  "Create Bindable Property": {
    "scope": "csharp",
    "prefix": "propp",
    "body": [
      "private ${1:Type} _${3:${2/(.*)/${1:/camelcase}/}};",
      "public ${1:Type} ${2:Name}",
      "{",
      "   get { return _$3; }",
      "   set { SetProperty(ref _$3, value); }",
      ,
      "}"
    ],
    "description": "Create a property, with a backing field, that depends on BindableBase."
  }

About ${3:...}

• ${2/(.*)/${1:/camelcase}/}: This part is a combination of regular expression and replacement pattern. It generates the name of the backing field based on the value of ${2:Name}.
• (.*): This is a regular expression capture group. It captures the property name (Name) entered by the user.
• ${1:/camelcase}: This is a replacement pattern for converting the captured string to camel case. ${1:...} references the captured value, and :camelcase instructs camel case conversion.
