StackExchange.Redis LockTake & Lock Release -

i using the following code redis lock , release

var key = "test-x"; redisvalue token = (redisvalue) guid.newguid().tostring(); if(db.locktake(key, token, duration)) {     try {         // have lock work     } {         db.lockrelease(key, token);     } } 

my problem:

in unit test calling method 2 times. first time work, second time want obtain lock on specific key, not work. understanding db.lockrelease should release lock, making available second request. i did notice db.lockrelease returns false.

any idea might happening?

the lock key needs unique. using same lock key cache key in code. https://stackoverflow.com/a/25138164:

the key (the unique name of lock in database)
