To confirm, was this issue with the metadata?

[Tanya-Solyanik]

@Epica3055 - this is the minimal test. Could you please add more coverage?

@Tanya-Solyanik Yeah sure.
I think there are three methods should be tested.
But not all of them involve using native dll. This one I wrote here definitely involves using that ( I ran this test before and after the PR ). So I guess maybe this one is enough?

[Epica3055]

for example when I write one like this

    [Fact]
    public void ShowHelpTest()
    {
        Help.ShowHelp(null, "https://www.microsoft.com/");
    }

it doesn't involve using native dll.

[Tanya-Solyanik]

I see, you are right, for this issue, one is enough. However we need code coverage for all methods on this control eventually. I thought that once you are working in this space, it's easy to add more tests.

[Epica3055]

This Help is like a general method, not for a specific Control.

I guess this issue can track all Control tests.

Yes, metadata is already fixed, thanks to Lachlan, do we know how much time it would take to update metadata and Win32?

[elachlan]

Can happen in a day or so depending on the teams.

If the new metadata is not published by the middle of the next week, we'll merge this PR and re-open #9884
