Prism for WPF 9.0.537 doesn't support .NET 10?

[GrahamDo]

Hi,

I've been using the VS2026 Migration Experience to migrate a large (>100 projects) solution from .NET 4.8 to .NET 10.

Things have been going relatively smoothly, until the point where Copilot needs to fix build errors, one of which is due to Prism namespace resolution errors. It's fixed a bunch of them already, but one of the things it's struggling with is Prism Regions support, which is says it cannot do because Prism 9.0.537 does NOT support .NET 10, and it recommends downgrading to .NET 8.

This seems suspicious to me. Can anyone confirm that this is the case?

And if so, is there a timeline for releasing a version of Prism for WPF that does support .NET 10?

Cheers,
Graham

The current builds of Prism for WPF do support .NET 10. It just doesn't have a specific assembly built for it that is publicly available. Our current .NET 10 specific builds are only available to our Commercial Plus license holders at this time.

Thanks, Brian :-)

Have you any idea yet when those .NET 10-specific builds might be made available in the public feed?

Cheers,
Graham

Unfortunately, we do not have any timeline on when exactly we will publish any updated packages for the public feeds.
