It is possible to load a whole process in Full Trust mode in a WinRT application adding this to its AppManifest:
<desktop:Extension Category="windows.fullTrustProcess" Executable="Win32Process_CPP.exe" />
While it works and I could potentially create a Service out of that, I would like to know if it is also possible to load a DLL in the same Full Trust manner.
e.g.,
<Extension Category="[something]">
<InProcessServer>
<Path>[MyWin32orCLR.dll]</Path>
<ActivatableClass ActivatableClassId="[Something]" ThreadingModel="both" />
</InProcessServer>
</Extension>
So I can call a function on MyWin32orCLR.dll with full trust access.
I know anything like this won't be publishable for the Windows Store but that is fine; I am trying to create a in-house App.
