Add azure application insights

[BenjaminMichaelis]

I have an existing ASP.NET MVC application targeting .NET 9.0.4. Please update the application to integrate Azure Application Insights using OpenTelemetry and the .NET Profiler.
Requirements:

• Install the latest Azure.Monitor.OpenTelemetry.AspNetCore NuGet package.
• In Program.cs, import the Azure.Monitor.OpenTelemetry.AspNetCore namespace and configure OpenTelemetry with builder.Services.AddOpenTelemetry().UseAzureMonitor();.
• Also install and configure the Microsoft.ApplicationInsights.Profiler.AspNetCore NuGet package to enable the .NET Profiler.
• Add builder.Services.AddApplicationInsightsTelemetry(); and builder.Services.AddServiceProfiler(); to enable telemetry and profiling.
• Ensure the application reads the Application Insights connection string from an environment variable named APPLICATIONINSIGHTS_CONNECTION_STRING.
• Make sure logs and exceptions will go to this application insights instance.
• Ensure compatibility with containerized deployment (e.g., Docker), including profiler support.
• Follow best practices from these Microsoft docs:
