Part of implementing an error monitoring platform like elmah.io is dealing with the IP addresses of the clients generating errors. In this post, I'll show you parts of how we have implemented this in ASP.NET Core, to make sure that different hosting scenarios still produce the correct IP ...

Someone asked me about the possibility of turning on a light on new errors logged to elmah.io the other day. While we offer dashboards to put on a big screen in the office, I hadn't thought much about turning physical things on and off on errors. This sounded like ...

We have a couple of internal websites hosted on Azure. Websites that require authentication and should only be accessed from our IP. This can easily be configured using Access Restrictions in Azure. But when doing so, you exclude the dynamic IP range for Microsoft-hosted Azure DevOps build agents. In this ...

While most of my time goes into elmah.io, I love working on side projects too. Like the NuGet package updater tool NuPU and the Dark Screen of Death Chrome extension. A few weeks ago, I felt the need to solve a small problem I've had understanding Cron expressions. The ...

While developing elmah.io support for WPF, I had the chance to look into WPF for the first time in many years. I couldn't stop myself from digging down into all sorts of details about how logging has evolved in WPF since I last wrote a WPF app. In this ...

A friend of mine asked me how we build and publish our Visual Studio extension. His initial thought was that the process is manual and since the code is in a private repository, here's a quick walkthrough of building and publishing Visual Studio extensions with GitHub Actions. Before I start ...

I have been building a feature on elmah.io lately that picks up validation results from an external API. Before serverless was a thing, I would probably have done this using a scheduled task or Windows Service using Hangfire or similar. But after having migrated everything to serverless Azure Functions, ...

Chrome revolutionized the way to extend browsers with new features. Back in the day, extensions were annoying toolbars (remember the Ask toolbar?) and related spam-like additions. Today, I couldn't live without extensions. Here's a list of our favorite extensions used while developing elmah.io. Let's jump right into the extensions. ...
