Support SLA

MSAL.NET became Generally Available with MSAL.NET 3.0.8. Since MSAL.NET moved to version 4:

  • Major versions are supported for twelve months after the release of the next major version.
  • Minor versions older than N-1 are not supported.

Note Minor versions include bug fixes or features with non-breaking (additive) API changes. It is expected that applications using the library can upgrade through the IDE or CLI with no friction. We will not patch old minor versions of the library. When opening new issues, please confirm that you are using the latest minor version.

Community help and support

We use Stack Overflow with the community to provide support. We highly recommend you ask your questions on Stack Overflow first and browse existing issues to see if someone has asked your question before.

If you find a bug or have a feature request, please raise the issue on GitHub Issues.

Contribute

We welcome contributions and feedback. You can fork and clone the repo and start contributing now. Read our Contribution Guide for more information.

This project has adopted the Microsoft Open Source Code of Conduct. For more information see the Code of Conduct FAQ or contact opencode@microsoft.com with any additional questions or comments.

Security library

This library controls how users sign-in and access services. We recommend you always take the latest version of our library in your app when possible. We use semantic versioning so you can control the risk associated with updating your app. As an example, always downloading the latest minor version number (e.g. x.y.z) ensures you get the latest security and feature enhancements but our API surface remains the same. You can always see the latest version and release notes under the Releases tab of GitHub.

Security reporting

If you find a security issue with our libraries or services please report it to secure@microsoft.com in as much detail as possible. Your submission may be eligible for a bounty through the Microsoft Bug Bounty program. Please do not post security issues to GitHub Issues or any other public site. We will contact you shortly after receiving the information. We encourage you to get notifications of when security incidents occur by visiting the Microsoft Technical Security Notifications page and subscribing to Security Advisory Alerts.

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 in the repository. There are also some features in the software that may enable you and Microsoft to collect data from users of your applications. If you use these features, you must comply with applicable law, including providing appropriate notices to users of your applications together with a copy of Microsoft's privacy statement. Our privacy statement is located at https://go.microsoft.com/fwlink/?LinkID=824704. You can learn more about data collection and use in the help documentation and our privacy statement.
