[Visual Studio] Default language is used for cells instead of specified one

Describe the bug

If I want to use F# and I specify #!fsharp in each cell, then when I save and open a notebook #!fsharp disappears from cells but stays in a file and changes cell language. However, Visual Studio always executes cells with notebook default language but not with cell-specific. So that I need to put #!fsharp back again which is terrible!!!

By the way, if I leave the first line of the cell blank but put #!fsharp on the second line it stays 😁 in the UI.

Please complete the following:

Which version of .NET Interactive are you using? (In a notebook, run the #!about magic command. ):

• OS
  • Windows 11
• Frontend
  • Visual Studio

Thanks for the feedback! We're still in a Preview for ur Notebook Editor extension so not all functionality is available yet!

Language Selecting will be on our roadmap soon!
