Visual Studio editor - extend selection to the next larger code block?

In ReSharper, this is extend selection and the shortcut is CTRL-W. Not sure of a non-ReSharper solution.

Visual Studio 2017 15.5.2 appears to have this feature built-in after it was first hinted at in a Visual Studio 2017 Preview blog post (see section "Smart Code Editor").

Invoking it can be done by going to Edit > Advanced > Expand Selection or by binding the Edit.ExpandSelection command to Ctrl+W (actually the new default if you start without any previous keybindings).

Shrinking / contracting the selection is possible as well, look for Edit > Advanced > Contract Selection or the Edit.ContractSelection command (default Ctrl+Shift+W).
