Hi neveroffline,
>Is VAST not supported on anything but the JS version of the ADs SDK?
Showing Ads in video content is currently supported only for UWP apps that are written using JavaScript with HTML. You could see more details in document:
Show Ads in video content
>Is there a way to parse the VAST and get it to work with the C# version of the mediaplayerelement?
There may be no common method for this, could you submit a feedback at
Uservoice site so that MSFT might will add it to their to-do-list based on your idea?
Best regards
