 # Get started with Azure Blob Storage using F\#
 
 Azure Blob Storage is a service that stores unstructured data in the cloud as objects/blobs. Blob storage can store any type of text or binary data, such as a document, media file, or application installer. Blob storage is also referred to as object storage.

 For a conceptual overview of blob storage, see [the .NET guide for blob storage](/azure/storage/blobs/storage-quickstart-blobs-dotnet). For ease, these tutorials use [connection strings](/azure/storage/storage-configure-connection-string) to authenticate with Azure. For production applications, you should use Microsoft Entra ID with [managed identities](/entra/identity/managed-identities-azure-resources/) or the [Azure.Identity library](/dotnet/api/overview/azure/identity-readme) for enhanced security.
 
+> [!IMPORTANT]
+> This article uses the modern `Azure.Storage.Blobs` package. If you're updating from older code that used the deprecated `WindowsAzure.Storage` or `Microsoft.Azure.Storage.Blob` packages, you need to update your package references and namespace declarations. For migration guidance, see [Migrate to Azure.Storage.Blobs](/azure/storage/blobs/storage-quickstart-blobs-dotnet).

-> This article uses the standard Azure Storage Client Library for .NET. F# developers might consider the [FSharp.Azure.Blob](https://github.com/random82/FSharp.Azure.Blob) library, which provides a more idiomatic F# API for working with Azure Blob Storage. This community library offers idiomatic F# functions and patterns that make blob operations more natural in F#.
