 Running with /v:detailed or higher verbosity will show the various paths that it tries.

+Here the TargetFrameworkDirectory attribute specifies the directory where the assemblies for
+this particular framework can be found. If this is not set, then the parent of the folder
+containing the xml file is taken as the framework directory.
+
+IncludeFramework attribute specifies the version of a framework (under the *same* $(TargetFrameworkIdentifier))
+which should be included in the final list of Target framework directories.
