WiseJ 4.0.1 Hybrid app template with net-9 assembly reference issues #4809

Nick Welsheimer asked 2025-07-08 18:05:17 UTC

I'm trying to create a test hybrid app using Visual Studio 2022 (17.14.7), the latest WiseJ 4.0.1 VS templates, using net 9.0 for the framework version (this is the only option I have when creating the project from the template). I was attempting to follow along with the example in your documentation (https://www.learnwisej.net/wisej.net-for-business-applications/building-a-simple-app-with-wisej.net-hybrid) for a starting point.

On my machine I do not have net8.0 as an option. Using all of the default settings from the new project wizard for a Wisej.NET 4 Hybrid Client Application (which defaults to net9.0 on my machine), I have two errors right from the start.

Type or namespace Wisej not found, and MauiAppBuilder doesn't contain a definition for UseWisejHybrid. Both of the errors are specific to the net9.0-windows framework, it appears the net9.0-android & ios frameworks would build fine.

I haven't been able to find any documentation or discussion on the forums about the min/max framework versions compatible with wisej hybrid, aside from needing VS 17.4+ for net8 compatibility, but it doesn't specifically say it's required.

Any suggestions on what I could try to get this running? Are there docs or examples available for hybrid apps on the 4.0 update?

Appreciate all your help!
