Core Workflows

1. Create Application Insights Component (Workspace-based)

using Azure.ResourceManager.ApplicationInsights;
using Azure.ResourceManager.ApplicationInsights.Models;

ResourceGroupResource resourceGroup = await client
    .GetDefaultSubscriptionAsync()
    .Result
    .GetResourceGroupAsync("my-resource-group");

ApplicationInsightsComponentCollection components = resourceGroup.GetApplicationInsightsComponents();

// Workspace-based Application Insights (recommended)
ApplicationInsightsComponentData data = new ApplicationInsightsComponentData(
    AzureLocation.EastUS,
    ApplicationInsightsApplicationType.Web)
{
    Kind = "web",
    WorkspaceResourceId = new ResourceIdentifier(
        "/subscriptions/<sub-id>/resourceGroups/<rg>/providers/Microsoft.OperationalInsights/workspaces/<workspace-name>"),
    IngestionMode = IngestionMode.LogAnalytics,
    PublicNetworkAccessForIngestion = PublicNetworkAccessType.Enabled,
    PublicNetworkAccessForQuery = PublicNetworkAccessType.Enabled,
    RetentionInDays = 90,
    SamplingPercentage = 100,
    DisableIPMasking = false,
    ImmediatePurgeDataOn30Days = false,
    Tags =
    {
        { "environment", "production" },
        { "application", "mywebapp" }
    }
};

ArmOperation<ApplicationInsightsComponentResource> operation = await components
    .CreateOrUpdateAsync(WaitUntil.Completed, "my-appinsights", data);

ApplicationInsightsComponentResource component = operation.Value;

Console.WriteLine($"Component created: {component.Data.Name}");
Console.WriteLine($"Instrumentation Key: {component.Data.InstrumentationKey}");
Console.WriteLine($"Connection String: {component.Data.ConnectionString}");

2. Get Connection String and Keys

ApplicationInsightsComponentResource component = await resourceGroup
    .GetApplicationInsightsComponentAsync("my-appinsights");

// Get connection string for SDK configuration
string connectionString = component.Data.ConnectionString;
string instrumentationKey = component.Data.InstrumentationKey;
string appId = component.Data.AppId;

Console.WriteLine($"Connection String: {connectionString}");
Console.WriteLine($"Instrumentation Key: {instrumentationKey}");
Console.WriteLine($"App ID: {appId}");

3. Create API Key

ApplicationInsightsComponentResource component = await resourceGroup
    .GetApplicationInsightsComponentAsync("my-appinsights");

ApplicationInsightsComponentApiKeyCollection apiKeys = component.GetApplicationInsightsComponentApiKeys();

// API key for reading telemetry
ApplicationInsightsApiKeyContent keyContent = new ApplicationInsightsApiKeyContent
{
    Name = "ReadTelemetryKey",
    LinkedReadProperties =
    {
        $"/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/microsoft.insights/components/{component.Data.Name}/api",
        $"/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/microsoft.insights/components/{component.Data.Name}/agentconfig"
    }
};

ApplicationInsightsComponentApiKeyResource apiKey = await apiKeys
    .CreateOrUpdateAsync(WaitUntil.Completed, keyContent);

Console.WriteLine($"API Key Name: {apiKey.Data.Name}");
Console.WriteLine($"API Key: {apiKey.Data.ApiKey}"); // Only shown once!

4. Create Web Test (Availability Test)

WebTestCollection webTests = resourceGroup.GetWebTests();

// URL Ping Test
WebTestData u
