Aspire.Hosting.Azure.Network library

Provides extension methods and resource definitions for an Aspire AppHost to configure Azure Virtual Networks, Subnets, NAT Gateways, Public IP Addresses, Network Security Groups, and Private Endpoints.

Getting started

Prerequisites

Install the package

Install the Aspire Azure Virtual Network Hosting library with NuGet:

dotnet add package Aspire.Hosting.Azure.Network

Configure Azure Provisioning for local development

Adding Azure resources to the Aspire application model will automatically enable development-time provisioning for Azure resources so that you don't need to configure them manually. Provisioning requires a number of settings to be available via .NET configuration. Set these values in user secrets in order to allow resources to be configured automatically.

{
    "Azure": {
      "SubscriptionId": "<your subscription id>",
      "ResourceGroupPrefix": "<prefix for the resource group>",
      "Location": "<azure location>"
    }
}

NOTE: Developers must have Owner access to the target subscription so that role assignments can be configured for the provisioned resources.

Usage examples

Adding a Virtual Network

In the AppHost.cs file of AppHost, add a Virtual Network using the following method:

var vnet = builder.AddAzureVirtualNetwork("vnet");

By default, the virtual network will use the address prefix 10.0.0.0/16. You can specify a custom address prefix:

var vnet = builder.AddAzureVirtualNetwork("vnet", "10.1.0.0/16");

Adding Subnets

You can add subnets to your virtual network:

var vnet = builder.AddAzureVirtualNetwork("vnet");
var subnet = vnet.AddSubnet("subnet", "10.0.1.0/24");

Adding NAT Gateways

A NAT Gateway provides outbound internet connectivity with deterministic public IP addresses:

var natGateway = builder.AddNatGateway("nat");

var vnet = builder.AddAzureVirtualNetwork("vnet");
var subnet = vnet.AddSubnet("aca-subnet", "10.0.0.0/23")
    .WithNatGateway(natGateway);

By default, a Public IP Address is automatically created. You can provide an explicit one for full control:

var pip = builder.AddPublicIPAddress("nat-pip");
var natGateway = builder.AddNatGateway("nat")
    .WithPublicIPAddress(pip);

Use ConfigureInfrastructure for advanced settings like idle timeout or availability zones.

Adding Network Security Groups

Add security rules to control traffic flow on subnets using shorthand methods:

var vnet = builder.AddAzureVirtualNetwork("vnet");
var subnet = vnet.AddSubnet("web", "10.0.1.0/24")
    .AllowInbound(port: "443", from: AzureServiceTags.AzureLoadBalancer, protocol: SecurityRuleProtocol.Tcp)
    .DenyInbound(from: AzureServiceTags.Internet);

An NSG is automatically created when shorthand methods are used. Priority auto-increments (100, 200, 300...) and rule names are auto-generated.

For full control, create an explicit NSG with AzureSecurityRule objects:

var nsg = vnet.AddNetworkSecurityGroup("web-nsg")
    .WithSecurityRule(new AzureSecurityRule
    {
        Name = "allow-https",
        Priority = 100,
        Direction = SecurityRuleDirection.Inbound,
        Access = SecurityRuleAccess.Allow,
        Protocol = SecurityRuleProtocol.Tcp,
        DestinationPortRange = "443"
    });

var subnet = vnet.AddSubnet("web-subnet", "10.0.1.0/24")
    .WithNetworkSecurityGroup(nsg);

A single NSG can be shared across multiple subnets.

Adding Private Endpoints

Create a private endpoint to securely connect to Azure resources over a private network:

var vnet = builder.AddAzureVirtualNetwork("vnet");
var peSubnet = vnet.AddSubnet("private-endpoints", "10.0.2.0/24");

var storage = builder.AddAzureStorage("storage");
var blobs = storage.AddBlobs("blobs");

// Add a private endpoint for the blob storage
peSubnet.AddPrivateEndpoint(blobs);

When you add a private endpoint to an Azure resource:

  1. A Private DNS Zone is automatically created for the service (e.g., privatelink.blob.core.windows.net)
  2. A Virtual Network Link connects the DNS zone to your VNet
  3. A DNS Zone Group is created on the private endpoint for automatic DNS registration
  4. The target resource is automatically configured to deny public network access

To override the automatic network lockdown, use ConfigureInfrastructure:

storage.ConfigureInfrastructure(infra =>
{
    var storageAccount = infra.GetProvisionableResources()
        .OfType<StorageAccount>()
        .Single();
    storageAccount.PublicNetworkAccess = StoragePublicNetworkAccess.Enabled;
});
