@ -57,7 +57,7 @@ The primary inputs to `GetVirtualPath` are:
* [VirtualPathContext.Values](xref:Microsoft.AspNetCore.Routing.VirtualPathContext.Values*)
* [VirtualPathContext.AmbientValues](xref:Microsoft.AspNetCore.Routing.VirtualPathContext.AmbientValues*)
Routes primarily use the route values provided by the `Values` and `AmbientValues` to decide where it's possible to generate a URL and what values to include. The `AmbientValues` are the set of route values that were produced from matching the current request with the routing system. In contrast, `Values` are the route values that specify how to generate the desired URL for the current operation. The `HttpContext` is provided in case a route needs to obtain services or additional data associated with the current context.

> [!TIP]
> Think of [VirtualPathContext.Values](xref:Microsoft.AspNetCore.Routing.VirtualPathContext.Values*) as being a set of overrides for the [VirtualPathContext.AmbientValues](xref:Microsoft.AspNetCore.Routing.VirtualPathContext.AmbientValues*). URL generation attempts to reuse route values from the current request to make it easy to generate URLs for links using the same route or route values.
