As Tianyu says, the visual studio 2012 is too old, and as far as I know, there is no subscription service for it. If you want to use visual studio all the time, we suggest you could usevisual studio 2017 or visual studio 2019. They have free version which is VS community. It is for individual developer. In addition, you want more enterprise features, we recommend you could buysubscription for VS professional and VS enterprise. Then you could use it with your team and big projects better.
