 Historically one way was to tell Paket that you only want to compile for `framework: net45`.
 However, this doesn't prevent netstandard dependencies in all situations.
 On the other side more features are provided by Paket and the packages folder has become more and more redundant:

+The storage option has three values:

+- `storage: packages` (the default, relevant for FAKE 5 where the default for inline-dependencies is `storage: none`)
+- `storage: none` disable the packages folder and use the global NuGet cache (default in FAKE 5 inline-dependencies)
+- `storage: symlink` use the packages folder but use symlinks instead of physical files
 
 ```paket
 // make a symlink instead copy the packages.
