Blazor wasm observer undefined

[jongio]

Heads up that I tried this with Blazor wasm and am getting this error:

crit: Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]
      Unhandled exception rendering component: Could not find 'Observer.Initialize' ('Observer' was undefined).
      Error: Could not find 'Observer.Initialize' ('Observer' was undefined).

I resolved this by manually coping this file to wwwroot/js and referencing it from html head.
