I don't doubt it, but I don't run Microsoft software any more. I've seen enough embrace, extend, and extinguish in my lifetime to not depend on them for my code's execution environment.

My current work needs nothing the .NET environment provides that I can't use python's standard libraries to get done, or bash and C if I need to.

But I'm lucky to no longer be in a corporate environment, so I don't need to consume commercial services, which was much easier using WCF within .NET. Back in my previous life, constructing n-tiered services on top of SqlServer using WCF was slick, indeed.

To any who are interested in how to construct such n-tiered applications simply but securely and precisely, I highly suggest Juval Lowy's IDesign system. He had three specific videos that I watched three or four times each until I understood his distillation of his vast expertise. Of course, Mr. Lowy is one of the co-designers of WCF, which was an excellent bit of tech.

FWIW, F# is an open source project controlled by the F# Software Foundation, the .NET Foundation, and Microsoft.
