I’m sure one of the first exceptions any of us get as C# devs is when we try to iterate over a List (or other enumerable) and attempt to remove an item. This results in the exception: InvalidOperationException was unhandled. Collection was modified; enumeration operation may not execute. The easy solution is just to create […]

Arguably one of the biggest parts of .NET 4.0 was the Task Parallel Library (TPL). The TPL makes it ridiculously easy to parallelize code. With Parallel.ForEach, Parallel.For, Parallel.Invoke, and Task.Factory developing for today’s multi-core systems should be a matter of fact. Recently I was tasked with optimizing a large code base to utilize the TPL. […]

Update 2024-02-17: It’s kind of funny rereading this considering lately I’ve been doing a bunch of Maui dev. Okay, for the first time ever I’m a bit jealous of iPhone users.(See below) Novel (the sponsor of Mono) has released the MonoTouch, a C# and .NET development platform for the iPhone. Granted it’s $400 for the […]

Update 2023-02-17 – I’ve updated the link to the most version of the code discussed here. The post is based on the original code, which has been superseded. As such it’s no longer applicable. Please follow the link and read the updated code. Recently I came across ACM’s Software Engineering Code of Ethics and Professional […]

Between keeping up with what’s coming for .Net 4.0 as well as the end of a large DOD contract I’ve been a bit busy (and no developer fatigue, just busy :)). But don’t fret loyal readers, more will be coming soon. Until then here is a bit of xaml for self-referencing bindings. As you can […]
