How to Deploy .NET to Azure App Service Easily

To deploy a .NET app to Azure App Service, first publish your app using dotnet publish to create deployable files. Then, use az webapp deploy or Azure Portal to upload and run your app on the cloud service.

Syntax

Deploying a .NET app to Azure App Service involves two main commands:

• dotnet publish -c Release -o <output-folder>: Builds and prepares your app files for deployment.
• az webapp deploy --resource-group <rg> --name <app-name> --src-path <output-folder>: Uploads your published app to Azure App Service.

Replace placeholders with your actual resource group, app name, and output folder path.

bash

dotnet publish -c Release -o ./publish
az webapp deploy --resource-group MyResourceGroup --name MyDotnetApp --src-path ./publish

Example

This example shows how to publish a .NET app and deploy it to Azure App Service using Azure CLI.

bash

dotnet publish -c Release -o ./publish
az webapp deploy --resource-group MyResourceGroup --name MyDotnetApp --src-path ./publish

Output

Uploading files to Azure App Service...
Deployment successful.

Common Pitfalls

Common mistakes when deploying .NET apps to Azure App Service include:

• Not publishing the app before deployment, causing missing files.
• Using wrong resource group or app service name in commands.
• Forgetting to configure the app service runtime stack to match your .NET version.
• Deploying to a stopped or misconfigured App Service.

Always verify your Azure App Service is running and configured for the correct .NET version before deploying.

bash

Wrong:
az webapp deploy --resource-group WrongGroup --name WrongApp --src-path ./publish

Right:
az webapp deploy --resource-group MyResourceGroup --name MyDotnetApp --src-path ./publish

Quick Reference

Remember these quick tips for smooth deployment:

• Use dotnet publish to prepare your app files.
• Deploy with az webapp deploy or Azure Portal drag-and-drop.
• Match App Service runtime stack with your .NET version.
• Check App Service status before deploying.

Key Takeaways

Always publish your .NET app before deploying to Azure App Service.

Use Azure CLI's az webapp deploy command for easy deployment.

Ensure your App Service runtime matches your .NET app version.

Verify resource group and app service names are correct in commands.

Check that your App Service is running before deploying.
