Two things: 1. Call hierarchy is available only in Pro and above 2. Call hierarchy is available only in C #
Assuming these two things are true for you, it looks like you might have a binding problem or something else going on. Open "Tools" → "Options" → "Keyboard" and enter "View.CallHierarchy" in the "Show Commands Containing" text box. See what is listed in the Shortcuts for the selected command drop-down list.
