This package enables ASP.NET Core web apps and web APIs to use the Microsoft identity platform (formerly Azure AD v2.0).
This package is specifically used for web applications, which sign-in users and call Microsoft Graph, and for protected web APIs
that call Microsoft Graph. Works specifically with MS Graph SDK v5 and above. For MS Graph SDK v4 support, please use Microsoft.Identity.Web.MicrosoftGraph.

Release notes and roadmap
The Microsoft Identity Web roadmap is available from Roadmap in the Wiki pages, along with release notes.
Support SLA
Major versions are supported for twelve months after the release of the next major version.
Minor versions older than N-1 are not supported.
Minor versions are bugfixes or features with non-breaking (additive) API changes. It is expected apps can upgrade. Therefore, we will not patch old minor versions of the library. You should also confirm, in issue repros, that you are using the latest minor version before the Microsoft Identity Web team spends time investigating an issue.
Using Microsoft Identity Web
The conceptual documentation is currently available from the Wiki pages.
If you find a bug or have a feature or documentation request, please raise the issue on GitHub Issues.
We use Stack Overflow with the community to provide support, using the tags web-app, web-api, asp.net-core, microsoft-identity-web. We highly recommend you ask your questions on Stack Overflow first and browse existing issues to see if someone has asked your question before.
We enthusiastically welcome contributions and feedback. You can clone the repo and start contributing now. Read our Contribution Guide for more information.
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.x) 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 with as much detail as possible. Your submission may be eligible for a bounty through the Microsoft Bounty program. Please do not post security issues to GitHub Issues or any other public site. We will contact you shortly upon receiving the information. We encourage you to get notifications of when security incidents occur by visiting this page and subscribing to Security Advisory Alerts.
Building with .NET Preview Versions
Microsoft Identity Web supports building and testing with .NET preview versions using the TargetNetNext conditional compilation flag. This enables early testing and compatibility validation with the latest .NET preview releases.
To build the solution with .NET 10 preview support:
# Build with .NET 10 preview targets included
dotnet build Microsoft.Identity.Web.sln -p:TargetNetNext=True
# Or using MSBuild
msbuild Microsoft.Identity.Web.sln -p:TargetNetNext=True
You can also set the TargetNetNext environment variable on your machine with the value True.
Testing with .NET 10 Preview
To run tests targeting .NET 10 preview:
# Run tests with .NET 10 preview (conditional)
dotnet test Microsoft.Identity.Web.sln -f net10.0 -p:TargetNetNext=True
Note: .NET 10 preview support is conditional and requires setting TargetNetNext=True during build/test operations. This ensures compatibility with the latest preview versions while maintaining stability for production builds.
