user83247: This is a repost of (JSON-RPC signrawtransaction returns false when using private keys) but I could not comment because of my reputation (new user).
I've been using BitcoinLib via Litecoin Testnet for a week now and I got stuck with SignRawTransaction. It returns false but when I use the RPC call via litecoin-cli
litecoin-cli.exe signrawtransaction 020000000152cf5e76f1ac0fd42e97ec60db30406b019621da497601b430e7adf5642e1fa20000000000ffffffff02e09c4100000000001976a914fbb4b6ef02914490e99f899cb8538b03105331df88acc095a905000000001976a91471efff92af2740dd4fe088fc3de98ceebaa4c13488ac00000000 "[]" "[\"cQ3HSi45qrfGGZjYAci22gATWfhb1QhWR8JGBHBbzbPsD8Uuu2n2\"]"

the result is OK.
This is how I use the SignRawTransaction (Sample):
SignRawTransactionRequest signRawRequest = new SignRawTransactionRequest("020000000152cf5e76f1ac0fd42e97ec60db30406b019621da497601b430e7adf5642e1fa20000000000ffffffff02e09c4100000000001976a914fbb4b6ef02914490e99f899cb8538b03105331df88acc095a905000000001976a91471efff92af2740dd4fe088fc3de98ceebaa4c13488ac00000000");
signRawRequest.AddKey("cQ3HSi45qrfGGZjYAci22gATWfhb1QhWR8JGBHBbzbPsD8Uuu2n2");

SignRawTransactionResponse signRawResponse = coinService.SignRawTransaction(signRawRequest);

Has anyone encountered this problem before? 

user83247: I'm sorry but there were missing inputs when I created my Raw transaction. This error has nothing to do with BitcoinLib.
