Yes, you are right, I think localhost is sharing cookies (.aspnetcore.identity.application), When I open another browser, the problem does not occur. This is also an undesirable situation. Is there a way to solve this for us? Can we set a cookie for the application?
The problem with my SSO MVC example still persists. I sent the sample project to liming.ma@volosoft.com via wetransfer.
Another problem is as follows; I open two different empty applications (MVC UI) and run them without changing any settings. I cannot log in to both at the same time. When I log in to one, the session in the other application is terminated.
