Detailed Description

Temporarily restores a captured SynchronizationContext for the current async flow.

Layer 2 (host loop). Wrap the full host-loop-dependent body of grabber Grabbers.IFrameGrabber.OpenAsync in this scope. Use SourceToMatHostMarshaling.ResolveCapturedSynchronizationContext for the captured argument.

Host-loop ticks via SourceToMatHostWait or SourceToMatHostMarshaling.YieldCapturedSynchronizationContextAsync run inside this scope (or a nested scope when an inner await may clear SynchronizationContext.Current).

When captured is null, the scope is a no-op (nothing is saved or restored). Prefer constructing grabbers on the host main thread so a non-null context is captured.

Always dispose (for example using) so SynchronizationContext.Current is restored. Nesting is supported: each scope saves and restores its own previous context.

(

SynchronizationContext

captured

)

Parameters

captured

Synchronization context captured on the main thread; null makes the scope a no-op.
