.net: How to clean up corrupted assembly being referenced? - windows

Question

I shut down computer without closing running programs. Now when I run my application on localhost, I'm getting the following error:
Could not load file or assembly 'FluentValidation' or one of its dependencies.
The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))
I've find this article, which explains that I need to cleanup the temporary folder.
I'd like to know what the meaning of cleanup in this case: Just select files in the folder and delete them? I don't want to mess up with my computer.
Thanks for helping.
