✅ How to solve "[MyType] cannot be cast to [MyType] due to different assembly versions.

This is due to my lack of knowledge around how Visual Studio manages references, I think. I have a custom Controls library. I store this on a personal NuGet and update any projects that depend upon it via the NuGet package manager. Recently, When I drag a specific custom control onto a form, I get the attached error. I tried uninstalling the library, cleaning solution then re-installing the library - same error. Where the hell are these different versions stored and why? How do I fix this?

Forget it - I forgot to restart Visual Studio 🤣 Gotta love the lumbering, idiosyncratic beast!
