I just updated all my identity nuget packages so that I can use
var result = await SignInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, shouldLockout: false);
but VS can't find it. It only finds SingInManager<> with intellisense. There is no SignInManager.PasswordSignInAsync(...). I even did a go to definition on SignInManager and looked at the source code in the library and it doesn't show a PasswordSignInAsync with any email parameter, jsut a username. I looked at the version at the top of the file and it shows
region Assembly Microsoft.AspNet.Identity.Owin.dll, v2.0.0.0
C:\TFS\GiftExchange\packages\Microsoft.AspNet.Identity.Owin.2.1.0\lib\net45\Microsoft.AspNet.Identity.Owin.dll
So I know I have the correct library right?

and even that seems to be broken. I'm trying to follow the code found here

I've updated all my nuget packages and checked them and they all are downloaded with their dependencies downloaded as well. Am I missing something to get SignInManager.PasswordSignInAsync?
