iOS Extension project deploys on iOS simulator instead of MAUI Hybrid Blazor project

[vitalbit]

Type: Bug

Describe the issue
I can not find the way to run MAUI project when solution contains IOS Extension project (verified with Notification Content Extension and Notification Service Extension). When you try to start debug, the IOS Extension project is deployed on the simulator (meanwhile you can notice that "dotnet build" command runs with correct MAUI hybrid blazor project in arguments).

Steps to reproduce

1. Create new MAUI Hybrid Blazor project in VS Code on MacBook with .NET MAUI extension.
2. Add Notification content extension project (can be achieved with the help of this nuget package https://www.nuget.org/packages/VladislavAntonyuk.DotNetTemplates)
3. Add Project reference in the MAUI csproj file to the extension project, as stated in README.md of extension project.
4. Pick iOS Simulator and run MAUI build.

Project sample, which have such issue and covers first 3 steps: https://github.com/vitalbit/IOSNotificationExtensionSample

Expected behavior
MAUI hybrid blazor project is deployed on iOS simulator, not iOS Extension project.

VS bug #1890216

[RcBrgr]

Same problem with plain dotnet Maui project with iOS App extension.

[stepkillah]

Any updates or known workarounds? still an issue, a partial workaround is to exclude extensions from the main project

[mauroa]

Just as an update after some investigation, iOS Extensions for VS Code is not fully supported, so we need to convert this into a feature request. We'll work on it and provide updates when the support is ready. Thanks for your help and patience.

[evgenyvalavin]

Same for me

[SharpMobileCode]

Same issue here. We have a single project .NET MAUI app targeting iOS & Android, with an App Extension project for notifications. Every time we start new debug session, it deploys and installs the Notification Extension project instead of the actual iOS project. We're evaluating the VSCode extension now that it is GA and is a show stopper for us. Don't think this is a feature request, it's a bug as the VSCode extension is the official replacement for VS for Mac, and this worked fine on VS for Mac.

This is now fixed in the latest prerelease version of the .NET MAUI extension for VS Code (v1.8.5).

Just to clarify, .NET iOS extension projects are still not supported from the tooling, but now referencing those from a .NET iOS/MAUI app project, won't interfere with deploying/debugging the app.
