+# Cloud Run - .NET Demo
+
+This walkthrough creates a basic [ASP.NET MVC Core](https://docs.microsoft.com/en-us/aspnet/core/tutorials/first-mvc-app/start-mvc) web application.
+
+## Prerequisites
+
+To create and build the application, you'll need
+
+* [.NET 8 SDK](https://dotnet.microsoft.com/en-us/download/dotnet/8.0)
+* [Google Cloud account and project](https://cloud.google.com/resource-manager/docs/creating-managing-projects)
+
+## Build a Linux Docker image
+1. Open a developer command prompt on your machine. Alternatively, open [Cloud Shell](https://cloud.google.com/shell/docs/using-cloud-shell).
+1. Build a Docker image, using the binaries published to the output folder:
+
+    `docker build -t cloudrun-net .`
+
+## Run the container locally
+1. Run the container:
+
+    `docker run --rm -it -p 8080:8080 cloudrun-net`
+
+1. Point your web browser to http://localhost:8080/ and verify that the application is
+   working properly.
+
+## Push the container image to Artifact Registry
+
+1. If you haven't done so already, [create an Artifact Registry Docker repository](https://cloud.google.com/artifact-registry/docs/docker/store-docker-container-images#create).
+1. Retrieve the URI of your Artifact Registry Docker repository:
+    <pre>gcloud artifacts repositories describe <b>REPO-NAME</b> \
+        --location=<b>LOCATION</b> \
+        --format="value(registryUri)"</pre>
+    Replace:
+    - `REPO-NAME` with the name of your Docker repository
+    - `LOCATION` with the location (region / multi-region) where the Docker repository was created
+
+1. Create a environment variable to hold the Docker image's URI
+    <pre>export IMAGE_URI=<b>REGISTRY-URI</b>/cloudrun-net</pre>
+    Replace `REGISTRY-URI` with the URI you retrieved in the previous step.
+1. Tag the image:
+    ```bash
+    docker tag cloudrun-net $IMAGE_URI
+    ```
+1. Push the image to Artifact Registry:
+    ```bash
+    docker push $IMAGE_URI
+    ```
+
+## Deploy to Cloud Run
+1. Deploy the container image to Cloud Run
+    <pre>gcloud run deploy cloudrun-net \
+        --region=<b>REGION</b> \
+        --image=$IMAGE_URI \
+        --allow-unauthenticated</pre>
+    Replace `REGION` with the region you want to deploy the Cloud Run service to.
+
+    If you are prompted to enable additional APIs on the project, for example, the Cloud Run API, respond by pressing y.
+
+1. Point your web browser to the Service URL returned by the command and verify that the   application is working properly.
