How would I do the equivalent of 'in_dir=s' => \@in_dirs from Perl's Getopt::Long, i.e., a case where --in_dir was used multiple times.

Manually, by capturing values in an intermediate list:

var dirs    = new List<string> ();
var options = new OptionSet {
    { "in_dir=", v => dirs.Add (v) },
};
var unmatched = options.Parse(new[]{

"--in_dir", "A",

Installation of Native Libraries

An Android .apk file can contain native libraries for one or more architectures. Historically, all native libraries for the target device are extracted at .apk installation time. This would result in two copies of native libraries on the target device: a set of native libraries which are stored compressed within the .apk, and a separate set of native libraries on the Android target filesystem.

Starting with Android v6.0 (API-23), Android added an ability for

Binding Java 8 Interfaces from C♯

Help wanted! :-)

Background

Xamarin.Android binds the Android Java API, which means that all Java language features need to be "bound" to corresponding C# language features. For many language constructs, this binding is simple, e.g. type names are (usually) unchanged and identical, while other language features are changed in subtle
