The SDK-style writer only ever emitted EmbeddedResource items, so every other
item type the export produced never reached the project file. XAML recovered
from BAML lands in Page items: ILSpy wrote the .xaml files to disk and the
project referenced none of them, leaving an exported WPF project that cannot
rebuild.
Explicit items collide with the SDK's own globs - a UseWPF project globs
**/*.xaml into Page, and NETSDK1022 rejects the duplicate - so each include is
preceded by a remove of the same item type, the pattern the EmbeddedResource
path already uses. Setting EnableDefaultPageItems=false would work as well, but
it is WPF-specific and switches off a glob for the whole project, whereas the
remove is per item, applies to any item type, and keeps the SDK's item
definitions (XamlRuntime) in effect.
