But why are you? Unless it requires interfacing with a JS library or some JS operation on the DOM, the goal of a Blazor app is to write in C#, not JS. What's your JS code doing that it requires passing C# objects to it? (That said, Blazor supports JS Interop, see https://dev.to/rasheedmozaffar/intro-to-js-interop-in-blazor...)
