### Bug Description Building an application with the `dotnet` plugin on `core22` currently errors out with: ``` Bad snapcraft.yaml content: - plugin not registered: 'dotnet' (in field 'parts.dotnet-installer') ``` It was previously possible to run snapcraft on the same `snapcraft.yaml` file. ### To Reproduce We can use the [canonical/dotnet-snap](https://github.com/canonical/dotnet-snap) application as an example: ``` $ git clone git@github.com:canonical/dotnet-snap.git $ cd dotnet-snap $ snapcraft --use-lxd --debug --verbose ``` ### Environment - Ubuntu 24.04 LTS - Snapcraft 8.2.8 - Using LXD - `core22` snap (I haven't tested with other bases) ### snapcraft.yaml ```shell name: dotnet base: core22 version: 8.0.4 summary: .NET CLI tools, SDK and runtime description: | .NET is the free, open-source, cross-platform framework for building modern apps and powerful cloud services that work on Android, iOS, GNU/Linux, macOS and Windows. .
