How to hide part of code in Visual Studio Code?

Question

Visual Studio Code

Previously, I had [+] next to the methods in my code, I write in C #, by clicking on them, the methods were hidden (one name remained), it’s convenient, but now they are gone and I can’t collapse, I read in the search that this action can be performed by selecting the text and by pressing Ctrl+M and open Ctrl+H, but nothing happens...
Tell me how to return these [+] or how to hide pieces of code?

Answer 1

Try to enclose pieces of code in

#region Свойства
 public string Name{get;set;}
#endregion
