var cacheExpirationOptions = new MemoryCacheEntryOptions 
{
    AbsoluteExpiration = DateTime.Now.AddMinutes(5),
    Priority = CacheItemPriority.Normal,
};
_memoryCache.Set(fakeTransactionId, transaction.Id,
    cacheExpirationOptions.RegisterPostEvictionCallback((key, value, reason, state) = > {
        TransactionStatusUpdate(transaction.Id, TransactionStatusType.UrlExpired);
    }));

I want to update the process when the default process expires, what should I do?

var expirationTime = DateTime.Now.AddMinutes(30); var expirationToken = new CancellationChangeToken( new CancellationTokenSource(TimeSpan.FromMinutes(31)).Token); var cacheEntryOptions = new MemoryCacheEntryOptions() .SetPriority(CacheItemPriority.NeverRemove) .SetAbsoluteExpiration(expirationTime) .AddExpirationToken(expirationToken) .RegisterPostEvictionCallback(callback: EvictionCallback, state: this); _memoryCache.Set(fakeTransactionId, transaction.Id, cacheEntryOptions);
