Getting started - It's quick and easy


Add code snippets

The following instructions will integrate Raygun with a vanilla .NET console application written in C#.

The best way to get Raygun is to install the NuGet package. With the NuGet Visual Studio extension installed, right-click on your project and select "Manage NuGet Packages..." Make sure "Online" is highlighted in the left hand pane, then use the top right search box to find Mindscape.Raygun4Net and install it.

Alternatively, visit https://nuget.org/packages/Mindscape.Raygun4Net/ for instructions on installation using the package manager console.

Instantiate the client and hook up the unhandled exception delegate:

static RaygunClient _client = new RaygunClient("Your_API_Key");
public static void Main(string[] args)
  AppDomain.CurrentDomain.UnhandledException += CurrentDomain_UnhandledException;
  // Your code here
private static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
  _client.Send(e.ExceptionObject as Exception);

.NET Error Monitoring Features

Raygun gives you full stacktraces for each and every error occurrence, along with environment information, HTTP requests, raw data, browser, OS, affected users and more. All the details you need to rectify issues quickly and efficiently. Raygun stores every single error event (no data sampling) so you’ll always have the right information at hand when needing to see when, why and how an error occurred.

  • Rather than be bombarded with a flood of messages and error emails, Raygun silently monitors your applications in the background and offers smart alerts for you when need to take action. Notifications are fully customizable, but repeating error instance emails and team chat alerts are sent only when issues are recurring or getting worse, resulting in more signal, and less noise.
  • Raygun allows you to set inbound filters to remove the reporting of errors you don’t care about or cannot fix, meaning you’ll be able to see the problems that are highest priority and affecting the largest amount of users. Choose what you want to monitor with custom setup for dealing with private user details and sensitive information, you can do it all.

It takes minutes to set Raygun up - seriously

Simply add a short .NET code snippet and deploy your application into production, that’s all you need to start monitoring your application for .NET errors. Start fixing bugs within minutes!
