Since I last posted, my wife and I have bought a new home, moved, sold our previous home, and ran the Chicago marathon. All while getting up the learning curve and taking on more responsibility at our new jobs (both started in June). Needless to say, I’ve had no time for tech blogging. Until now. OK, let’s get to it: Dapper is a great micro-ORM library. It’s simple and highly performant. I love its Multi-Mapping feature, which simplifies mapping columns from a SQL result set into multiple object types. It has an annoyance though: The lambda method provided by the […]
