GeckoView Javadoc not working

[Daddoon]

The GeckoView JavaDoc seem to not working.
Even if files are generated, there is no match found for the generated C# API.

I don't know if it's Xamarin or GeckoView related.

Here some logs. Theses are maybe normal as they seem to not being documented in the original documentation:

How did you get this to compile (specifically the bindings project), I've tried everything even getting a new nightly build and it doesn't compile.

[Daddoon]

Actually, if you are talking about the current last buildable version (of GeckoView), things should works BUT there is a bug in Visual Studio 2019, and maybe your issue is related.

See this comment here: #1 (comment)

I checked my Xamarin.Android.Bindings.targets file, I don't have that entry from the comment you linked above. I'll keep digging, thank you. Where is Xamarin.Android.Bindings.targets located for you for VS 2019?
