Properties

ConflictIDs

Identifiers from a namespace global to all Capabilitys. Collisions in this namespace indicate that the concerned Capabilitys are in conflict cannot be registered on a single system at the same time.

[Browsable(false)]
[IgnoreEquality]
public abstract IEnumerable<string> ConflictIDs { get; }

Property Value

IEnumerable<string>

Remarks

These identifiers are not guaranteed to stay the same between versions. They should not be stored in files but instead always generated on demand.

ID

An ID that differentiates this capability from other capabilities of the same type within the feed. May only contain alphanumeric characters, spaces ( ), dots (.), underscores (_), hyphens (-) and plus signs (+).

public required string ID { get; set; }

Property Value

string

Remarks

Also serves as a programmatic identifier within the desktop environment. In case of conflicts, the first capability listed with a specific ID will take precedence.

WindowsMachineWideOnly

Indicates whether this capability can be registered only machine-wide and not per-user on Windows systems.

[Browsable(false)]
[IgnoreEquality]
public virtual bool WindowsMachineWideOnly { get; }

Property Value

bool
