user38794: My concern is about miner's fee, who is taking that amount? Blockchain.info or NBitcoin? I just wanted to confirm whether the library internally uses blockchain.info apis for performing transactions.

user24974: No, NBitcoin does not use Blockchain.info's API in order to interact with the Bitcoin blockchain.  It implmenents the Bitcoin scripting language, network protocol, transaction construction, and other aspects.  This allows programmers to use NBitcoin to directly interact with the Bitcoin network.
Since transaction construction is in the hands of the NBitcoin user, transactions can be constructed with whatever miner fees you choose.
