3 years ago Thanks, I've got a repro of this as well and an idea to fix it. Unfortunately there's a few places the template can end up and I'm not checking one of them.

3 years ago @Redth The latest commits you've done related to the manifest fixes the issue. I'm facing another one, the system don't find Microsoft.Maun package, but I haven't investigate it yet. I'll take a look.
Cheers

3 years ago Fixed in newer versions/previews.
I'm trying to follow the guide found here to play around with Maui.
The first time I run the maui-check tool, it installed a few things, but I couldn't get my example to run. So I tried running the tool again, and it said "Microsoft.Maui.Templates" was missing and it tried to re-install it, but it doesn't seem to be able to. It doesn't log what goes wrong, it just doesn't find it on the next run. I don't find it in my packs folder either.
The output from a run (maui-check -dnf) is:
` _

! There were one or more problems detected. Please review the errors and correct them and run maui-check again. `
I've tried the --verbose flag without getting any more information about why it fails. Installation of the pack obviously fails somehow - how can I find out what went wrong?
