PowerShell module for the management plane
It would be great if there was a supported PowerShell module for the CosmosDB management plane, in the same vein as the other Az modules. The Az PowerShell team have already done the vast majority of the work with their Autorest project so you'd just need to provide them with a Swagger/OpenAPI definition file and they can help you generate the majority of the code for it.
Work on PS cmdlets for Cosmos DB has now been started.
Will update as this progresses.
