Syntax
public sealed class ImplementationSelection : ImplementationBase, IDependencyContainer, IInterfaceUriBindingContainer, IInterfaceUri, IBindingContainerRemarks
This class does not contain information on how to download the implementation in case it is not in cache. That must be obtained from a Implementation instance.
Constructors
ImplementationSelection()
Used for XML serialization.
Declaration
public ImplementationSelection()ImplementationSelection(IReadOnlyList<SelectionCandidate>)
Creates a new implementation selection.
Declaration

|---|---|
| String |
FromFeed
The URL or local path of the feed that contains this implementation.
FromDistributionPrefix is prepended if data is pulled from a native package manager.

QuickTestFile
A file which, if present, indicates that the selection is still valid. This is sometimes used with distribution-provided selections. If not present and the ID starts with "package:", you'll need to query the distribution's package manager to check that this version is still installed.
