@VBAndCs shared the following in another room:
"I offered to contribute to make a VB.NET Razor, but ASP team rejected the offer. I insisted to go forward alone, and thought I can simplfy the effort by separating VB code in a code-behind file, which made me remember that VB already has XML literals which can play as a built-in Razor! I made a VB.NET MVC Core App as a proof of concept here:
