No.
If I remember correctly, bitcoin core's mining capabilities have been removed or disabled due to the improfitability of normal cpu and gpu mining. Your best bet would be to somehow enable it (if possible) or install a different mining application.
The CPU miner was removed, the GPU (and ASIC) miner was never there.
I have a ASIC miner ... I was wondering ..
Can i just plug this in and use bitcoin core to mine by myself?
No. You will need a software which you must run your ASIC using. Some ASICs provide this interface on their firmware while some ASICs don't so you would have to use softwares like Cgminer.
I have watched some tutorials but those were all old version .
Bitcoin Core does not support stratum so you need a software that can support getwork. Else, you need a stratum proxy to convert the getwork to stratum.
You need these in bitcoin.conf:
-server
-rpcuser=[Whateverusername]
-rpcpassword=[Yourpassword]
-rpcallowip=[the local IP your miner is connecting from]
-rpcport=8332
You should consider going for ck's solo pool since that is far easier to use:
