People have rightly mentioned the cost and vendor lock-in issues. The other problem is that - for whatever reason - good engineers simply want nothing to do with the Microsoft ecosystem. In this market, they have other options. So tying your infrastructure to .NET means limiting your hiring pool to mostly 9-to-5er enterprise developers who tend to fix problems by asking Microsoft to sell them the solution. Not exactly the attitude you want at a startup.
