blazor - Client MatBlazor matbutton could not find init (matblazor was undefined

Question

I am trying to add MatBlazor to my WASM client and I am getting the error:

blazor.webassembly.js:1 crit: Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]
      Unhandled exception rendering component: Could not find 'matBlazor.matButton.init' ('matBlazor' was undefined).
      Error: Could not find 'matBlazor.matButton.init' ('matBlazor' was undefined).

Microsoft.JSInterop.JSException: Could not find 'matBlazor.matButton.init' ('matBlazor' was undefined).

It was working on .NET Core, but started throwing an error on .Net 5.0.

I must be missing a step or something.

Suggestions?

The problem turned out to be I forgot to include the MatBlazor links in index.html
