Discovered that the webview required a commercial license in Avalonia 11, but is soon coming.

As of March 11, 2026, the Avalonia WebView is going open-source with Avalonia 12, and will be available to all developers without a commercial license.

There is a preview version of Avalonia. Altering the .csproj file allows us to build on that version and the WebView works great.
PackageReference Include="Avalonia" Version="12.0.0-preview2"

The AVLIC0001 error occurs because the Avalonia.Controls.WebView package was previously part of Avalonia Accelerate, a commercial offering.
However, the team has announced it will be fully open-sourced in the upcoming Avalonia 12 release.

When the new version releases, I'll come back to this project. 2026-03-21 I was able to figure out how to use the prerelease 12 version and build the app uing the Avalonia WebView
Everything seems to work great and this one uses the Opens Source license
