NLog Targets for Azure Storage

Package Name	NuGet	Description	Documentation
NLog.Extensions.AzureBlobStorage		Azure Blob Storage
NLog.Extensions.AzureDataTables		Azure Table Storage or Azure CosmosDb Tables
NLog.Extensions.AzureEventHub		Azure EventHubs
NLog.Extensions.AzureEventGrid		Azure Event Grid
NLog.Extensions.AzureQueueStorage		Azure Queue Storage
NLog.Extensions.AzureServiceBus		Azure Service Bus
NLog.Extensions.AzureAccessToken		Azure App Authentication Access Token for Managed Identity

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.
