Spend two years putting your heart into rebuilding our internal WinForms apps in WPF to modernize and have something more agile (and fun) to work with, just to be told that the Board has decided to replace all of it with a third party system because our own stuff can't give them the economic reports that they're used to. Fml.

That does not seem fair. If you learned while doing the project take it as a positive.
Welcome and glad you found devRant!

Thanks!
Yeah, of course the whole process was a great experience and I appreciate how I got to learn a new platform and all that, it's just that I finally was getting close to where I wanted to be with these apps and was really looking forward to see where we could go from here, and that's when they decide to throw it all in the bin for some bs reason.
I guess I also learned not to get too personally invested in company software :P
