📝 the page output was moved to an embedded resource, which is generated by modifying the #define at the top of the test file and otherwise loaded from disk for the test

📝 This line is the only change to this file relative to the original string. The change presumably occurred because AdditionalFiles now includes an absolute path to the razor source file. It's not clear to me whether a full build with the source generator running will use an absolute path here or a relative path here. If it's a relative path, I'm not sure where it's derived from.

📝 This line ensures that we don't hit NuGet for anything during testing (unless a specific test overrides this property to a different value).

📝 This manually adds MetadataReference items for all the items that were being added to the old tests. The whole block was copied from CreateBaseProject().
This is a proof of concept for discussion.
