I know that DI(dependency injection) is probably just another good pattern out there like many others, but dear lord have I been burned on it with acumatica. Acumatica just loves having friggen magic crap everywhere with no damn explanation(*may be in a blog post somewhere but that’s no replacement for good documentation).

I believe they use AutoFac in C# on an asp.net server. They love to utilize reflection and injection and in turn the server takes multiple minutes to startup whilst it dynamically registers everything, as well on any individual pages.

Development is a pain in the ass on this damn system.

I’m constantly having to dive into the damn code using dotpeek to understand what the fuck they are doing and it’s often friggen stupid shit. They like to reinvent the wheel a fair bit.
