Some methods can't be used in other C#

[dvnguyen-uofa]

I used FsMath3D in my C# project. I can use vec2, vec3 structures. However, when I try to do some transforms. VS couldn't recognize the methods of Transform class at all. Turn out that the class has method with dot (.) in its name, I think:

I didn't try to use it in C# before, will test and see what's going on. I d suspect how F# encodes methods (everything is allowed) vs C# (stricter).
