Entra ID Provisioning for .NET Aspire

Provision Entra ID app registrations for Aspire solutions and update appsettings.json configuration.

Prerequisites

Install Microsoft Graph PowerShell

# Install the required modules (only if needed, one-time setup)
Install-Module Microsoft.Graph.Applications -Scope CurrentUser -Force
Install-Module Microsoft.Graph.Identity.SignIns -Scope CurrentUser -Force

# Note: Microsoft.Graph.Users is NOT required - this skill uses Invoke-MgGraphRequest
# to get current user info, which avoids module version compatibility issues.

Connect to Microsoft Graph

# Connect with required scopes
Connect-MgGraph -Scopes "Application.ReadWrite.All", "Directory.ReadWrite.All"

# Verify connection
Get-MgContext

Note: You may be prompted to consent to permissions on first use.

Provisioning Checklist

Use this checklist to verify all provisioning steps are complete:

For Each Web API Project

  • App registration created (or existing one found or user-provided)
  • App ID URI set (api://{clientId})
  • access_as_user scope configured
  • Service principal created
  • Current user added as owner
  • appsettings.json updated with TenantId and ClientId

For Each Web App Project

  • App registration created (or existing one found or user-provided)
  • Redirect URIs configured (from launchSettings.json)
  • Client secret generated and stored in user-secrets
  • API permission added (to call the web API)
  • Admin consent granted (or manual steps provided)
  • Service principal created
  • Current user added as owner
  • appsettings.json updated with TenantId, ClientId, and Scopes

Final Verification

  • API provisioned before web app (web app needs API's ClientId and ScopeId)
  • All appsettings.json files have real GUIDs (no placeholders)
  • Client secret stored in user-secrets (not in appsettings.json)
  • Disconnect-MgGraph called when done

When to Use This Skill

Use this skill after the entra-id-aspire-authentication skill has added authentication code. This skill:

  • Creates or updates Entra ID app registrations
  • Configures App ID URIs and scopes for APIs
  • Sets up redirect URIs for web apps
  • Generates client secrets and stores them securely
  • Updates appsettings.json with TenantId, ClientId, and scopes

Workflow

Step 1: Detect Project Types

Scan Program.cs files to identify which projects need app registrations:

# Detect projects with Microsoft.Identity.Web
Get-ChildItem -Recurse -Filter "Program.cs" | ForEach-Object {
    $content = Get-Content $_.FullName -Raw
    $projectDir = Split-Path $_.FullName -Parent
    $projectName = Split-Path $projectDir -Leaf
    
    if ($content -match "AddMicrosoftIdentityWebApi") {
        Write-Host "API: $projectName"
    } elseif ($content -match "AddMicrosoftIdentityWebApp") {
        Write-Host "WebApp: $projectName"
    }
}

Step 2: Gather Configuration

Before provisioning, the agent MUST gather required information interactively.

2a. Get Tenant ID

First, detect the default tenant from the current connection if Microsoft Graph powershell is connected:

$context = Get-MgContext
if ($context) {
    $defaultTenant = $context.TenantId
    Write-Host "Connected to tenant: $defaultTenant"
} else {
    Write-Host "Not connected. Run: Connect-MgGraph -TenantId '<tenant-id>' -Scopes 'Application.ReadWrite.All'"
}

AGENT: Ask the user:

"I detected tenant ID {defaultTenant}. Should I use this tenant, or would you like to specify a different one?"

  • If user confirms → use $defaultTenant
  • If user provides different ID → use that value
  • If not connected → instruct user to run Connect-MgGraph first

2b. Check for Existing ClientIds in appsettings.json

Before asking about new vs. existing apps, scan appsettings.json files:

# === Detect existing ClientIds from appsettings.json ===

$projects = @()

Get-ChildItem -Recurse -Filter "Program.cs" | ForEach-Object {
    $content = Get-Content $_.FullName -Raw
    $projectDir = Split-Path $_.FullName -Parent
    $projectName = Split-Path $projectDir -Leaf
    
    # Skip AppHost and ServiceDefaults
    if ($projectName -match "AppHost|ServiceDefaults") { return }
    
    $appSettingsPath = Join-Path $projectDir "appsettings.json"
    $existingClientId = $null
    $isPlaceholder = $false
    
    if (Test-Path $appSettingsPath) {
        $appSettings = Get-Content $appSettingsPath -Raw | ConvertFrom-Json
        if ($appSettings.AzureAd.ClientId) {
            $clientId = $appSettings.AzureAd.ClientId
            # Check if it's a placeholder value
            if ($clientId -match "^<.*>$" -or $clientId -match "YOUR_" -or $clientId -eq "") {
                $isPlaceholder = $true
            } else {
                $existingClientId = $clientId
            }
        }
    }
    
    $projectType = $null
    if ($content -match "AddMicrosoftIdentityWebApi") {
        $projectType = "API"
    } elseif ($content -match "AddMicrosoftIdentityWebApp") {
        $projectType = "WebApp"
    }
    
    if ($projectType) {
        $projects += @{
            Name = $projectName
            Path = $projectDir
            Type = $projectType
            ExistingClientId = $existingClientId
            IsPlaceholder = $isPlaceholder
        }
    }
}

# Output findings
$projects | ForEach-Object {
    if ($_.ExistingClientId) {
        Write-Host "$($_.Type): $($_.Name) - EXISTING ClientId: $($_.ExistingClientId)" -ForegroundColor Yellow
    } elseif ($_.IsPlaceholder) {
        Write-Host "$($_.Type): $($_.Name) - Placeholder ClientId (needs provisioning)" -ForegroundColor Cyan
    } else {
        Write-Host "$($_.Type): $($_.Name) - No ClientId configured" -ForegroundColor Cyan
    }
}

AGENT: Based on findings, ask the user:

If existing ClientIds found:

"I found existing app registrations in your configuration:

  • API ({apiProjectName}): ClientId {apiClientId}
  • Web App ({webProjectName}): ClientId {webClientId}

Should I:

  1. Use these existing apps and complement them if needed (add missing scopes, redirect URIs)?
  2. Create new app registrations and update the configuration?"

If only placeholders or no ClientIds:

"No existing app registrations found in appsettings.json. I'll create new ones."

  • If user chooses existing → use the "Existing App Flow" section with detected ClientIds
  • If user chooses new → proceed to Step 3

2c. Confirm or Provide ClientIds

Based on the detection results, present options to the user:

AGENT: Ask the user:

"I found the following configuration:

  • API ({apiProjectName}): {ClientId: {id} OR No ClientId configured}
  • Web App ({webProjectName}): {ClientId: {id} OR No ClientId configured}

What would you like to do?

  1. Create new app registrations for projects without valid ClientIds
  2. Use existing app registrations — provide ClientIds if not detected
  3. Replace all — create new apps even if ClientIds exist"

If user provides ClientIds manually:

"Please provide the ClientIds:

  • API ClientId: ___
  • Web App ClientId: ___"

Store the final decision:

# Final configuration after user input
$apiConfig = @{
    ProjectName = "MyService.ApiService"
    ProjectPath = "path/to/api"
    ClientId = $null  # Or user-provided/detected GUID
    Action = "Create" # Or "UseExisting"
}

$webConfig = @{
    ProjectName = "MyService.Web"
    ProjectPath = "path/to/web"
    ClientId = $null  # Or user-provided/detected GUID
    Action = "Create" # Or "UseExisting"
}

Decision logic:

  • If Action = "Create" → proceed to Step 3 (provision new app)
  • If Action = "UseExisting" → use the "Existing App Flow" section with the ClientId (detected or user-provided)

Important for existing apps:

  • Web APIs: The Existing App Flow checks for and adds access_as_user scope if missing
  • Web Apps: Run Step 5 (Discover Redirect URIs) first, then pass URIs to Existing App Flow to add any missing redirect URIs
  • Both: App ID URI and service principal are created if missing

Step 3: Provision API App Registration

For each project with AddMicrosoftIdentityWebApi:

# === Provision API App Registration ===

param(
    [Parameter(Mandatory=$true)][string]$TenantId,
    [Parameter(Mandatory=$true)][string]$DisplayName,
    [string]$SignInAudience = "AzureADMyOrg"
)

Write-Host "Creating API app registration: $DisplayName" -ForegroundColor Cyan

# Create the app registration
$apiApp = New-MgApplication -DisplayName $DisplayName -SignInAudience $SignInAudience

$apiClientId = $apiApp.AppId
$apiObjectId = $apiApp.Id

Write-Host "Created app: $apiClientId"

# Set App ID URI
$appIdUri = "api://$apiClientId"
Update-MgApplication -ApplicationId $apiObjectId -IdentifierUris @($appIdUri)
Write-Host "Set App ID URI: $appIdUri"

# Expose scope: access_as_user
$scopeId = [guid]::NewGuid().ToString()
$scope = @{
    Id = $scopeId
    AdminConsentDescription = "Allow the application to access $DisplayName on behalf of the signed-in user."
    AdminConsentDisplayName = "Access $DisplayName"
    IsEnabled = $true
    Type = "User"
    UserConsentDescription = "Allow the application to access $DisplayName on your behalf."
    UserConsentDisplayName = "Access $DisplayName"
    Value = "access_as_user"
}

$api = @{
    Oauth2PermissionScopes = @($scope)
}

Update-MgApplication -ApplicationId $apiObjectId -Api $api
Write-Host "Added scope: access_as_user (id: $scopeId)"

# Create service principal
New-MgServicePrincipal -AppId $apiClientId | Out-Null
Write-Host "Created service principal"

# Add current user as owner (using Invoke-MgGraphRequest for robustness - avoids module version issues)
$currentUser = Invoke-MgGraphRequest -Method GET -Uri "https://graph.microsoft.com/v1.0/me"
if ($currentUser) {
    $ownerRef = @{
        "@odata.id" = "https://graph.microsoft.com/v1.0/directoryObjects/$($currentUser.id)"
    }
    New-MgApplicationOwnerByRef -ApplicationId $apiObjectId -BodyParameter $ownerRef
    Write-Host "Added owner: $($currentUser.userPrincipalName)"
}

# Output for next steps
Write-Host ""
Write-Host "=== API Provisioning Complete ===" -ForegroundColor Green
Write-Host "ClientId: $apiClientId"
Write-Host "AppIdUri: $appIdUri"
Write-Host "ScopeId: $scopeId"
Write-Host "Owner: $($currentUser.userPrincipalName)"

Step 4: Update API appsettings.json

Update the API project's appsettings.json:

{
  "AzureAd": {
    "Instance": "https://login.microsoftonline.com/",
    "TenantId": "<tenant-id>",
    "ClientId": "<api-client-id>",
    "Audiences": ["api://<api-client-id>"]
  }
}

Step 5: Discover Redirect URIs

Parse Properties/launchSettings.json for the web project:

# === Discover Redirect URIs ===

param(
    [Parameter(Mandatory=$true)][string]$ProjectPath
)

$launchSettingsPath = Join-Path $ProjectPath "Properties/launchSettings.json"
$launchSettings = Get-Content $launchSettingsPath | ConvertFrom-Json

$redirectUris = @()

foreach ($profile in $launchSettings.profiles.PSObject.Properties) {
    $appUrl = $profile.Value.applicationUrl
    if ($appUrl) {
        $urls = $appUrl -split ";"
        foreach ($url in $urls) {
            if ($url -match "^https://") {
                $redirectUris += "$url/signin-oidc"
            }
        }
    }
}

Write-Host "Redirect URIs: $($redirectUris -join ', ')"
$redirectUris

Step 6: Provision Web App Registration

For each project with AddMicrosoftIdentityWebApp:

# === Provision Web App Registration ===

param(
    [Parameter(Mandatory=$true)][string]$TenantId,
    [Parameter(Mandatory=$true)][string]$DisplayName,
    [Parameter(Mandatory=$true)][string]$ApiClientId,
    [Parameter(Mandatory=$true)][string]$ApiScopeId,
    [Parameter(Mandatory=$true)][string[]]$RedirectUris,
    [string]$SignInAudience = "AzureADMyOrg"
)

Write-Host "Creating Web app registration: $DisplayName" -ForegroundColor Cyan

# Configure web platform with redirect URIs and enable ID tokens
$webConfig = @{
    RedirectUris = $RedirectUris
    ImplicitGrantSettings = @{
        EnableIdTokenIssuance = $true
    }
}

# Create the app registration
$webApp = New-MgApplication `
    -DisplayName $DisplayName `
    -SignInAudience $SignInAudience `
    -Web $webConfig

$webClientId = $webApp.AppId
$webObjectId = $webApp.Id

Write-Host "Created app: $webClientId"

# Add API permission for access_as_user scope
# First, get the Microsoft Graph resource ID for the API
$apiServicePrincipal = Get-MgServicePrincipal -Filter "appId eq '$ApiClientId'"

$requiredResourceAccess = @{
    ResourceAppId = $ApiClientId
    ResourceAccess = @(
        @{
            Id = $ApiScopeId
            Type = "Scope"
        }
    )
}

Update-MgApplication -ApplicationId $webObjectId -RequiredResourceAccess @($requiredResourceAccess)
Write-Host "Added API permission for $ApiClientId"

# Create client secret
$passwordCredential = @{
    DisplayName = "dev-secret"
    EndDateTime = (Get-Date).AddYears(1)
}

$secret = Add-MgApplicationPassword -ApplicationId $webObjectId -PasswordCredential $passwordCredential
$secretValue = $secret.SecretText

Write-Host "Created client secret"

# Create service principal for the web app
New-MgServicePrincipal -AppId $webClientId | Out-Null
Write-Host "Created service principal"

# Add current user as owner (using Invoke-MgGraphRequest for robustness - avoids module version issues)
$currentUser = Invoke-MgGraphRequest -Method GET -Uri "https://graph.microsoft.com/v1.0/me"
if ($currentUser) {
    $ownerRef = @{
        "@odata.id" = "https://graph.microsoft.com/v1.0/directoryObjects/$($currentUser.id)"
    }
    New-MgApplicationOwnerByRef -ApplicationId $webObjectId -BodyParameter $ownerRef
    Write-Host "Added owner: $($currentUser.userPrincipalName)"
}

# Output for next steps
Write-Host ""
Write-Host "=== Web App Provisioning Complete ===" -ForegroundColor Green
Write-Host "ClientId: $webClientId"
Write-Host "Secret: $secretValue"
Write-Host "Owner: $($currentUser.userPrincipalName)"
Write-Host ""
Write-Host "IMPORTANT: Store this secret securely. It will not be shown again."

Step 7: Store Secret in User Secrets

# === Store secret in dotnet user-secrets ===

param(
    [Parameter(Mandatory=$true)][string]$ProjectPath,
    [Parameter(Mandatory=$true)][string]$Secret
)

Push-Location $ProjectPath

# Initialize user-secrets if needed
$csproj = Get-ChildItem -Filter "*.csproj" | Select-Object -First 1
$csprojContent = Get-Content $csproj.FullName -Raw

if ($csprojContent -notmatch "UserSecretsId") {
    dotnet user-secrets init
    Write-Host "Initialized user-secrets"
}

# Set the secret
dotnet user-secrets set "AzureAd:ClientSecret" $Secret
Write-Host "Stored ClientSecret in user-secrets"

Pop-Location

Step 8: Update Web App appsettings.json

Update the web project's appsettings.json:

{
  "AzureAd": {
    "Instance": "https://login.microsoftonline.com/",
    "TenantId": "<tenant-id>",
    "ClientId": "<web-client-id>",
    "CallbackPath": "/signin-oidc"
  },
  "DownstreamApi": {
    "Scopes": ["api://<api-client-id>/.default"]
  }
}

Note: The ClientSecret is stored in user-secrets, not in appsettings.json.

Existing App Flow

When using an existing app registration (detected from appsettings.json or provided by user), this flow complements it by adding any missing configuration:

Check API Web App
App ID URI (api://{clientId}) ✅ Add if missing —
access_as_user scope ✅ Add if missing —
Redirect URIs — ✅ Add missing URIs
API Permission to call API — ✅ Add if missing
Service Principal ✅ Create if missing ✅ Create if missing

Web App appsettings.json

  "AzureAd": {
    "Instance": "https://login.microsoftonline.com/",
    "TenantId": "YOUR_TENANT_ID",
    "ClientId": "YOUR_WEB_CLIENT_ID",
    "CallbackPath": "/signin-oidc"
  },
  "DownstreamApi": {
    "Scopes": ["api://YOUR_API_CLIENT_ID/.default"]
  }
}

Best Practices

  1. Provision API first — Web app needs the API's Client ID and scope ID
  2. Use .default scope — Safer for downstream API calls in composed scenarios
  3. Store secrets in user-secrets — Never commit secrets to source control
  4. Single tenant by default — Use AzureADMyOrg; switch to AzureADMultipleOrgs only when needed
  5. Parse launchSettings.json — Get accurate redirect URIs for all launch profiles
  6. Complement, don't duplicate — When using existing apps, only add what's missing
  7. Disconnect when done — Run Disconnect-MgGraph after provisioning
