GetIntegrationAsync(FeedUri, Boolean)

Returns the desktop integration categories that are currently applied for a specific feed.

Declaration

Task<ISet<string>> GetIntegrationAsync(FeedUri uri, bool machineWide = false)

Parameters

Type	Name	Description

Returns

Type	Description
ProcessStartInfo

IntegrateAsync(FeedUri, IEnumerable<String>, IEnumerable<String>, Boolean)

Adds an application to the application list (if missing) and integrates it into the desktop environment.
