# ASP0022: Route conflict detected between route handlers
@ -34,3 +34,9 @@ Do not suppress a warning from this rule.
## Notes
[ASP0023](xref:diagnostics/asp0023) warns on route conflicts in ASP.NET Core MVC apps, this analyzer warns on route conflicts in [minimal API](xref:fundamentals/apis) apps.
This analyzer is intentionally conservative about duplicate routes it reports to avoid false positives:
* The analyzer only reports duplicate routes declared in the same code block in a method. Duplicate routes in different branches of an `if` statement aren't reported because the analyzer can't statically determine which will be used at runtime.
* The analyzer only reports duplicate routes with known metadata. Unknown methods called on a route handler might add new metadata that is then used to customize how the route is matched.
