New Post: Config files not being removed when uninstalling the package

I have created a NuGet package with spec file similar as shown below.

The issue that I am experiencing is related to the config files not being removed when the package is uninstalled.

As you can see from the spec file, the *.config files have been renamed to *.config.transform because some of the config files may exist already in the project, while the others may not exist. The package installation runs flawlessly in all tested scenarios. The problem that I am experiencing has to do with the *.config files that do not exist in the project before the package is installed. During the installation the corresponding files in the package are renamed back to *.config and added to the project, however these files are not removed when uninstalling the package although their content has not changed.

How can I get the package to delete these remaining config files?
