Yes. We are very keen on supporting WinRT with native Delphi & C++ code. Right now, the issues surrounding the WinRT space center around the fact that many
OS-supplied APIs which are required by anyone implementing their own language
RTL are actually off-limits unless
you're the VC++
RTL DLL.
...
We're currently rattling some cages at MS to find out how or if they're going to allow third-party tools to target WinRT.
...
We are able to build WinRT applications with Delphi that work with a developer certificate, however they all fail the application qualification checks because of the aforementioned (an other) APIs.
...
Like the APIs I mentioned above, there are lots of changes with WinRT that make targeting it a little more tricky. For instance, you cannot merely open any file,
access the registry, and even use the loopback (127.0.0.1) adaptor. LoadLibrary cannot be used to load any arbitrary
DLL; you must call LoadPackageLibrary and only on a
DLL that is present
in the digitally signed appx
package. WinRT is a seriously locked down sandbox or "walled-garden" with some extremely high walls.
