Product Information:
Version: 1.0.0-preview4-004233
Commit SHA-1 hash: 8cec61c6f7

Runtime Environment:
OS Name: Mac OS X
OS Version: 10.12
OS Platform: Darwin
RID: osx.10.11-x64
Base Path: /usr/local/share/dotnet/sdk/1.0.0-preview4-004233
VS Code version: 1.8.1
C# Extension version: 1.6.2

Steps to reproduce

1. Create a file containing multiple classes in a single namespace.
2. Move the cursor to the class name of the class to move
3. Press Command+.
4. Click on "Move type to classname.cs"

Expected behavior

• A new file is created containing the extracted class definition
• The class is removed from the original file

Actual behavior

Omnisharp won't do the refactoring and crashes, this is the output:
