Generate auto roperty for model from cshtml file removes Refactoring menu.

RS 9

1. I have a partial view template and class something like below:
class Foo {
}
@model Foo
@{
  var foo = Foo.IsFoo
}

2. IsFoo is red so I choose via RS to generate a property via Alt+Enter
3. Now I want to make that IsFoo with backing field, hitting Alt+Enter on the generated property in Foo.cs only displays some "weird"  "Enter Action NAme" menu.
4. I write a dummy class below class Foo in same file like so
class FooBar {
  public inte GiveBackMyQuickFix {get;set;}
}
5. I now can select the property and use see the "normal" menu with "To property with backing field".

What's up with that?
