Remarks

Enables Windows Runtime APIs that use significant amounts of native memory to signal their memory footprint to garbage-collected (GC) environments, like JavaScript and .NET Framework. Applying the GCPressureAttribute enables efficient scheduling of garbage collection sweeps.

GC environments explicitly ignore the attribute on Windows Runtime objects that are outside of the Windows namespace.

Constructors

GCPressureAttribute()

Creates and initializes a new instance of the attribute.
