Description Sebastien Pouliot 2017-07-11 21:23:27 UTC
The current code for 

	interface WKHttpCookieStoreObserver
		[Export ("cookiesDidChangeInCookieStore:")]
		void CookiesDidChangeInCookieStore (WKHttpCookieStore cookieStore);

is incorrect since the native name is different. However using

	[Protocol (Name = "WKHTTPCookieStoreObserver")

result in build failures like

> error CS0246: The type or namespace name `IWKHttpCookieStoreObserver' could not be found. Are you missing an assembly reference?

It seems the file for the protocol type is not generated.

This is a pattern we've been using elsewhere but _maybe_ it's the first time without a `[Model]` ?

Weird, I remember using this elsewhere without a [Model], will test and report back
Comment 2 Alex Soto [MSFT] 2017-07-12 00:05:21 UTC
@Sebastien it works for me

[Mac (10,13), iOS (11,0)]
[Protocol (Name = "WKHTTPCookieStoreObserver")]
interface WKHttpCookieStoreObserver
    [Export ("cookiesDidChangeInCookieStore:")]
    void CookiesDidChangeInCookieStore (WKHttpCookieStore cookieStore);

Any chance you can double check again?
Comment 3 Alex Soto [MSFT] 2017-07-12 00:12:32 UTC
@sebastien I think I know what happened, you missed the closing bracket

> [Protocol (Name = "WKHTTPCookieStoreObserver")

This will result in just a warning

> wkwebkit.cs(129,2): warning CS0658: `interface' is invalid attribute target. All attributes in this attribute section will be ignored

and then you will get `CS0246` error `The type or namespace name `IWKHttpCookieStoreObserver' could not be found. Are you missing an assembly reference?` because the interface is missing the `[Protocol]` information.

Please let me know if it works for you :)
