Obfuscating Minimal APIs Can Silently Break Parameter Binding in .NET
A guide explains that obfuscating a .NET Minimal API can cause route and query values to bind incorrectly without any error. The framework's RequestDelegateFactory matches route tokens and query keys to handler parameters by their reflected names, which obfuscation can rename or strip. As a result, a request like GET /orders/42 may return the wrong record, such as order zero, while still responding with 200 OK. The article notes that shipped service DLLs can be decompiled to expose business logic and sensitive configuration, making obfuscation a common protection measure. It states that the piece will show how to protect the endpoint graph using Nebula.NET while keeping parameter binding functional.
