These are just some of the more popular projects I have worked on in my personal development time.
A very generic .editorconfig file supporting .NET, C#, VB and web technologies.
Log exception details and custom properties that are not output in Exception.ToString().
Schema.org objects turned into strongly typed C# POCO classes for use in .NET. All classes can be serialized into JSON/JSON-LD and XML, typically used to represent structured data in the head section of html page.
Big-O complexities of common algorithms used in .NET and Computer Science.
.NET project templates with batteries included, providing the minimum amount of code required to get you going faster.
