Questison

please answer the following questions. put x inside [ ] (e.g. [x])

What inside?

• Bug Fixes?
• New Features? (generated code)
• Documentation? (readme basic example)

Is pull request totally generated from swagger file?

• Yes.
• No, part of it is auto-generated. (I include other changes necessaries to work with the new generated code)

Backward compatibility break?

• Yes. Pull request breaks backward compatibility! (I left the old code intact and put generated code in another folder and another main class, so "backward compatibility" doesn't break)

Learn more about backward compatibility.

Sorry. I started from master at the beginning, so I made a rebase to "dev" branch to change the parent branch.

@ali-hamud could you check it please ?

Hi Diego,
Thank you for the pull request.
As we got more requests to update this, we will give it higher priority. I"ll look into it next week.

Hi,
Code looks OK except of the Import code.
Import code is still using azure Workspace collections and didn't moved to the new pattern.
Do you want me to take it from here?

[ali-hamud]

Another thing:
calling super from constructor throws this error:
Class constructor PowerBIClient cannot be invoked without 'new'

I think This is related to changes of versions in package.json and typings file.

[diego-d5000]
