--- Comment #5 from Thomas Linder Puls thomas_linder_puls@hotmail.com --- dwrite_1.idl did not exist when I made the mentioned updates. I have not tried using it, but it includes dwrite.idl and I did not (in a quick glance) notice any name clashes.
Maybe someday I will also need _1 _2 and _3 and have to update them as well.
Anyway, it is not a big issue I have the updated file and I am probably also the only one that needs the update.
I just thought that this information could "flow " back to you. If nothing else then just to be a little closer to the "truth". I am sure Microsoft have a corresponding file with such annotations; they just don't publish it.
I asked them to publish similar information for the webView2 control, which they then included in the published file set. But that was while promotion of the control was in the early phases where there are still "real ears" to listen to your requests/suggestions/ideas. It is much more difficult to convince them about an ancient file (Sorry, that was a sidetrack :-)).
