Can't find minimal endpoint named via WithName() when using Results.CreatedAt #35314
Description
Calling .WithName("ApiName") on a minimal endpoint API does not add a RouteNameMetadata with specified name to the endpoint's metadata, just an EndpointNameMetadata. This means URLs can't be generated for the endpoint by IUrlHelper using route values, which includes the Results.CreatedAtRoute method.
We should update .WithName(string name) to also add the RouteNameMetadata.
Repro code:
app.MapGet("/todos/{id}", async (int id, TodoDb db) =>
{
return await db.Todos.FindAsync(id)
is Todo todo
? Results.Ok(todo)
: Results.NotFound();
})
.WithName("GetTodoById")
.Produces<Todo>()
.Produces(StatusCodes.Status404NotFound);
app.MapPost("/todos", async (Todo todo, TodoDb db) =>
{
db.Todos.Add(todo);
await db.SaveChangesAsync();
return Results.CreatedAtRoute("GetTodoById", new { todo.Id } , todo);
})
.WithName("AddTodo")
.ProducesValidationProblem()
.Produces<Todo>(StatusCodes.Status201Created);
