Microsoft .net and XSLT 2

Greetings,

Sorry if this is off-topic ...

Is anyone using Microsoft's .Net with XSLT 2?  

My problem is I am developing some XSL stylesheets testing with the latest
Saxon and now I need to develop the application.

I keep running across things like this:

...which makes me think that Microsoft isn't going to adopt XSLT 2.

Thanks,
Jim Neff
