As someone who has done a lot of work with .NET in a past life, I think the main reason that more startups aren't using it are for culture reasons. .NET's move into open source is fairly recent and I'd expect more startups to use it (if it fits) in the future.

Most startups are trying to build products with a low budget overhead and previously that was a lot harder to do in the .NET ecosystem.

I think it's because the standard/native database backend is SQL Server which costs money. Yes, you can easily develop against other RDBMS but most .NET shops stick with a pure Microsoft WISC stack.

IIS (Internet Information Services)

Is it culture? Or is it just that the JVM does the same thing, but with a bigger and older ecosystem, with more experienced people etc. Lots of startups out there using Java or JVM languages.
