SAML v2.0 for ASP.NET Core

Fully Compliant with the SAML v2.0 Specification

The SAML v2.0 component for ASP.NET Core is fully compliant with the OASIS Security Assertion Markup Language v2.0 specification.

It’s been tested successfully against ADFS, Azure AD, Google, Salesforce, Shibboleth and many more SAML offerings for interoperability.

Thousands of our clients have been using our award winning components in production systems throughout the world for many years.

SAML v2.0
SAML Profiles

All SAML v2.0 profiles are fully supported, acting as either the identity provider or service provider.

  • Web browser single sign-on (identity provider and service provider initiated)
  • Single logout
  • Artifact resolution
  • Identity provider discovery
  • Authentication, attribute and assertion query
  • Name identifier management and mapping
SAML Protocols

All SAML v2.0 protocols are fully supported.

  • Create, modify and access SAML protocol messages
  • Serialize SAML messages to and from XML
  • Generate and verify XML signatures (SHA-1 and SHA-256) on SAML messages
SAML Bindings

All SAML v2.0 bindings are fully supported.

  • HTTP Redirect
  • HTTP Artifact
  • SOAP
  • PAOS
SAML Assertions

SAML v2.0 assertions are fully supported.

  • Create, modify and access SAML assertions
  • Serialize SAML assertions to and from XML
  • Generate and verify XML signatures (SHA-1 and SHA-256) on SAML assertions
  • Encrypt and decrypt SAML assertions, attributes and identifiers
SAML Metadata

SAML v2.0 metadata is fully supported.

  • Create, modify and access all SAML metadata
  • Serialize to and from XML
  • Generate and verify XML signatures (SHA-1 and SHA-256) on SAML metadata
Platform Support

The SAML component supports all the .NET Core framework versions from v2.0 and above. This includes support for Visual Studio 2017. Both 32-bit and 64-bit versions of Windows Server 2008, 2012, 2016, as well as Windows 7, 8 and 10, are supported.


A high-level, configuration-driven API provides a very simple to use interface that hides the mechanics of SAML SSO. This makes it easy to add SSO functionality to your web application with just a few lines of code. Configuration changes, including adding support for additional partner identity providers or service providers, may be made with zero code changes.

SAML Middleware

The SAML authentication handler provides SSO support for service provider applications. The SAML middleware provides SSO support for identity provider applications. The middleware approach means even fewer lines of code.

Example Projects

Example ASP.NET Core projects, with full source code, are included. The examples demonstrate:

  • Acting as the identity provider (IdP)
  • Acting as the service provider (SP)
  • Identity provider initiated SSO
  • Service provider initiated SSO
  • Setting and retrieving SAML attributes
  • Logout

ASP.NET Core example projects are included demonstrating integration with:
