I have found it's caused by PublishTrimmed, it's ok for everything is default, but if publish with trimmed and link, will get this error

@coader thanks for contacting us.

Thanks for contacting us. Could you provide a minimal repro project as a public github repository as well as the steps you use to publish the project so that we could help you?

Are you configuring the linker in any way yourself?

@coader can you please try out the latest 7.0 RC release. We know that the default project template works, so can't help you with this data. it should be something going on on your end.
If you find the culprit and you believe it's in Blazor, please file a new issue.
