Visual Studio Community Edition - Download Latest Free Version
The final words on the matter come from the linked page: https://visualstudio.microsoft.com/vs/community/
Quoted from the lower portion of the above linked page:
Usage
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.
I hope that is official enough words from Microsoft to ease any legal concerns about using Community Edition for paid apps, by an individual, a sole proprietor, or a few members of a partnership.
