Publish an ASP.NET Core app to Azure with Visual Studio Code

With this tutorial, you'll learn how to create an ASP.Net Core MVC Application and deploy it within Visual Studio Code. The tutorial assumes familiarity with VS Code. For more information, see Getting started with VS Code. This tutorial will work on Windows, macOS, or Linux environments. Be sure to use the correct path separating characters (\ vs /) for your environment.

[!INCLUDE Azure App Service Preview Notice]

To troubleshoot an App Service deployment issue, see xref:test/troubleshoot-azure-iis.

Prerequisites

An Azure subscription. Get a free Azure account if you don't have one.
.NET SDK (latest stable release).
Visual Studio Code.
- C# Extension.
- Azure App Service Extension. Use the extension to sign into Azure before proceeding.

Create an ASP.Net Core MVC project

Open the integrated terminal.
Set your working directory (cd) to the directory that will contain the project.
Run the following commands:
```
dotnet new mvc -o MyMVCapp
code -r MyMVCapp
```
For the preceding commands:
- dotnet new mvc -o MyMVCapp
  - Creates a new ASP.NET Core MVC project in the MyMVCapp folder.
- code -r MyMVCapp
  - Loads the MyMVCapp.csproj project file in Visual Studio Code.
  - Visual Studio Code updates the integrated terminal to the project directory.

[!NOTE] If a dialog box appears with Required assets to build and debug are missing from 'MyMVCapp'. Add them?, select Yes.

A new ASP.NET Core MVC project is created in a MyMVCapp folder with a structure similar to the following:

      appsettings.Development.json
      appsettings.json
<DIR> bin
<DIR> Controllers
<DIR> Models
      MyMVCapp.csproj
<DIR> obj
      Program.cs
<DIR> Properties
<DIR> Views
<DIR> wwwroot

A .vscode folder will be created under the project structure. It will contain utility files to help you build and debug your ASP.NET Core web app.

Test the project

Before deploying the app to Azure, make sure it is running properly on your local machine.

Open the integrated terminal (if needed).
Set up the a trusted HTTPS development certificate:

[!INCLUDE]

Run the following command:

dotnet run

The preceding command:

Starts Kestrel, ASP.NET Core's built-in web server.
Displays a URL to test the web app such as http://localhost:<port>, where <port> is the random port number set in Properties\launchSettings.json at project creation.

The output shows messages similar to the following, indicating that the app is running and awaiting requests:

$ dotnet run
Building...
info: Microsoft.Hosting.Lifetime[14]
    Now listening on: https://localhost:7064
info: Microsoft.Hosting.Lifetime[14]
    Now listening on: http://localhost:5119
info: Microsoft.Hosting.Lifetime[0]
    Application started. Press Ctrl+C to shut down.
info: Microsoft.Hosting.Lifetime[0]
    Hosting environment: Development
info: Microsoft.Hosting.Lifetime[0]
    Content root path: D:\Src\MyMVCapp\

Ctrl+click the HTTPS URL in the output to test the web app in a browser. In the example above, the URL is https://localhost:7064.
Press Ctrl+C in the integrated terminal to shut down the web app after testing it.

Generate the deployment package locally

In the integrated terminal, use the following command to generate a Release package in a folder located at bin/Publish:
```
dotnet publish -c Release -o ./bin/Publish
```
A new Publish subfolder will be created in the bin folder. This folder contains the files to be deployed to Azure.

Publish to Azure App Service

Leveraging the Azure App Service extension for Visual Studio Code, follow the steps below to publish the website directly to the Azure App Service.

Create a new Azure Web App resource

If you don't have an existing Azure Web App resource to publish to, you must create one.

In the Azure extension tab, in the RESOURCES pane, expand the subscription you wish to use.
Right-click App Services and select Create New Web App....
Follow the prompts:
1. Enter a unique name for the web app.
2. Select the most recent stable .NET runtime (such as .NET 6 (LTS)). Do not select the ASP.NET runtime, which is for .NET Framework apps.
3. Select your pricing tier. Free (F1) is acceptable for this tutorial.

Publish to Azure

Right click the bin\Publish folder and select Deploy to Web App... and follow the prompts.
1. Select the subscription where the Azure Web App resource is located.
2. Select the Azure Web App resource to which you will publish.
3. Select Deploy when prompted with a confirmation dialog.
Once the deployment is finished, click Browse Website to validate the deployment.

Once you click Browse Website, you'll navigate to it using your default browser:

[!TIP] You can repeat the above steps to redeploy the app to the same Azure Web App resource as needed. Be sure to run dotnet publish again before you deploy to Azure.
