[Windows.Foundation.Metadata.Overload("TryGetValue")]
public ResourceCandidate TryGetValue(string resource);

function tryGetValue(resource)

Remarks

Some resources are loaded according to the scale of the view where they will be displayed, and different views within an app might be displayed on different devices with different scales. Scale is a per-view characteristic.

Since the TryGetValue method selects the best candidate for the specified resource in relation to a runtime context, and since the scale qualifier of a ResourceContext depends on the associated view, TryGetValue should always be called with a ResourceContext object obtained from the view in which the resource will be used.
