ManualResetEventSlim

E704381

class managed synchronization construct

ManualResetEventSlim is a lightweight synchronization primitive in .NET used to efficiently signal and wait for events across threads, offering better performance than the classic ManualResetEvent in many scenarios.

How this entity was disambiguated

This entity first appeared as the object of triple T7897482 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07

Target entity: ManualResetEventSlim
Context triple: [System.Threading, containsType, ManualResetEventSlim]

A. ManualResetEvent
ManualResetEvent is a .NET synchronization primitive that allows threads to wait until a signal is set and remains signaled until it is manually reset.
B. AutoResetEvent
AutoResetEvent is a synchronization primitive in .NET used to manage signaling between threads by automatically resetting its state after releasing a single waiting thread.
C. EventWaitHandle
EventWaitHandle is a .NET synchronization primitive that allows threads or processes to signal and wait for events, coordinating execution flow in concurrent applications.
D. RegisteredWaitHandle
RegisteredWaitHandle is a .NET threading class that represents a handle to a registered wait operation, allowing callbacks to be invoked when a WaitHandle is signaled or a timeout occurs.
E. SpinLock
SpinLock is a lightweight synchronization primitive in .NET used to protect shared data by repeatedly checking for lock availability instead of blocking threads.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
