I have used forms authentication across different sites already, even between different versions of .NET, but now we're looking into starting a new project in ASP.NET 5 (MVC 6) ASP.NET Core and would like to use cookie-based forms authentication across both. The login is done in "old" MVC 5 application.
Is some cross-applications configuration for cookie-based forms authentication even possible or supported with current version of ASP.NET 5?
Could this be implemented on MVC6 ASP.NET Core side using FormsAuthenticationModule or can it play along somehow with the new authentication middleware? Any other suggestions?
WebForms is not a part of ASP.NET 5. This is change #2 according to this blog postUpdated
The new lifecycle of ASP.NET MVC 6 uses a middleware to compose services. You can use Security package to authenticate, but the old "Forms" authentication is not supported anymore.
