@mqudsi so, one question in AsyncLock class has member IDisposable Lock and Task<IDisposable> LockAsync which name would be better to take for function returned IAsyncDisposable и Task<IAsyncDisposable>

We wouldn’t add a new function to expose that; it would require instead adding a type that implements both IDisposable and IAsyncDisposable, which is unfortunate.
