TS4022 Using RequestOptionsBase

[chieftn]

autorest output of file https://raw.githubusercontent.com/Azure/azure-rest-api-specs/master/specification/iothub/resource-manager/Microsoft.Devices/stable/2018-04-01/iothub.json with following specifications:

typescript.azure-arm: true
typescript:
output-folder: ./lib/
license-header: MICROSOFT_MIT_NO_VERSION
add-credentials: true
package-name: microsoft-azure-devices-iothub-controlplane
input-file: ./src/2018-04-01/iothub.json
package-version: 2018.04.01.01
generate-metadata: true

fails on tsc. "Receiving TS4022 -- has or is using private name 'RequestOptionsBase'." Manually corrected by exporting type RequestOptionsBase. Looking to understand if this is user error and / or correctable.

Loading AutoRest core 'C:\Users\rkessler.autorest@microsoft.azure_autorest-core@2.0.4277\node_modules@microsoft.azure\autorest-core\dist' (2.0.4277)
Loading AutoRest extension '@microsoft.azure/autorest.typescript' (~2.0.12->2.0.176)
Loading AutoRest extension '@microsoft.azure/autorest.modeler' (2.1.23->2.1.23)

New to tech -- so guidance appreciated.

Did this have a similar root cause as #76? Was it resolved by installing preview versions of autorest.typescript and ms-rest-js?

Please feel free to reopen if this is still a problem.

I've opened a request to fix issues like these in TypeScript by bringing declaration files to parity with language features. microsoft/TypeScript#35822
