VersionTelemetryInitializer

VersionTelemetryInitializer sets the TelemetryContext.Component.Version property to your application's version. The default constructor will use the version of the entry assembly (your main executable).

    TelemetryConfiguration.Active.TelemetryInitializers
        .Add(new VersionTelemetryInitializer());

You can explicitly specify the version by passing it into the constructor:

    TelemetryConfiguration.Active.TelemetryInitializers
        .Add(new VersionTelemetryInitializer("1.0.0"));

You can also pass in an assembly or type in that assembly to derive the version from. In this case, it will use the AssemblyName.Version property as the application version:

    TelemetryConfiguration.Active.TelemetryInitializers
        .Add(new VersionTelemetryInitializer(Assembly.Load("MyApi")));

or

    TelemetryConfiguration.Active.TelemetryInitializers
        .Add(new VersionTelemetryInitializer(typeof(Startup)));

Http4xxSuccessTelemetryInitializer

Http4xxSuccessTelemetryInitializer sets the RequestTelemetry.Success property to true if the response code is in the 4xx range. Specifically, >= 400 and < 500. By default, the Application Insights SDK sets this property to false for 4xx codes. If you're using 4xx codes for valid business responses, such as a 404 when a given entity isn't found, then this can create noise.

    TelemetryConfiguration.Active.TelemetryInitializers
        .Add(new Http4xxSuccessTelemetryInitializer());
