Initially all NLog targets was bundled into a single nuget-package called NLog.Extensions.AzureStorage. But Microsoft decided to discontinue WindowsAzure.Storage and split into multiple parts. Later Microsoft also decided to discontinue Microsoft.Azure.DocumentDB and so NLog.Extensions.AzureCosmosTable also became deprecated.
