<AutoGenerateBindingRedirects> doesn't work for class libraries

The property is ignored unless the containing project is an .exe.

Extensible frameworks/apps that load plugins might support loading configuration for each plugin, including binding redirects, from a .dll.config file next to the plugin .dll. For example, a unit-testing framework such as xunit. See also proposal https://github.com/Microsoft/msbuild/issues/1309, which might also make use of this feature.

I propose the restriction on project type is removed and binding redirects are generated for any project that sets AutoGenerateBindingRedirects to true.
