02 - First Deploy (Dedicated)

Deploy your .NET 8 isolated worker app to a Dedicated (App Service Plan) B1 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

Dedicated plan basics

Dedicated (App Service Plan) runs on pre-provisioned compute with predictable cost. Always On keeps the host loaded for non-HTTP triggers. Supports VNet integration and deployment slots on eligible SKUs. No execution timeout limit.

What You'll Build

A Linux Dedicated Function App running the .NET 8 isolated worker on a B1 App Service Plan, 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-ded-demo"
export LOCATION="koreacentral"
export STORAGE_NAME="stdnetded0410"
export PLAN_NAME="plan-dnetded-04100301"
export APP_NAME="func-dnetded-04100301"

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 Dedicated App Service Plan

az appservice plan create \
  --name "$PLAN_NAME" \
  --resource-group "$RG" \
  --location "$LOCATION" \
  --sku B1 \
  --is-linux

Dedicated plan uses az appservice plan create

Unlike Premium which uses az functionapp plan create, Dedicated plans use az appservice plan create. This creates a standard App Service Plan that can host both Function Apps and Web Apps.

Step 4 - Create the function app on the Dedicated plan

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

Step 5 - 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 6 - 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 7 - 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 8 - 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-dnetded-04100301/blobProcessor           dotnet-isolated
func-dnetded-04100301/dnsResolve              dotnet-isolated

func-dnetded-04100301/queueProcessor          dotnet-isolated
func-dnetded-04100301/scheduledCleanup        dotnet-isolated
func-dnetded-04100301/slowResponse            dotnet-isolated
func-dnetded-04100301/storageProbe            dotnet-isolated
func-dnetded-04100301/testError               dotnet-isolated
func-dnetded-04100301/timerLab                dotnet-isolated
func-dnetded-04100301/unhandledError          dotnet-isolated

Fast indexing on Dedicated

Unlike Premium and Consumption plans, Dedicated plans typically index all functions immediately after publish. You should see all 16 functions in the list without any delay.

Step 9 - Test HTTP endpoints

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

.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.
