Temp workaround for Cannot read property 'version' of null Issue #192:
Replace the contents of the server folder in your vscode Angular.ng-template-0.1.7 extension with the files out of the repo:
https://github.com/smasala/angular-language-service-0.17.patch
You'll usually find your extension folder in Windows under: C:\Users[username].vscode\extensions\Angular.ng-template-0.1.7
