Route template
A route template is a URL or URI path pattern containing fixed segments and parameters that determines which requests an endpoint matches.
ASP.NET Core in Action, 3e
A route template is a URL pattern containing fixed values and optional placeholders that determines which request URLs an endpoint matches.
- How it is used
- Maps request URLs to endpoints while extracting variable URL values for handlers.
- How deep it goes
- Works through literal, required, default, and optional segments, then identifies constraints and catch-all parameters without detailing their syntax here.
- Examples
- Uses a name-filtering minimal API, product URLs with defaults, file-based Razor Page routes, and combined controller attributes.
- What you can do after
- Build it from scratch with MapGet or customize it using Razor Page directives and controller route attributes.

A route template is a URL pattern containing segments and parameters that ASP.NET Core uses to match requests to endpoint actions.
- How it is used
- Routes HTTP GET requests to the appropriate controller action using URL segments and the request verb.
- How deep it goes
- Explains controller and segment matching with a single parameter, but defers detailed route-template rules to documentation.
- Examples
- Uses CatalogController, [HttpGet("{id}")], GetBook(int id), and the /catalog/1 request.
- What you can do after
- Apply it via ASP.NET Core attributes to distinguish collection and single-resource GET endpoints.
