.NET MAUI app completely broken after Visual Studio 17.14.17 update - .NET 8 project no longer builds or deploys (was working fine before)

This might not be the most obvious fix, but what finally worked for me was upgrading the entire stack:

• Migrated the app to .NET 10 workloads for both Android and iOS.

• Updated Xcode to version 26.

• Installed Visual Studio 2026 Insiders Edition.

Once everything was aligned with the newer toolchain, the app started building and deploying again without issue.

Granted, I was able to do this because I’m the sole developer on the project, so I didn’t have to worry about team-wide compatibility or rollout delays. But I wanted to share this in case anyone else is stuck and has the flexibility to try the same path. It’s not ideal, but it got me unblocked.

Hope this helps someone in a similar spot!
