Deploy a C# ASP.NET web app to a VM in Azure Stack Hub

You can create a virtual machine (VM) to host your C# ASP.NET web app in Azure Stack Hub. This article shows you how to set up your server, configure it to host your C# ASP.NET web app, and then deploy the app right from Visual Studio.

This article is about using Azure Stack Hub. You can run Azure in your data center using Azure Stack Hub. If you are looking for guidance for global Azure, check out Publish an ASP.NET Core app to Azure with Visual Studio.



Create a VM

Create a VM and then install the components you need to host your .NET web app. You'll need the IIS Management Console, Web management service, .NET runtime, and Microsoft Web Deploy on your VM. You'll need to open the ports for your web server and for Web Deploy from your development machine. When installing the .NET runtime, make sure you're using the same version of .NET on both your target server and development machine.

  1. Create a Windows Server VM.

  2. To install the IIS (with Management Console) and .NET 5.0 components on your VM, run the following script in your PowerShell 5.x console:

    # Install IIS (with Management Console)
    Install-WindowsFeature -name Web-Server -IncludeManagementTools
    # Install Web Management Service
    Install-WindowsFeature -Name Web-Mgmt-Service
  3. Download .NET 5.0 on your VM.

  4. Download Web Deploy v3.6. Install it from the MSI file, and then enable all of the features.

  5. In the Azure Stack Hub portal, open the ports that are listed in the network settings for your VM.

    a. Open the Azure Stack Hub portal for your tenant.

    b. Search for your VM. You might have pinned the VM to your dashboard, or you can search for it in the Search resources box.

    c. Select Networking.

    d. Select Add inbound port rule under VM.

    e. Add an inbound security rule for the following ports:

    Port Protocol Description
    80 HTTP Hypertext Transfer Protocol (HTTP) is the protocol used to deliver web pages from servers. Clients connect via HTTP with a DNS name or IP address.
    443 HTTPS Hypertext Transfer Protocol Secure (HTTPS) is a secure version of HTTP that requires a security certificate and allows for the encrypted transmission of information.
    22 SSH Secure Shell (SSH) is an encrypted network protocol for secure communications. You'll use this connection with an SSH client to configure the VM and deploy the app.
    3389 RDP Optional. The Remote Desktop Protocol allows for a remote desktop connection to use a graphic user interface your machine.
    8172 Custom The port used by Web Deploy.

    For each port:

    a. For Source, select Any.

    b. For Source port range, type an asterisk (*).

    c. For Destination, select Any.

    d. For Destination port range, add the port you want to open.

    e. For Protocol, select Any.

    f. For Action, select Allow.

    g. For Priority, leave the default selection.

    h. Enter a Name and Description to help you remember why the port is open.

    i. Select Add.

  6. In the Overview settings for your VM in Azure Stack Hub, create a DNS name for your server. Users can connect to your website by using the URL.

    a. Open the Azure Stack Hub portal for your tenant.

    b. Search for your VM. You might have pinned the VM to your dashboard, or you can search for it in the Search resources box.

    c. Select Overview.

    d. Under DNS, select Configure.

    e. For Assignment, select Dynamic.

    f. Enter the DNS name label, such as mywebapp, so that your full URL becomes something like

Create an app

You can use either use the default .NET App in Visual Studio, your own web app, an example at Publish an ASP.NET Core app to Azure with Visual Studio. The article describes how to create and publish an ASP.NET web app to an Azure virtual machine by using the Azure Virtual Machines publishing feature in Visual Studio 2019. After you've installed and made sure that your app is running locally, you'll update your publishing target to the Windows VM in your Azure Stack Hub instance.

Deploy and run the app

Create a publish target from your development machine to your VM in Azure Stack Hub.

  1. In Solution Explorer, right-click your project, and then select Publish.

    Deploy an ASP.NET web app to Azure Stack Hub publish

  2. In the Publish window, select New.

  3. Select Web Server (IIS).

  4. Select Next > Web Deploy > Next.

  5. For Server enter the DNS name that you defined earlier, such as

  6. For Site name, enter Default Web Site, or the name used in IIS on your target server.

  7. For User name, enter the user name for the machine.

  8. For Password, enter the password for the machine.

  9. For Destination URL, enter the URL for the site, such as

    Deploy an ASP.NET web app - configure Web Deploy

  10. To validate your web-deploy configuration, select Validate connection, and then select Next.

  11. Set Configuration as Release.

  12. Set Target Framework as net5.0.

  13. Set Deployment Mode as Framework-Dependent.

  14. Set Target Runtime as win-x64.

  15. Select Save.

  16. Select Publish. You should see the following output in your console in Visual Studio:

    Publish Succeeded.
    Web App was published successfully
    ========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========
    ========== Publish: 1 succeeded, 0 failed, 0 skipped ==========
  17. Go to your new server. You should see your running web application.
