Adding Application Insights to .NET MAUI Application

This article provides an in-depth exploration into how you can integrate Microsoft's Application Insights into your .NET MAUI application. A comparative study between Microsoft AppCenter and Application Insights is also highlighted, demystifying the inherent advantage of Application Insights in application management and analytics.

The constructor is taking in a parameter of type ILogger and assigning it to the private variable of the same name but I don't see anywhere where this constructor is called with that argument. If you were to create a default constructor then logger will not be defined and it's obviously going to throw an exception. Where does logged come from?

[VladislavAntonyuk]

From DI. See MauiProgram where we register logger

[iPaul-777]

Do you have a MauiProgram.cs example that initializes MyService() as shown above?
This code does not initialize MyService():
builder.Logging.AddApplicationInsights(configuration =>
{
configuration.TelemetryInitializers.Add(new ApplicationInitializer());
configuration.ConnectionString = "YOUR-CONNECTION-STRING;
}, options =>
{
options.IncludeScopes = true;
});

Of course, this code registers ApplicationInsights logger. MyService can be registered as:

builder.Services.AddSingleton<MyService>();

The full sample is available. See the link in the bottom of the article.
