PowerShell build error due to variable naming

[wwendyc]

After AutoRest generation based on my team’s Swagger spec, the below build error occurs when running build-module.ps1

D:\a\1\s\src\ProviderHub\generated\api\Models\Api20201120\ProviderRegistrationPropertiesProviderHubMetadata.cs(6,9): error CS0535: 'ProviderRegistrationPropertiesProviderHubMetadata' does not implement interface member 'IProviderHubMetadata.ThirdPartyProviderAuthorizationAuthorizations' [D:\a\1\s\src\ProviderHub\Az.ProviderHub.csproj]
D:\a\1\s\src\ProviderHub\generated\api\Models\Api20201120\ProviderRegistrationPropertiesProviderHubMetadata.cs(7,9): error CS0738: 'ProviderRegistrationPropertiesProviderHubMetadata' does not implement interface member 'IProviderHubMetadataInternal.ThirdPartyProviderAuthorization'. 'ProviderRegistrationPropertiesProviderHubMetadata.ThirdPartyProviderAuthorization' cannot implement 'IProviderHubMetadataInternal.ThirdPartyProviderAuthorization' because it does not have the matching return type of 'IThirdPartyProviderAuthorization'. [D:\a\1\s\src\ProviderHub\Az.ProviderHub.csproj]
D:\a\1\s\src\ProviderHub\generated\api\Models\Api20201120\ProviderRegistrationPropertiesProviderHubMetadata.cs(7,9): error CS0535: 'ProviderRegistrationPropertiesProviderHubMetadata' does not implement interface member 'IProviderHubMetadataInternal.ThirdPartyProviderAuthorizationAuthorizations' [D:\a\1\s\src\ProviderHub\Az.ProviderHub.csproj]

Here is the link to the specific property in our Swagger:
https://github.com/Azure/azure-rest-api-specs/blob/master/specification/providerhub/resource-manager/Microsoft.ProviderHub/stable/2020-11-20/providerhub.json#L3629
We have another property called “providerAuthorizations” and I noticed that if I change this field from “authorizations” to something other than authorization/providerAuthorizations there is no error during the build.

The issue should have been fixed in autorest.powershell v4.

@dolauli Where is v4?

I write a normal script like below

npm install -g "autorest"
autorest configuration.yaml

and autorest use version 3 like below

I try to specify version be below code (as I learn from Azure/autorest#2976)

use:
  - '@autorest/[email protected]'

But I got below errors

The default version of @autorest/powershell has been bumped from 2.1+ to 3.0+.
 > If you still want to use 2.1+ version, please specify it with --use:@autorest/[email protected].{x}, e.g 2.1.401.

error   |   Error: Unable to resolve package '@autorest/[email protected]'.

I found some workaround about that, with specific version in configuraiton.yaml as you can see in #1246 , But Did you know exist any better approach to using versoin 4.x?

thanks
