Sometimes, you can make changes using Visual Studio (at this point, I’m still using VS 2010), but when you run the app for debugging, the changes don’t appear. This may then be a cache issue, but it’s very easy to fix.

All you do is navigate to:

c:\Users\<username>\AppData\Local\Temp\VWDCache

Then, either delete that folder (it will get regenerated the next time you run VS), or delete all the items in it.
