Windows Azure SDK for .NET

The Windows Azure SDK for .NET allows you to build Windows 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 SDK, please see the Windows Azure .NET Developer Center.

Getting started

The complete Windows Azure SDK can be downloaded from the Windows Azure Downloads Page and ships with support for building deployment packages, integrating with tooling, rich command line tooling, and more.

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.

Target Frameworks

  • .NET Framework 4.5 and newer
  • .NET Framework 4.0
  • Storage Libraries are available for Windows 8 for Windows Store development as well as Windows Phone 8

As of 10/2013, SDK 2.2 supports targeting only .NET Framework 4.0 and newer.

Need support for previous versions of .NET such as 3.5? Version 2.1 of the Windows Azure SDK for .NET supports this version and can still be used today.


  • Windows Azure Subscription: To call Windows 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 Windows Azure, you additionally need to download the full Windows Azure SDK for .NET - which includes packaging, emulation, and deployment tools, or use Windows Azure Web Sites to deploy ASP.NET web applications.

Need Help?

Be sure to check out the Windows Azure Developer Forums on MSDN if you have trouble with the provided code or use StackOverflow.

Collaborate & Contribute

We gladly accept community contributions.

Storage Client Library for .NET 4, Windows 8, and Windows Phone 8 (

The Storage Client Library ships with the Windows Azure SDK for .NET and also on NuGet. You'll find the latest version and hotfixes on NuGet via the WindowsAzure.Storage package. You can read about the 2.1 release on the storage team blog post.

Please note that Windows 8 and Windows Phone 8 libraries are CTP (Community Technology Preview) releases.

Download & Install

Via Git

To get the source code of the SDK via git just type:

git clone git://
cd azure-sdk-for-net

Via NuGet

To get the binaries of this library as distributed by Microsoft, ready for use within your project you can also have them installed by the .NET package manager NuGet.

Install-Package WindowsAzure.Storage



This version depends on three libraries (collectively referred to as ODataLib), which are resolved through the ODataLib (version 5.2.0) packages available through NuGet and not the WCF Data Services installer which currently contains 5.0.0 versions.

The ODataLib libraries can be downloaded directly or referenced by your code project through NuGet.

The specific ODataLib packages are:

Test Dependencies

FiddlerCore is required by:

  • Test\Unit\FaultInjection\HttpMangler
  • Test\Unit\FaultInjection\XStoreMangler
  • Test\Unit\DotNet40

This dependency is not included and must be downloaded from

Once installed:

  • Copy FiddlerCore.dll \azure-sdk-for-net\microsoft-azure-api\Services\Storage\Test\Unit\FaultInjection\Dependencies\DotNet2
  • Copy FiddlerCore4.dll to azure-sdk-for-net\microsoft-azure-api\Services\Storage\Test\Unit\FaultInjection\Dependencies\DotNet4

Code Samples

Note: How-Tos focused around accomplishing specific tasks are available on the Windows Azure .NET Developer Center.

Creating a Table

First, include the classes you need (in this case we'll include the Storage and Table and further demonstrate creating a table):

using Microsoft.WindowsAzure.Storage;
using Microsoft.WindowsAzure.Storage.Table;

To perform an operation on any Windows Azure resource you will first instantiate a client which allows performing actions on it. The resource is known as an entity. To do so for Table you also have to authenticate your request:

var storageAccount = CloudStorageAccount.Parse(
var tableClient = storageAccount.CreateCloudTableClient();

Now, to create a table entity using the client:

CloudTable peopleTable = tableClient.GetTableReference("people");

Windows Azure Management Libraries

Automate, configure and command your Windows Azure deployments, infrastructure and accounts with the Windows Azure Management Libraries.

Preview: At this time the Windows Azure Management Libraries are in the preview state as the teams gather feedback and prepare for the initial release. Please enjoy using the libraries and source in any capacity, but understand that there may be breaking changes with the 1.0 release.

Download & Install

Via Git

To get the source code of the SDK via git just type:

git clone git://
cd azure-sdk-for-net\libraries

Via NuGet

Official binaries are distributed by Microsoft and available using the .NET package manager NuGet.

To get all of the management libraries setup in your project:

Install-Package Microsoft.WindowsAzure.Management.Libraries -IncludePrerelease

You can also install just the management library for a service of interest. To deploy a virtual machine to the cloud, the Microsoft.WindowsAzure.Management.Compute package can be used, for example.

Code Samples

This code would result with a list of the regions in the Windows Azure fabric. The location object provided in the result provides properties to define which assets are supported by each region.

using (ManagementClient client = CloudContext.Clients.CreateManagementClient(Credentials))
    var result = await client.Locations.ListAsync();
    var locations = result.Locations;
    foreach (var location in locations)
        Console.WriteLine("Location: {0}", location.Name);

        foreach (var feature in location.AvailableServices)

To create a storage account,The code below will create a storage account in the West US region.

var storageAccountName = "mystorageaccount";

using (StorageManagementClient client =
    await client.StorageAccounts.CreateAsync(
        new StorageAccountCreateParameters
            ServiceName = storageAccountName,
            Location = LocationNames.WestUS

The code below will obtain the storage account keys to construct a connection string on the fly.

var storageAccountName = "mystorageaccount";

using (StorageManagementClient client =
    var keys = await

    string connectionString = string.Format(
        storageAccountName, keys.SecondaryKey);

    return connectionString;

The following code will create a new (empty) Cloud Service in the Windows Azure fabric.

var cloudServiceName = "MyCloudService";

using (ComputeManagementClient client =
    await client.HostedServices.CreateAsync(
        new HostedServiceCreateParameters
            ServiceName = cloudServiceName,
            Location = LocationNames.WestUS

Once a storage account has been created, the Windows Storage SDK can be used to upload .CSPKG files into the storage account. Then, the cloud service could be deployed. The code below demonstrates this functionality.

var blobs = CloudStorageAccount.Parse(storageConnectionString).CreateCloudBlobClient();

var container = blobs.GetContainerReference("deployments");

await container.CreateIfNotExistsAsync();

await container.SetPermissionsAsync(
    new BlobContainerPermissions()
        PublicAccess = BlobContainerPublicAccessType.Container

var blob = container.GetBlockBlobReference("MyCloudService.cspkg");

await blob.UploadFromFileAsync("MyCloudService.cspkg", FileMode.Open);

var cloudServiceName = "MyCloudService";

using (ComputeManagementClient client =
    await client.Deployments.CreateAsync(cloudServiceName,
        new DeploymentCreateParameters
            Name = cloudServiceName + "Prod",
            Label = cloudServiceName + "Prod",
            PackageUri = blob.Uri,
            Configuration = File.ReadAllText("MyCloudService.cscfg"),
            StartDeployment = true
