You can use Visual Studio or the command line to set up your project. The tools guide you through each step. You can test your app locally before you publish it to the cloud.

CI Systems Overview

Continuous Integration (CI) systems help you automate the process of building and testing your app. You can use popular CI tools like GitHub Actions, Azure Pipelines, or GitLab CI. These tools watch your code for changes. When you update your code, the CI system builds your app and runs tests.

You can set up a workflow to Publish Your App automatically. The CI system can build your .NET Aspire project, run checks, and deploy it to your chosen cloud or server. This process saves you time and reduces errors.

Here is a simple example of a CI workflow using YAML:

steps:
  - uses: actions/checkout@v3
  - name: Setup .NET
    uses: actions/setup-dotnet@v3
    with:
      dotnet-version: '8.0.x'
  - name: Build
    run: dotnet build
  - name: Test
    run: dotnet test
  - name: Publish
    run: dotnet publish --output ./publish

Note: You can customize your workflow to fit your needs. Add steps for security checks or deployment as needed.

Setup

Prerequisites

Before you start, you need to gather a few tools and accounts. These help you build, test, and deploy your app with .NET Aspire and CI workflows.

• Install the latest version of the .NET SDK (8.0 or higher).

• Set up Visual Studio 2022 or later, or use Visual Studio Code with the C# extension.

• Create an account on a code hosting platform like GitHub, Azure DevOps, or GitLab.

• Install Docker Desktop if you want to use containers.

• Make sure you have access to a cloud provider, such as Azure, AWS, or Google Cloud.

Tip: You do not need to pick a cloud provider right away. .NET Aspire works with many clouds, so you can switch later if you want.

Environment Preparation

You can prepare your environment in a few simple steps. First, open your terminal or Visual Studio. If you have an existing app, you can add .NET Aspire by running:

dotnet add package Aspire.Hosting

This command adds the Aspire tools to your project. You can now organize your app into services. Each service can run on its own, which helps you scale and manage your app.

Next, set up your CI workflow. Most platforms let you create a YAML file to define your build and deploy steps. You can use the sample from earlier or customize it for your needs.

You can test your app locally before you Publish Your App. Use Docker to run your services together. When you are ready, deploy to your chosen cloud. .NET Aspire keeps your setup cloud-agnostic, so you can move your app easily.

Publish Your App

Configuration

You need to set up your app before you can publish it. Start by checking your project files. Make sure you have all the services and dependencies listed in your configuration files. You can use appsettings.json to store settings like connection strings and API keys. This file helps you keep your secrets safe and your app organized.

If you use containers, create a Dockerfile for each service. This file tells Docker how to build and run your app. You can also use a docker-compose.yml file to run many services together. This setup lets you test your app locally before you move to the cloud.

Tip: Use environment variables for secrets. This keeps your sensitive data out of your code.

You can use Visual Studio to manage your configuration. Open your project, right-click on it, and choose "Manage User Secrets" to store sensitive information. Visual Studio helps you keep your settings in one place.

CI Integration

You can connect your app to a CI system to automate your workflow. CI tools like GitHub Actions, Azure Pipelines, or GitLab CI watch your code for changes. When you push new code, the CI system builds, tests, and prepares your app for deployment.

Follow these steps to set up CI integration:

1. Create a YAML file in your repository. Name it .github/workflows/ci.yml for GitHub Actions.

2. Add steps to check out your code, set up .NET, build, test, and publish your app.

3. Use the dotnet publish command to create files ready for deployment.

Here is a sample GitHub Actions workflow:

name: Publish Your App CI

on:
  push:
    branches: [ main ]

jobs:
  build-and-publish:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Setup .NET
        uses: actions/setup-dotnet@v3
        with:
          dotnet-version: '8.0.x'
      - name: Build
        run: dotnet build
      - name: Test
        run: dotnet test
      - name: Publish
        run: dotnet publish --output ./publish

Note: You can add more steps for security checks or notifications.

Deployment Steps

You can deploy your app in different ways. Visual Studio gives you a simple way to deploy. Click "Publish" in the toolbar, choose your target (like Azure or a local folder), and follow the prompts. Visual Studio handles the details for you.

If you use Azure, you can deploy your app as a web app or a container. Use the Azure Portal or the Azure CLI. For containers, push your images to Azure Container Registry, then deploy them to Azure App Service or Azure Kubernetes Service.

You can also use Docker for local orchestration. Run docker-compose up to start all your services together. This helps you test your app before you move to production.

Here is a quick checklist for deployment:

• Build your app and its services.

• Test everything locally with Docker or Visual Studio.

• Use your CI system to automate the build and publish steps.

• Deploy to your chosen cloud or server.

Callout: You can move your app between clouds without changing much. .NET Aspire keeps your setup flexible and cloud-agnostic.

You can now Publish Your App with confidence. The steps above help you move from code to cloud quickly. You can use Visual Studio, Azure, or containers to fit your needs. Local orchestration lets you test everything before you go live. Production deployment works the same way, just on a bigger scale.

Monitoring and Optimization

Telemetry

You need to check your app’s health and speed. Telemetry lets you see what is happening inside your app. You can use .NET Aspire tools to collect logs, metrics, and traces. These tools show how your app works and where it spends time. You can find slow spots or errors fast.

You can send telemetry data to cloud services like Azure Monitor or Application Insights. These services give you dashboards and alerts. You can set alerts for errors or slow responses. This helps you fix problems before users notice.

Tip: Always turn on logging in your services. Logs help you know what happened if something goes wrong.
