Something must have been missing in bin/debug, I noticed a permission error while building with VS code. I could fix it by building while running in administrator mode.

I’ve experienced this too, when I created a new project with ASP.NET Core 2.1 and then moved to ASP.NET Core 2.2 (by installing the SDK).

Deleting the obj folder fixed it for me.
