[SOLVED] Activator.CreateInstance Performance Alternative

Issue

I’m using RedGate to do some performance evaluation. I notice dynamically creating an instance using Activator.CreateInstance (with two constructor parameters) is taking a decent amount of time… is there a better alternative that still utilizes a reflective approach (not explicit instantiation)?

Solution

Use a compiled lambda if you can, its MUCH faster.
