIX file should be under your bin/release folder after a successful build or publish.

Here, you will find two different ways to publish a MAUI windows app:

To install a MSIX package using PowerShell, refer to this page, or create a new question on the appropriate tag:

Thank you Leo Wagner de Souza for the reply.

Yes, you are correct about the MSIX package.

But my question/concern is different. Now I have a MSIX package, and I want to install the same to client machine. But when trying install, it is asking to turn on developer mode in that machine. How can I install the application without turning on the developer mode?

Please see my question how client is distributing the application to users.

Please check if you are generating the MSIX package in "Release" mode:

After that, try to install the MSIX directly on another computer, without use Intunes, and see if it works.

Yes, I am generating the file in release X64.
Followed the same procedure, not able to install the MSIX file without installing the certificate.
