- We will be making only fixes related data integrity and security for 11.x.
- We will not be adding new storage service version support for this SDK.
- We will not be back porting fixes and features added to the current version to the versions in this repo
- We will not be making any changes to the performance characteristics of this SDK.
We have engineered a highly performant and scalable SDK with our V12 releases. We encourage all our customers to give it a try.
Microsoft Azure Storage SDK for .NET (11.2.3)
Server Version: 2019-07-07
The Microsoft Azure Storage SDK for .NET allows you to build Azure applications that take advantage of scalable cloud computing resources.
This repository contains the open source subset of the .NET SDK. For documentation of the complete Azure SDK, please see the Microsoft Azure .NET Developer Center.
Note: As of 10.0.0, the namespace has changed to Microsoft.Azure.Storage.Common, .Blob, .File, and .Queue. This is required for some SxS scenarios.
Note: As of 9.4.0, the Table service is not supported by this library.
Table support is being provided by CosmosDB.

The complete Microsoft Azure SDK can be downloaded from the Microsoft Azure Downloads Page and ships with support for building deployment packages, integrating with tooling, rich command line tooling, and more.
Please review Get started with Azure Storage if you are not familiar with Azure Storage.
For the best development experience, developers should use the official Microsoft NuGet packages for libraries. NuGet packages are regularly updated with new functionality and hotfixes.
- .NET Framework 4.5.2: As of September 2018, Storage Client Libraries for .NET supports primarily the desktop .NET Framework 4.5.2 release and above.
- Netstandard1.3: Storage Client Libraries for .NET are available to support Netstandard application development including Xamarin/UWP applications.
- Netstandard2.0: Storage Client Libraries for .NET are available to support Netstandard2.0 application development including Xamarin/UWP applications.
- Microsoft Azure Subscription: To call Microsoft Azure services, you need to first create an account. Sign up for a free trial or use your MSDN subscriber benefits.
- Hosting: To host your .NET code in Microsoft Azure, you additionally need to download the full Microsoft Azure SDK for .NET - which includes packaging, emulation, and deployment tools, or use Microsoft Azure Web Sites to deploy ASP.NET web applications.
- The Storage Client Libraries use the semantic versioning scheme
Use with the Azure Storage Emulator
- The Client Libraries use a particular Storage Service version. In order to use the Storage Client Libraries with the Storage Emulator, a corresponding minimum version of the Azure Storage Emulator must be used. Older versions of the Storage Emulator do not have the necessary code to successfully respond to new requests.
- Currently, the minimum version of the Azure Storage Emulator needed for this library is 5.3. If you encounter a
VersionNotSupportedByEmulator(400 Bad Request) error, please update the Storage Emulator.
Download & Install
The Storage Client Libraries ship with the Microsoft Azure SDK for .NET and also on NuGet. You'll find the latest version and hotfixes on NuGet via the
To get the source code of the SDK via git just type:
git clone git://github.com/Azure/azure-storage-net.git cd azure-storage-net
Please note that the minimum NuGet client version requirement has been updated to 2.12 in order to support multiple .NET Standard targets in the NuGet package.

Microsoft.Azure.Storage.Common package should be automatically entailed by NuGet.
The libraries depend on Newtonsoft.Json, which can be downloaded directly or referenced by your code project through Nuget.
The client-side encryption support depends on the KeyVault.Core package, which can be downloaded directly or referenced by your code project through Nuget.
FiddlerCore is required by:
This dependency is not included and must be downloaded from Telerik.
Tests for the client-side encryption support also depend on KeyVault.Extensions, which can be downloaded directly or referenced by your code project through Nuget.
OAuth testing requires the ActiveDirectory identity model also available via NuGet:
