Field Not Found

Using an out of the box barebones MudBlazor setup and following the readme for ThemeManager.

MudBlazor, Version=6.0.6.0
Installed using dotnet add package

I get the following error:

crit: Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100] Unhandled exception rendering component: Field not found: .Material.Outlined Due to: Could not parse field signature 0a000069 due to: Could not resolve type with token 01000054 from typeref (expected class 'MudBlazor.Outlined' in assembly 'MudBlazor, Version=6.0.6.0, Culture=neutral, PublicKeyToken=null') assembly:MudBlazor, Version=6.0.6.0, Culture=neutral, PublicKeyToken=null type:MudBlazor.Outlined member:(null) System.MissingFieldException: Field not found: .Material.Outlined Due to: Could not parse field signature 0a000069 due to: Could not resolve type with token 01000054 from typeref (expected class 'MudBlazor.Outlined' in assembly 'MudBlazor, Version=6.0.6.0, Culture=neutral, PublicKeyToken=null') assembly:MudBlazor, Version=6.0.6.0, Culture=neutral, PublicKeyToken=null type:MudBlazor.Outlined member:(null) at Microsoft.AspNetCore.Components.ComponentBase.<.ctor>b__6_0(RenderTreeBuilder builder) at Microsoft.AspNetCore.Components.Rendering.ComponentState.RenderIntoBatch(RenderBatchBuilder batchBuilder, RenderFragment renderFragment, Exception& renderFragmentException) window.Module.s.printErr @ blazor.webassembly.js:1 bootstrap.min.css:1 Failed to load resource: the server responded with a status of 404 ()

Start with the README's ThemeManager setup and reproduce it in the reported barebones MudBlazor 6.0.6 application. Inspect the rendering entry point that produces the Material.Outlined field error and the bootstrap.min.css request; done means the setup renders without the MissingFieldException and the reported resource failure is resolved.
