Dotnet-new templates - cannot reslove service modal library but everything compiles

I’m using the dotnet-new react-spa template.
I’m not sure if it is vs2017 or SS that is failing to to reslove the ServiceInterface project in the web project’s startup.cs, it will compile though but have no intellisense.

I’ve tried cleaning the solution, deleting the obj folder with no luck. Is there somthing else I can try to get it working properly?

Thanks

After creating the template can you build it with:

nuget restore
dotnet build

If you can the project is valid and working as expected.
