'Go to Symbol in Workspace' doesn't work unless an editor of the language is open

• VSCode Version: Code - Insiders 1.11.0-insider (d98a518, 2017-03-29T06:05:18.022Z)
• OS Version: Darwin x64 16.5.0

Go to Symbol in Workspace only seems to work if there is at least one editor of a particular language open. For example, in order to get workspace symbols in Typescript, I need to have at least 1 Typescript file open, same with C#. If I have no editors open then there no symbols are shown.

---

Steps to Reproduce:

1. Open a folder (Typescript, C#, a mix, etc)

2. With no editors open, do a symbol search for a known symbol

3. No results will be displayed

4. Open a folder with more than 1 language (Typescript & C# for instance)

5. Open a Typescript file

6. Do a symbol search for a known Typescript symbol

7. Results will be displayed

8. Do a symbol search for a known C# symbol

9. No results will be displayed

10. Open a C# file

11. Do a symbol search for a known C# symbol

12. Results will be displayed

Also in 1.10.2.

Thanks. This looks like a duplicate of #17022 on the TypeScript side

Try following up with the C# extension to see if this is something they can look into as well
