@isra-fel I tried running the following, but it just hangs there forever

Start-AutoRestCodeGeneration -ResourceProvider "apimanagement/resource-manager" -AutoRestVersion "latest" -ConfigFileTag "package-2019-01" -SdkRepoRootPath "D:\git\azure-sdk-for-net"

Last statement

cmd.exe /c autorest.cmd https://github.com/Azure/azure-rest-api-specs/blob/master/specification/apimanagement/resource-manager/readme.md --csharp --version=latest --refle
ct-api-versions --tag=package-2019-01 --csharp-sdks-folder=D:\git\azure-sdk-for-net
