The Story

**Contract-first Minimal APIs and Authentication/Authorization in ASP.NET Core.** Join us for two talks on ASP.NET Core. Renato Golia shares his experiences with Contract-first REST APIs with ASP.NET Core Minimal APIs and Anders Abel gives an overview of Authentication and Authorization in ASP.NET Core. **AGENDA** 17.30 Doors open 17.45 Session 1 - Renato Golia 18.30 Food and drinks 19.00 Session 2 - Anders Abel 20.00 Questions, Discussions and Mingle 20.30 Event ends **Contract-first REST APIs with ASP.NET Core Minimal APIs** Most ASP.NET Core APIs treat OpenAPI as documentation generated from the implementation. That works well at first, but it can make the contract feel secondary: clients discover breaking changes late, API reviews happen after the code is written, and documentation can drift from what consumers expect. In this session, we’ll look at a contract-first approach for building REST APIs with ASP.NET Core Minimal APIs, where the OpenAPI document becomes the source of truth rather than a by-product. We’ll explore what this changes in the development workflow, how strongly typed contracts can help keep implementation and specification aligned, and what trade-offs come with moving the API contract to the center of the design process. We’ll also compare this approach with the more common code-first style in .NET. Based on the experience of hundreds of customer projects Anders shares his recommendations for authentication and authorization with Asp.Net Core. **ASP.NET Core Authentication and Authorization - the Key Concepts** This is an introductory session that will show the basic concepts of Authentication and Authorization in Asp.Net Core and how they interact. Topics that are covered include: * Authentication Schemes: Configuration and working with multiple schemes. * Asp.Net Identity: When to use it and how it affects the schemes used. * Data Protection: How it is used behind the scenes and the configuration required before going to production.
