Support for Windows Store App projects that generate a .EXE or .DLL file is present and working in the current release as is support for .winmd files as reference assemblies.
Support for .winmd files as documentation sources was added on Oct 27 and the changes have been checked in. I haven't published a new release containing those changes but probably will within the next couple of weeks. A number of other significant
changes have also been made that I'm in the process of documenting. If you choose to download and build the code, I can't realistically provide support for it yet as I haven't finalized and tested all of the changes. I'm in the process of doing
The workaround for the time being is to make a copy of the .winmd file with a .dll extension. As noted in the check-in notes, I'm not sure if this was worthwhile as a majority of the user written code in the assembly is marked as compiler generated
and thus does not show up in the help file, at least that's what happened in the test project I created but it was just a Hello World type of thing just to use for a test. I may need an option to include compiler generated code. We'll see how it's used.
A proper project with actual code would also be of help in that case too.
