OAuth has been around for more than 10 years now, and has become the standard protocol for token-based security. Like every popular technology that has been growing with its requirements, there are some things which work really well, and some that did not quite stand the test of time.
2025 is an excellent year to either start learning OAuth & OpenID Connect from scratch or give them a refresher. With the upcoming OAuth 2.1 protocol revision, the protocol has been streamlined and simplified and the specification has been updated to meet modern application and security requirements. At the same time ASP.NET and .NET in general has excellent support for all the moving parts needed to implement an OAuth-based security system.
This full day workshop teaches you all the OAuth you need utilizing the most common and practical techniques and libraries in the .NET ecosystem. Besides looking at built-in features of (ASP).NET, we will use popular frameworks like IdentityModel and IdentityServer, and we will learn how to use them to secure native/desktop and web applications as well as SPAs, Blazor WASM applications, APIs and daemons.
