I actually had a lot of fun building a native .NET web frontend in VB 2005 recently lol. I thought it kind of amazing that i could just bind UI controls directly to state objects and the UI would automatically React to any changes i made. Felt very natural as a modern web dev lol. Found a lightweight .NET JSON library that was compatible all the way back to VB 2005 as well.

In case you also need to control Spotify from Windows 95 :D
