You've built a web app, tested it locally, and now you need to get it live. The old approach meant switching between your IDE and the Azure portal, filling in forms, copying keys, and hoping nothing broke. There is a simpler way. If you already use Visual Studio 2022, you can create and publish an Azure App Service without ever opening a browser. This walkthrough covers every step.
What You Need Before Starting
Confirm your setup matches these three requirements. You need an Azure subscription (free or paid). You need Visual Studio 2022 installed with the ASP.NET and web development workload enabled. Your ASP.NET Core web application must be running cleanly on your local machine before you attempt deployment. If your environment needs configuration help, Microsoft's official documentation covers the full setup process for Windows-based Azure development tools.
Step-by-Step: Publishing from Inside Visual Studio
Open your solution in Visual Studio and locate your project in Solution Explorer. Right-click the project name and select "Publish…" to open the publish dialog. You will see several destination options—select Azure and click Next.
Choose "Specific target" from the left sidebar. From the list of Azure services, pick "Azure App Service (Windows)" and click Next again. Sign in to your Azure account when prompted to link Visual Studio directly to your subscription.
From here you have two paths: deploy to an existing App Service instance, or create a new one on the spot. For a new deployment, click the green plus icon next to the App Service field. A dialog appears that mirrors the options you would find in the Azure portal, so the learning curve is minimal.
Name your service—this becomes the first part of your public URL, so it must be globally unique. Azure accepts letters, numbers, and dashes. Select your subscription, then choose or create a resource group to organize your resources. Finally, pick or create a hosting plan that matches your performance and budget needs.
Click Create once all fields are populated. Azure provisions your App Service and hosting plan in the background. Back in the publish dialog, your new instance appears selected. Click Publish. Visual Studio compiles your application, packages the files, and uploads them to Azure. When deployment finishes, your browser opens automatically to your live site.
Our Analysis: Why This Matters
Azure App Service deployment workflows sit at the intersection of infrastructure configuration and developer productivity. The approach described here removes friction by keeping the entire process inside Visual Studio.
The main advantage is continuity. Context switching between an IDE and a browser introduces opportunities for error—expired sessions, copy-paste mistakes, misread form fields. Keeping everything in one window reduces steps and surface area for problems. When you need to update your app later, the saved publish profile lets you redeploy with a single click, bypassing the wizard entirely.
The tradeoff is environment lock-in. Visual Studio is a Windows desktop application. Developers working on macOS or Linux would need the Azure CLI or other tools to replicate this workflow. For teams already invested in the Microsoft ecosystem, though, this streamlined path represents a genuine time savings.
What to watch: Azure updates its tooling regularly, so dialog labels and available options may shift slightly between versions. The core workflow—right-click, select Azure target, publish—remains consistent.
Who Should Care
| Scenario | Recommended Approach |
|---|---|
| Primary development in Visual Studio on Windows | Use the built-in publish workflow described here |
| Need granular hosting configuration (staging slots, custom scaling) | Use the Azure portal directly |
| Development on macOS or Linux | Use Azure CLI, VS Code extensions, or CI/CD pipelines |
| Quick prototypes or MVPs | Visual Studio publish wizard |
| Enterprise apps requiring audit trails | Azure portal or Infrastructure-as-Code tools |
Key takeaways
- Visual Studio 2022 can create and deploy Azure App Services without touching the Azure portal
- The process requires an Azure subscription, Visual Studio with the web workload, and a working local ASP.NET Core project
- The deployed app URL follows the pattern yourname.azurewebsites.net
- Saved publish profiles let you redeploy quickly after code changes
- This workflow suits any developer building cloud-connected services in a Windows environment
Frequently asked questions
Do I need a paid Azure subscription to follow this guide?
No. A free Azure subscription works fine for this process. You can experiment within free tier limits before committing to a paid plan.
Can I use this method to deploy apps built with frameworks other than ASP.NET Core?
Visual Studio's publish wizard supports multiple target frameworks, but the specific dialogs and options shown here apply to ASP.NET Core web applications.
What happens if my app name is already taken?
Azure requires globally unique App Service names. If your chosen name is in use, you will see an error and must pick a different one before proceeding.
Is it possible to update a deployed app without recreating the App Service?
Yes. The publish profile Visual Studio saves after your first deployment can be reused. Clicking Publish again updates the existing service with your new code.
Can I connect a custom domain to an App Service created this way?
Yes, but that step happens in the Azure portal after deployment. Custom domain mapping is separate from the Visual Studio publish workflow.
