Wow, Microsoft has come a long way:
MICROSOFT VISUAL STUDIO COMMUNITY 2015
These license terms are an agreement between Microsoft Corporation (or based on where you live, one of its affiliates) and you. They apply to the software named above. The terms also apply to any Microsoft services or updates for the software, except to the extent those have different terms.
IF YOU COMPLY WITH THESE LICENSE TERMS, YOU HAVE THE RIGHTS BELOW.
- INSTALLATION AND USE RIGHTS.
- Individual license. If you are an individual working on your own applications to sell or for any other purpose, you may use the software to develop and test those applications.
- Organization licenses. If you are an organization, your users may use the software as follows:
- Any number of your users may use the software to develop and test your applications released under Open Source Initiative (OSI) approved open source software licenses.
- Any number of your users may use the software to develop and test extensions to Visual Studio.
- Any number of your users may use the software to develop and test your applications as part of online or in person classroom training and education, or for performing academic research.
- If none of the above apply, and you are also not an enterprise (defined below), then up to 5 of your individual users can use the software concurrently to develop and test your applications.
- If you are an enterprise, your employees and contractors may not use the software to develop or test your applications, except for open source and education purposes as permitted above. An “enterprise” is any organization and its affiliates who collectively have either (a) more than 250 PCs or users or (b) more than one million US dollars (or the equivalent in other currencies) in annual revenues, and “affiliates” means those entities that control (via majority ownership), are controlled by, or are under common control with an organization.
- Demo use. The uses permitted above include use of the software in demonstrating your applications.
The license continues, but the above are the most important aspect to verify if you can use Visual Studio 2015 under that license.
