I've been working on a project template today, first time doing so but it has been going alright. I'm almost finished but have now run into some weird issue I can't figure out.
For some reason which I don't know, whenever I try and debug my project template it is now stuck to using some old version of it. No matter what or how much I change then rebuild and try to debug - it still uses some weird old version stuck in some sort of limbo.
I can't seem to figure out where it's finding this file, I've cleared my temp folder. It doesn't show up as installed when I go to Manage Extensions in Visual Studio.
Any ideas what might have happened? There are no errors or warnings.
I was able to solve this by deleting all files inside %LOCALAPPDATA%\Microsoft\VisualStudio\16.0_cfa111feExp\Extensions. After doing so, I restarted VS and loaded up my project and rebuild (not build) the solution.
After that, it now shows the up-to-date version of the project template. What caused this and how to potentially prevent it in the future - I still have absolutely no idea.
I use Visual Studio 2019 Version 16.4.2
