@ryanbrandenburg any ideas?

[riboyama]

There isn't razor support for arm64 yet. Building https://github.com/dotnet/razor-tooling/releases/tag/v17.0-preview3 yourself with osx-arm64 in the csproj works fine. You can specify the path to the languageserver in settings.json

[jtsom]

Not sure how "arm64" vs not arm64 matters. Taking out the two On... parameters from the EditForm, but keeping the Model="" clears the errors.

Additionally, opening the project in VS for Mac has no issues.

[akkgr]

I have the same issue in windiows 11 x64

[jtsom]

Agreed. Just did a simple test on Windows 10 and am seeing the same issue. It is not related to arm64.

Closing because I opened https://github.com/dotnet/razor-tooling/issues/6350 against the razor-tooling repo.
