Discovering C# exception filters

An older language feature I'd not noticed

There's been a lot going on with language development in C# over the last couple of years. But despite all the current change for things like record types and generic maths, there are some changes from older versions that I somehow missed. This week social media put me on to the concept of contextual filters for exception handling. What's that? Read on...

Hosting ASP.Net Core 7 Preview 7 under IIS

Regular Expression improvements in .Net 7

I've spent a bit of time looking at how Regular expressions are changing in the upcoming .Net 7 release.

It's never the runtime... (Except when it is)

Bug Something I've learned over the course of many years working in IT is that when you hit a difficult to explain problem it's very easy to say "it's the runtime's fault!" or "that's a compiler bug" to cover for the lack of explanation for your problem. The vast majority of the time, it's not true though. It's just a subtler bug in your own work that you can't see yet.

Every so often, however, it is true. And it turns out the issue I discussed the other week about Sitecore rendering a Razor error when you asked for a media item may well be an example of this.
