Asp.net core 1 - authentication cookie not being set in Google chrome (works in IE)

See more:

MVC6

I'm using ASP.net Core 1, MVC 6. I am using SignInManager and UserManager, to authenticate a user in a web api application (MVC6 / C#) from another MVC application (the web api Logon method is actually called from a Jquery Ajax request).

In IE, I call the Login method and when successful, it gives me a Set-Cookie response with an ASP.net auth cookie. I can then see subsequent requests have the ASP.net auth cookie attached.

In chrome, the Set-Cookie directive is returned in the response, but subsequent requests do not have the cookie attached.

Why is this happening? The only difference I can see is that in Chrome, there is a pre-flight OPTIONS request being sent, but I have handled that in the startup.cs file in the web api and am essentially ignoring it.

What I have tried:

I'm not overly sure what to try to resolve this - I only see this behaviour in Chrome - works fine in IE.

Thanks for any help in advance!
