Microsoft Identity Web

Microsoft Identity Web is a library which contains a set of reusable classes used in conjunction with ASP.NET Core for integrating with the Microsoft identity platform (formerly Azure AD v2.0 endpoint) and AAD B2C.

This library is for specific usage with:

• Web applications, which sign in users and, optionally, call web APIs
• Protected web APIs, which optionally call protected downstream web APIs

Release notes, roadmap and SLA

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.
• Code samples are available for web app samples and web API samples

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.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 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.

Prerequisites

• Install .NET 10 preview SDK from https://dotnet.microsoft.com/download/dotnet/10.0

Building with .NET 10 Preview

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.
