Blazor wasm new project not recognizing Radzen Nuget Pkg

If I create a new Blazor wasm (client-side) project with Radzen, I'm not able to compile.

  1. Create a new Blazor wasm project
  2. Add a nuget pkg (Radzen.Blazor)
  3. Add this line to the index.html file
  4. Add a @using Radzen.Blazor to the _Imports.razor file

I get a red squiggly under the "@using Radzen.Blazor" statement and a compile time error saying that the namespace Radzen couldn't be found. From the sparse doco I've found on Radzen wasm, I thought that these were the only steps.


VS 2019 core 3.1-preview 2.19528
Radzen.Blazor 2.5.7 
.net standard lib 2.0.3
