-The "webfrontend" project resource uses <xref:Aspire.Hosting.ResourceBuilderExtensions.WithReference%2A> to add a dependency on the "cache" container resource. These dependencies can represent connection strings or [service discovery](../service-discovery/overview.md) information. In the preceding example, an environment variable is _injected_ into the "webfronend" resource with the name `ConnectionStrings__cache`. This environment variable contains a connection string that the `webfrontend` uses to connect to Redis via the [.NET Aspire Redis integration](../caching/stackexchange-redis-caching-overview.md), for example, `ConnectionStrings__cache="localhost:62354"`.
