External Libraries

It is recommended to minimize your references to external libraries, because 1 MB of .NET CIL code roughly translates to 3–4 MB of ARM code. For example, if your application references System.dll and System.Xml.dll then it means additional 6 MB of ARM code if stripping is not used. At some point application will reach limit when linker will have troubles linking the code. If you care a lot about application size you might find C# a more suitable language for your code as is has less dependencies than JavaScript.
