Add Loupe to Your Project

Start by adding the Gibraltar Loupe Agent NuGet package. 

Enable Exception Logging

Add a couple lines to your App class and Loupe will log all unhandled exceptions. 

using System.Windows;
using Gibraltar.Agent;
public partial class App : Application
{
    public App() {
        DispatcherUnhandledException += (sender, e) => {
                Log.ReportException(e.Exception, "Unhandled", true, false);
                e.Handled = true;
            };
    }

    protected override void OnStartup(StartupEventArgs e) {
        Log.StartSession();
        base.OnStartup(e);
    }

    protected override void OnExit(ExitEventArgs e) {
        Log.EndSession();
        base.OnExit(e);
    }
}

TIP: 

Log.ReportException also displays a dialog to the user. If you prefer to silently log exceptions, use Log.RecordException instead.

Add Loupe Server for Exception Reporting

Add a couple more lines and Loupe Server will centralize log collection, analysis and error management. 

<?xml version="1.0"?>
<configuration>
    <configSections>
        <sectionGroup name="gibraltar">
            <section name="server"
                     type="Gibraltar.Agent.ServerElement, Gibraltar.Agent" />
        </sectionGroup>
    </configSections>
    <gibraltar>
        <server autoSendSessions="true"
                useGibraltarService="true"
                customerName="YOUR LOUPE SERVICE ACCOUNT" />
        <!-- If you have an on-premises Loupe Server, use this instead:
        <server autoSendSessions="true"
                useGibraltarService="false"
                server="YOUR LOUPE SERVER" /> -->
    </gibraltar>
</configuration> 

Or you can configure server integration in code

protected override void OnStart(string[] args)
{
    Log.Initializing += Log_Initializing;
    Log.StartSession();
    // ...
}

private void Log_Initializing(object sender, LogInitializingEventArgs e)
{
    var server = e.Configuration.Server;
    server.AutoSendSessions = true;

    server.UseGibraltarService = true; // Using subscription Loupe Service
    server.CustomerName = "YOUR LOUPE SERVICE ACCOUNT";

    // server.UseGibraltarService = false; // Using on-premises Loupe Server
    // server.Server = "YOUR LOUPE SERVER";
}

Ship our Packager Utility along with your application so sessions will be automatically transmitted in the background immediately after your application exits.
