Logging MediatR Requests

With the MediatR v3, there is the ability to create your own request pipelines. To help out of the box, there are some predefined behaviors to help out with commen tasks such as pre and post request. These are RequestPreProcessorBehavior<,> and RequestPostProcessorBehavior<,> I’ve blogged about the new behaviors before but you can do it more generically.

This entire week I’ve almost exclusively used Rider.  I’ve used some of the early EAP’s, but not on an actual project. One of the first roadblocks I hit was trying to figure out how to launch multiple projects from my solution. Thankfully, it didn’t take me too long to figure out.

Lazy Async

I’ve been moving some data access code to to use Lazy<T> whenever I want to defer actually fetching the data until it’s first needed.  What I’ve always found interesting is there is no Lazy Async. In the exact use case it’s when an application loads, there is some static data loaded from a database.  This data is the cached for later use. However, in many situations it’s not actually needed until much later if at all.  Why take the performance hit of fetching the data on app startup if that data is often times not needed? That’s the whole purpose… Read More »Lazy Async
