Visual studio 2022 Maui project unable to compile for .net 9.0-ios target

Ryan Lee 25

Hi,

I am trying to deploy a test app to iPhone from windows visual studio but getting the following error when trying to compile.

The specified network password is not correct.

I have completed the automatic provisioning :

User's image

I obviously have no problem compiling for android emulator.

I have tried removing the folder AppData\Local\Xamarin, removing bin and ojb folders, relaunching the app, and going through adding apple account again, confirmed there is at least one valid certificate in the list of chains.

Can someone please advise if there is anything else I can try to do?

Thanks

Ryan.

The device is plugged into your Windows machine, and you are using HotRestart, right?

confirmed there is at least one valid certificate in the list of chains. I want to double-check the confirmation steps: Open MAUI project, go to Properties window, select iOS->Bundle Signing->Scheme (Manual Provisioning)->Signing Identity (Developer (Automatic))->Provisioning profile (the profile you have generated).

If not, how did check the certificate and provisioning profile?

The specified network password is not correct.

On which step did you have the problem? Could you share the context with me? As described on the Doc, you meet the issue at Deploy and debug using hot restart section, right? On step3? Also, you could check if you can update the VS to the latest version.

I just updated my app to .NET 9 from .NET 8 and this has started to happen for me today as well.

Prior to the upgrade to .NET 9 it deployed ok using Hot Restart, then I started seeing this error message about my password.

Hi @Andrew Taylor-Brook , could you select the provisioning profile manually?

When I set to manual - unfortunately it still fails with the same error :

C:\Program Files\dotnet\packs\Microsoft.iOS.Windows.Sdk.net9.0_18.2\18.2.9173\tools\msbuild\iOS\Xamarin.iOS.HotRestart.targets(40,3): error : The specified network password is not correct.

Yesterday after posting, I thought i'd solved it as it seemed to stop happening temporarily - but now it's back again

Got the same error when I updated from .NET 8 to .NET 9.

This happens when I try to debug my MAUI app from my iPhone that is connected to my PC (Windows 11).

The specified network password is not correct. MyProject..App (net9.0-ios) C:\Program Files\dotnet\packs\Microsoft.iOS.Windows.Sdk.net9.0_18.2\18.2.9173\tools\msbuild\iOS\Xamarin.iOS.HotRestart.targets

OK, i can now reproduce the issue and also work around it

Steps for me to reproduce the issue :

Open VS

Connect iPhone (so it shows an available local device)

Build project

Debug to iPhone (Succeeds)

Stop debugging

Modify .csproj file in any way (e.g. just add some whitespace in) and save

Debug to iPhone (don't explicitly build)

Error about password appears.

Build the project

Debug to iPhone (Succeeds)

So the main issue seems to be if the csproj file changes in some way but you don't build the project, the error appears until you do another build.

I converted the comment to answer, thanks for your sharing. About changing the csproj issue, it's an IDE problem, please report the problem with VS, see Report a problem with Visual Studio - Visual Studio (Windows) | Microsoft Learn

This does not work for me so this should probably not be marked as the answer. This is an obvious bug since there are a lot of people getting this at the moment. Not only in this thread...
