I just activate my visual studio 2017 license today (I've got one license from MSDN)
And I wanna know if I can share the license key with friends like a VL (volume license) or no ?
Thank in advance
No. Your MSDN subscription licenses you (and only you) to use Visual Studio (emphasis mine)
Visual Studio subscriptions (formerly called MSDN subscriptions) are licensed on a per-user basis. One person can use the software to design, develop, test, or demonstrate his or her programs on any number of devices. Source
However, there is Visual Studio Community Edition that lone developers are entitled to use. Companies that have 5 or less developers can also make use of this edition without breaching the EULA.
For Individuals
Any individual developer can use Visual Studio Community to create their own free or paid apps.For organizations
An unlimited number of users within an organization can use Visual Studio Community for the following scenarios: in a classroom learning environment, for academic research, or for contributing to open source projects.For all other usage scenarios: In non-enterprise organizations, up to five users can use Visual Studio Community. In enterprise organizations (meaning those with >250 PCs or >$1 Million US Dollars in annual revenue), no use is permitted beyond the open source, academic research, and classroom learning environment scenarios described above.
