❓ System.TypeLoadException in Uno.Material.dll after upgrading to Uno 6 — is Material V2.X.X compatible?

[Soap-141]

Hi Uno team 👋,

I recently updated my project to Uno Platform 6.0, but I’m still using Uno.Material version 2.X.X. After the upgrade, I'm getting the following exception at runtime:

Exception thrown: 'System.TypeLoadException' in Uno.Material.dll

It seems like there might be a compatibility issue between Uno 6 and the current version of the Material package. However, I'm looking to keep the same material version since I don't want to have to change all the keys and fix regressions.

• Is Uno.Material 2.X.X compatible with Uno 6.0?
• Are there any breaking changes or migration steps I should be aware of?

Thanks in advance for your help!

On Android, I'm getting

Edit, I've managed to fix the issue with windows, by updating less packages, however, I'm still getting the same on Android, WinUI doesn't reference Uno 6, which might be why.

iOS I'm getting an error similar to 'uno missing method framework element get is enabled' I could not copy it in time or screenshot it, the debugger is crashing

Managed to have more trace on Droid. Android [0:] System.MethodAccessException: Method Microsoft.UI.Xaml.SolidColorBrushHelper.get_Transparent()' is inaccessible from method Uno.Material.__Resources._mergedpages_v2_44627d8de4433209f2b1934267892e44_mergedpages_v2RDSC1.Build(object)'

Very likely v2 is not compatible with Uno 6 - is that correct @kazo0? Can you try migrating to v3?

Yes, I've tried many versions, and it looks like it must be a version compatible with Uno 5+, from my understanding. At this point, I think it might be worth upgrading everything and fixing the visual regressions because I'll end up spending as much time trying workarounds when I have to update one day anyway. Thanks!
