i just to ask about things from visual studio community. I made a software build in c# and a small company wants to buy my software, i am using visual studio community 2015 and ms sql express. Just want to ask if do i need to get a license for my software specifically for microsoft license or .net license? And any legal action? thank you
The Terms and Conditions of Microsoft are very clear on the topic.
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.
However another clause seems to come into effect with you.
Any individual developer can use Visual Studio Community to create their own free or paid apps.
In both cases, it would seem you qualify to use Visual Studio Community edition however you see fit.
