With UWP, Visual C++ kind of finally caught up with C++ Builder, it even has support from Blend for UI design.

MFC is mostly on maintenance and new application should use XAML + C++/CX.

C++/CX makes use of the C++/CLI extensions but it targets AOT compilation to native code instead.

The alternatives are C++ with WRL (Windows Runtime Library), basically ATL replacement, and what most Microsoft teams actually use for the UWP kernel components.

Because most C++ devs would rather use something more standards friendly, there is work in progress to eventually replace C++/CX with C++/WinRT, taking advantage of C++17 features.

Thanks this is great information. Have you looked into using Scala or Rust for UWP apps?

Not much, throughout my career I have learned that the best path is always to only use the officially supported SDK languages for production code.

All productivity or enjoyment using alternative languages gets lost in extra FFI layer, unavailable platform documentation, lack of support on the IDEs, poorer debugging, GUI tooling and code generation.

So I only use alternative languages to learn about new concepts and ways to improve my skillset, but in what concerns production code, the golden rule is 100% SDK languages.

Going back to your question, Java on UWP is only possible via the JVM provided by CodenameOne and I think it actually makes use of the Desktop Bridge, so that rules out Scala.

Rust still has a lot to catch up with C++ for using COM in a productive way, let alone .NET based languages.

UWP is basically what .NET should have been, if they had kept the original COM+ plans instead of going with the CLR. So any language targeting UWP needs to have seamless COM support, and ability to handle .NET metadata.
