KeyedLocks

Sync and async locking based on a key

Usage

This library provides the KeyedLock<T> type, which can be used like this:

var locks = new KeyedLock<string>();
using (locks.Lock("key"))
{
    //Do the important thing
}

The using block ensures that the lock will be released after.

In async code, you can also wait to acquire the lock asynchronously:

var locks = new KeyedLock<string>();
using (await locks.LockAsync("key"))
{
    //Do the important thing
}

Testing

KeyedLock<T> is internally based on a Dictionary<T, SemaphoreSlim>. Semaphores are created and destroyed as needed.

This code has been tested with Microsoft Coyote to try to eliminate concurrency bugs.
