How to use C# in the web browser using WebAssembly in an old ASP.NET MVC app

Hi there,

I'm maintaining an old ASP.Net MVC 4 application and I want to be able to use C# in the web browser using WebAssembly.

I can't use Blazor because the app is huge and I can't port it to Blazor.

I want to add new features using C# instead TypeScript/JavaScript.

Searching the web only show Blazor examples 

Can anyone help me?

Thank you.
