One is that C# has partial classes but F# does not. This comes up for all the XAML tooling that C# supports but F# doesn't. Also, F# only has null for use in certain situations only for interoperability. There are others that I've seen but don't know off the top of my head. I think they are usually OOP related and at the edges. I don't much know them because I don't really know C#.
