[VS] Guests do not get C#/VB intellisense in CSHTML/VBHTML files

[Chuxel]

NOTE: Live Share currently has full intellisense for C#, JS, and TS files. See platform support for up-to-date information on which languages support features like intellisense.

While CSHTML does not have deep intellisense support in VS Code, Visual Studio does. Unfortunately, right now CSHTML's backing implementation for inline C# does not work with VS Live Share and this is a full feature needed to implement. This is was tagged as a bug given it's behavior, but it is effectively a full feature. While #51 is resolved with the latest VS preview bits, full intellisense is not available.

Product and Version [VS/VSCode]: Latest Visual Studio 2017 Update 6 (15.6)
OS Version [macOS/Windows]: Windows 10 64-bit
Live Share Extension Version: 0.1.0.217
Target Platform or Language [e.g. Node.js]: CSHML or VBHTML in an ASP.NET project
Steps to Reproduce / Scenario:

1. [Host] Create a new .NET MVC Project (File > New Project)
2. [Host] Share
3. [Host] Open Views/_ViewImports.cshtml
4. [Guest] Sign in and join
5. [Guest] Move to this same file (which should automatically happen)
6. [Guest] Hover over "Models" on line 2

Expected: Both Host and Guest see the same thing
Actual: No intellisense for the guest

@benprime cs/vbhtml support is only available from 15.9 Preview 5 going forward. Could you update your Visual Studio and let us know if you're still encountering this issue?
