If I set up my WCF project with an ApplicationInsights.config file as outlined in this Microsoft documentation, and data is logged to Application Insights (using the hardcoded instrumentation key) as expected.
The config file looks like this:
<?xml version="1.0" encoding="utf-8"?>

My web.config contains the following:
<system.web>
<compilation debug="true" targetFramework="4.7.2" />
<httpRuntime targetFramework="4.7.2" />
<httpModules>
<add name="TelemetryCorrelationHttpModule" type="Microsoft.AspNet.TelemetryCorrelation.TelemetryCorrelationHttpModule, Microsoft.AspNet.TelemetryCorrelation" />
<add name="ApplicationInsightsWebTracking" type="Microsoft.ApplicationInsights.Web.ApplicationInsightsHttpModule, Microsoft.AI.Web" />
</httpModules>
</system.web>
This documentation suggests that I can set the instrumentation key in code (such as in an AppInitialize method as suggested by this answer), but it doesn't seem to work.
TelemetryConfiguration configuration = TelemetryConfiguration.CreateDefault();
configuration.InstrumentationKey = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx";
While there appear to be some caveats to this solution (depending on your hosting strategy), it is sometimes possible to add a Global.asax, and use the Application_Start hook to inject your configuration (This answer assumes you're using config transforms).
For example:
using System;
namespace SomeWcfThing
{
public class Global : System.Web.HttpApplication
{
protected void Application_Start(object sender, EventArgs e)
{
Microsoft.ApplicationInsights.Extensibility.TelemetryConfiguration.Active.InstrumentationKey =
System.Configuration.ConfigurationManager.AppSettings["InstrumentationKey"];
}
}
}
