02 - First Deploy (Consumption)

Deploy your .NET 8 isolated worker app to the Consumption plan with long-form Azure CLI commands and validate your first production endpoint.

Prerequisites

Tool Version Purpose
.NET SDK 8.0 (LTS) Build and run isolated worker functions
Azure Functions Core Tools v4 Start local host and publish artifacts
Azure CLI 2.61+ Provision Azure resources and inspect app state

Consumption plan basics

Consumption (Y1) scales to zero and charges per execution. Default timeout is 5 minutes (max 10 minutes). No VNet integration on this plan.

What You'll Build

A Linux Consumption Function App running the .NET 8 isolated worker, deployed from your local project with Core Tools, then validated through all HTTP endpoints.

Steps

Step 1 - Set deployment variables

export RG="rg-func-dotnet-con-demo"
export LOCATION="koreacentral"
export STORAGE_NAME="stdotnetcon0410"
export APP_NAME="func-dotnetcon-04100220"

Step 2 - Create resource group and storage account

az group create \
  --name "$RG" \
  --location "$LOCATION"

az storage account create \
  --name "$STORAGE_NAME" \
  --resource-group "$RG" \
  --location "$LOCATION" \
  --sku Standard_LRS

Step 3 - Create the Consumption function app

az functionapp create \
  --name "$APP_NAME" \
  --resource-group "$RG" \
  --storage-account "$STORAGE_NAME" \
  --consumption-plan-location "$LOCATION" \
  --runtime dotnet-isolated \
  --runtime-version 8 \
  --functions-version 4 \
  --os-type Linux

Step 4 - Create trigger resources

az storage queue create \
  --name "incoming-orders" \
  --account-name "$STORAGE_NAME"

az storage container create \
  --name "uploads" \
  --account-name "$STORAGE_NAME"

Step 5 - Configure app settings

STORAGE_CONN=$(az storage account show-connection-string \
  --name "$STORAGE_NAME" \
  --resource-group "$RG" \
  --query connectionString \
  --output tsv)

az functionapp config appsettings set \
  --name "$APP_NAME" \
  --resource-group "$RG" \
  --settings \
    "QueueStorage=$STORAGE_CONN" \
    "EventHubConnection=Endpoint=sb://placeholder.servicebus.windows.net/;SharedAccessKeyName=placeholder;SharedAccessKey=cGxhY2Vob2xkZXI=;EntityPath=events"

Step 6 - Build and publish

cd apps/dotnet
dotnet publish --configuration Release --output ./publish

cd publish
func azure functionapp publish "$APP_NAME" --dotnet-isolated

Must pass --dotnet-isolated flag

When publishing from the compiled output directory, Core Tools cannot detect the project language. Always pass --dotnet-isolated to specify the worker runtime explicitly.

Step 7 - Verify function list

az functionapp function list \
  --name "$APP_NAME" \
  --resource-group "$RG" \
  --query "[].{name:name, language:language}" \
  --output table

Expected output (16 functions):

Name                                          Language

func-dotnetcon-04100220/timerLab              dotnet-isolated
func-dotnetcon-04100220/unhandledError        dotnet-isolated

Step 8 - Test HTTP endpoints

curl --request GET "https://$APP_NAME.azurewebsites.net/api/health"
curl --request GET "https://$APP_NAME.azurewebsites.net/api/hello/Consumption"
curl --request GET "https://$APP_NAME.azurewebsites.net/api/info"

Verification

Uploading 6.82 MB [-----------------------------------------------------------]
Upload completed successfully.
Deployment completed successfully.

App state:

-------  -----------------------------------------  -----------------
Running  func-dotnetcon-04100220.azurewebsites.net  functionapp,linux

Health endpoint response:

{"status":"healthy","timestamp":"2026-04-09T17:46:52.625Z","version":"1.0.0"}

.NET upload size

The .NET isolated worker publish output is approximately 6.82 MB, larger than Java (~326 KB) because it includes the ASP.NET Core runtime dependencies.
