I found that the token which is saved , it remains there after signing out as well.

I added option to save token from twitter

   twitterOptions.SaveTokens = true;

I Added one class to get the saved token

  public class UserTokenService
    {
        private readonly IHttpContextAccessor _httpContextAccessor;
        public UserTokenService(IHttpContextAccessor httpContextAccessor)
        {
            _httpContextAccessor = httpContextAccessor;
        }
        public async Task<string> GetToken()
        {
            var token = await _httpContextAccessor.HttpContext.GetTokenAsync("access_token");
            return token;
        }
    }

After signing out User.Identity.IsAuthenticated is false but token remains there.

I tried this in the cae of aspnet core mvc and it does clear token there.

They are still working on Authentication/Authorization in Blazor that I think affects the expected behavior related to 'sessions' . See: https://twitter.com/ADefWebserver/status/1122504410557554689

So after i log in with twitter the app crashes. Is this probably why?

In the latest Preview 4, using Visual 2019 preview version, it works on my desktop and laptop...

@kyledavi5 yes , connection to the server breaks, if so try to run this without debugging , it should works.As VS automatically open browser and after login to the twitter , it closes the twitter windows so it stops the Visual studio as well.
