A domain primitive base class makes declaring domain primitives a breeze.
My Take On Domain Primitives

Use Collection Initializers To Simplify Tedious Mapping and Validation Tests
With custom collection initializers, you can avoid writing repetitive test methods for mappers, converters and validators by using parameterized tests with type-safe yet generic test samples based on expressions and corresponding values.
Simplifying unit tests for WPF ViewModels
Use custom assertion extensions to easily unit-test implementations of INotifyPropertyChanged.
Improve your parameterized Tests with named ValueTuples
For parameterized tests, declare your samples as value tuple array and subsequently "Select" it to IEnumerable to be type-safe, concise and descriptive.

Performance Optimization Guided By Benchmarks
This post is just a summary of a few things I learned about performance optimization of CPU-bound / memory-bound processes in C#/.NET.
I was able to accelerate two different low-level image processing algorithms by a factor of 10 while learning a lot and enjoying the process.
