Azure SDK for .NET

This repository is for active development of the Azure SDK for .NET. For consumers of the SDK we recommend visiting our public developer docs or our versioned developer docs.

Getting started

To get started with a library, see the README.md file located in the library's project folder. You can find these library folders grouped by service in the /sdk directory.

For tutorials, samples, quick starts, and other documentation, go to Azure for .NET Developers.

Packages available

Each service might have a number of libraries available from each of the following categories:

• Client - New Releases
• Client - Previous Versions
• Management - New Releases
• Management - Previous Versions

Client: New Releases

New wave of packages that we are announcing as GA and several that are currently releasing in preview. These libraries follow the Azure SDK Design Guidelines for .NET and share a number of core features such as HTTP retries, logging, transport protocols, authentication protocols, etc., so that once you learn how to use these features in one client library, you will know how to use them in other client libraries. You can learn about these shared features at Azure.Core.

These new client libraries can be identified by the naming used for their folder, package, and namespace. Each will start with Azure, followed by the service category, and then the name of the service. For example Azure.Storage.Blobs.

For a complete list of available packages, please see the latest available packages page.

NOTE: If you need to ensure your code is ready for production we strongly recommend using one of the stable, non-preview libraries.

Client: Previous Versions

Last stable versions of packages that are production-ready. These libraries provide similar functionalities to the preview packages, as they allow you to use and consume existing resources and interact with them, for example: upload a storage blob. Stable library directories typically contain 'Microsoft.Azure' in their names, e.g. 'Microsoft.Azure.KeyVault'. They might not implement the guidelines or have the same feature set as the November releases. They do however offer wider coverage of services.

Management: New Releases

A new set of management libraries that follow the Azure SDK Design Guidelines for .NET and based on Azure.Core libraries are now in Public Preview. These new libraries provide a number of core capabilities that are shared amongst all Azure SDKs, including the intuitive Azure Identity library, an HTTP Pipeline with custom policies, error-handling, distributed tracing, and much more. You can find the list of new packages on this page.

To get started with these new libraries, please see the quickstart guide here. These new libraries can be identified by namespaces that start with Azure.ResourceManager, e.g. Azure.ResourceManager.Network

NOTE: If you need to ensure your code is ready for production use one of the stable, non-preview libraries.

Management: Previous Versions

For a complete list of management libraries which enable you to provision and manage Azure resources, please check here. They might not have the same feature set as the new releases but they do offer wider coverage of services. Previous versions of management libraries can be identified by namespaces that start with Microsoft.Azure.Management, e.g. Microsoft.Azure.Management.Network

Documentation and code samples for these libraries can be found here.

Data Collection

The software may collect information about you and your use of the software and send it to Microsoft. Microsoft may use this information to provide services and improve our products and services. You may turn off the telemetry as described below. You can learn more about data collection and use in the help documentation and Microsoft’s privacy statement. For more information on the data collected by the Azure SDK, please visit the Telemetry Guidelines page.

Telemetry Configuration

Telemetry collection is on by default.

NOTE: HttpClient may set default user agent headers as part of the .NET platform behavior. This value does not contain any Azure SDK telemetry information.

You can disable telemetry when creating a client by setting the IsTelemetryEnabled property in the diagnostics options:

Uri serviceEndpoint = new Uri("https://example.contoso.com");
TokenCredential credential = new DefaultAzureCredential();

SampleClientOptions clientOptions = new SampleClientOptions()
{
    Diagnostics = { IsTelemetryEnabled = false }
};

SampleClient client = new SampleClient(serviceEndpoint, credential, clientOptions);

Alternatively, you can disable telemetry globally by setting the AZURE_TELEMETRY_DISABLED environment variable to true before creating any clients.
