+# Creating an application with a .NET60 code sample
+
+**Note:** The .NET60 code sample uses the **8081** HTTP port.
+
+Before you begin creating an application with this `devfile` code sample, it's helpful to understand the relationship between the `devfile` and `Dockerfile` and how they contribute to your build. You can find these files at the following URLs:
+
+* [.NET60 `devfile.yaml`](https://github.com/devfile-samples/devfile-sample-dotnet60-basic/blob/main/devfile.yaml)
+* [.NET60 `Dockerfile`](https://github.com/devfile-samples/devfile-sample-dotnet60-basic/blob/main/docker/Dockerfile)
+
+1. The `devfile.yaml` file has an [`image-build` component](https://github.com/devfile-samples/devfile-sample-dotnet60-basic/blob/main/devfile.yaml#L40-L46) that points to your `Dockerfile`.
+2. The [`docker/Dockerfile`](https://github.com/devfile-samples/devfile-sample-dotnet60-basic/blob/main/docker/Dockerfile) contains the instructions you need to build the code sample as a container image.
+3. The `devfile.yaml` [`kubernetes-deploy` component](https://github.com/devfile-samples/devfile-sample-dotnet60-basic/blob/main/devfile.yaml#L47-L59) and [`kubernetes-service` component](https://github.com/devfile-samples/devfile-sample-dotnet60-basic/blob/main/devfile.yaml#L60-L67) points to a `deployment.yaml` file and `service.yaml`that contains instructions for deploying the built container image.
+4. The `devfile.yaml` [`deploy` command](https://github.com/devfile-samples/devfile-sample-dotnet60-basic/blob/main/devfile.yaml#L94-L102) completes the [outerloop](https://devfile.io/docs/2.2.0/innerloop-vs-outerloop) deployment phase by pointing to the `image-build` and `kubernetes-deploy` components to create your application.
