Project
Enterprise Bot Template

Description
When verifying the structure of the Cognitive Models of LUIS and QnA Maker between C# and TypeScript, we found differences between them.
Each one should have the same structure.

To Reproduce

1. Open AI/templates/Enterprise-Template/src/typescript/cognitiveModels and AI/templates/Enterprise-Template/src/csharp/EnterpriseBotSample/CognitiveModels.
2. Compare them and look the differences.

Expected behavior
Each of them should have the same structure.
