Error generating Rest API client code in VS

Dear team,

While trying to add a **REST API client** in a universal app I get the following error :

[Fatal]Error generating client model: Found operation objects with **duplicate operationId 'GetInvoiceType'**. OperationId must be unique among all operations described in the API.
Exception: There was an error during code generation when trying to add a client for the REST API

repro steps: start new UWP (project type is not of great importance I think), add REST API client

BR,

Reproduce this by creating a new UWP project in Visual Studio and using Add REST API client with the API that contains duplicate operationId 'GetInvoiceType'. Start by tracing the client-generation failure and identify the relevant API definition or generation entry point; done means the REST API client generates without the duplicate-operation error.
