Hello,
I'm following these instructions:
https://learn.microsoft.com/en-us/dotnet/maui/windows/setup?view=net-maui-9.0
I'd previously tried Geralds command line build but that failed and led me to the article above.
I imagine its still pretty new but if anyone has any suggestions I'd appreciate it.

- The Maui version.
- What Nuget Pakcage did you quote? Do they support the corresponding MAUI version?
Your prompt reply will be highly appreciated.

The pdb I quoted isn't a nuget package, its a maui UI library I made so I can share it between other projects.
The only way I know to get my Maui Version is by running the workload list, the output including an unnamed exception are here:
dotnet workload list

Use
dotnet workload searchto find additional workloads to install.Updates are available for the following workload(s): android ios maccatalyst maui-windows. Run
dotnet workload updateto get the latest.Unhandled exception.
I was not expecting the workload list to download files but I'm thinking it didn't actually install them just gets them ready to install. A bit shy about doing the workload update, last time that screwed me up for days.
