thanks for your report.
I find ɵsetClassMetadata in Angular is to support Ivy compatible mode?(source code -> package -> ivy build?) and this package is not compatible previous code(currently only source code-> static inject). Can you tell me where to use it?
The Version variable does not exist. Because it is not synchronized with 'angular', it is an independent update
Is Injectable means @Injectable decorator?I think it will work. Because this is a basic function. You can give me a demo if you have some bug.
