I'm currently developing a web app on Django/Python, and I consider moving to ASP.NET MVC. I downloaded the Visual Web Developer Express edition, read NerdDinner, and I'm ready to go. I will probably keep working on MySQL.
One of the reasons I chose Django+MySQL in the first place was that it was free of charge. I'm bootstrapping a business and can't afford to pay for expensive software, even for deployment (storage and bandwidth are the exception).
My question is: can I develop on the express edition and get my product to production without having to pay to Microsoft? This is both a legal question and a practicality question (Assume I'll use open source version control, build server, etc).
I'm not experienced in Microsoft's different licenses, I wondered if anyone has any experience in driving a product to the web based solely on the express editions (I know you guys are not lawyers, but some of you are probably working at companies paying lawyers to help with such decisions...)
