Windows.ApplicationModel.Package.IsOptional

-description

Indicates whether the package is optional.

-examples

// Get the main app package
Package currentPackage = Package.Current;

// Get a list of dependencies for the main package. This includes all resource packages, framework packages, and optional packages.
IReadOnlyList<Package> dependencies = currentPackage.Dependencies;

foreach (Package package in dependencies.Where(_ => _.IsOptional))
{
    // Iterate through a list of the optional packages
}
