Web Forms and Core Authentication - asp.net

I have a .NET Web Forms website running in IIS (using forms authentication).
I've added a .NET Core 2.2 website as a sub application of the Web Forms site.
Is it possible to share authentication from the Web Forms site to the Core site?

I came across this: https://github.com/dazinator/AspNetCore.LegacyAuthCookieCompat
and was able to check for the forms auth cookie from the parent site when a requests hits the core sub application.
Then I could decrypt the forms auth cookie, to get the user info, and authenticate the user on the core site.
Not sure if this is ideal, because you know have to manage 2 cookies, but it seems to work.

Is there Sustainsys.Saml2 example for ASP.NET Web Forms

I try to SAML with Sustainsys.Saml2. I downloaded and run examples from their Github page. But all examples for ASP.NET MVC.
I develop my site with ASP.Net Web Forms. My site is service provider for SAML. I changed my web config as in the example but I can't redirect my login page to identity provider's login page.
The HttpModule sample is set up in the same way as a Web Forms app should be set up.

asp.net forms authentication across applications

I have a solution with an existing web forms website project (NOT web application project). I want to add a new mvc web application to the solution and have web forms site and mvc web app share forms authentication. I followed the article from microsoft but on localhost this does not work. In the solution, if I start both the webforms and mvc sites they have different port numbers for localhost so I authenticate in the webforms web site but the authentication cookie does not get picked up. Is there something obvious I am missing?

ASP.NET Forms and Windows Authentication for Different Domains

I have the following requirement: if a user in domain 2 goes into an ASP.NET site that is in domain 1, then the site should display a customised login form to validate the user. But if a user from domain 1 surfs to same the ASP.NET site (on domain 1), then Windows authentication (using Active Directory) takes place, so the user should goes straight through to the site content without seeing the login form.
How would I go about doing that?
Would I first need to detect the request domains? I have tried HttpContext.Current.Request in Page_Load() but have not yet been successful in detecting which domain a request is from.
Also, how should I setup the site authentication mode? Would I need Windows authentication for domain 1 users, and forms authentication for domain 2 users? I have also not been able to succeed in this, since IIS 7.5 complains that I cannot have both Windows and Forms authentication turned on.
Thanks.
Surely not an answer but due to the length, I am adding it as answer not comment.
AFAIK, IIS 7.5 allows both authentications to be enabled but no through web.config, you have to do it through IIS Management console, furthermore the scenario you described is handled through claims authentication (windows for intranet and forms for extranet) in Sharepoint 2010. I think same approach can be used in ASP.NET application since Sharepoint is also built on top of ASP.NET 3.5. More over you can look into Federated Authentication APIs present in .Net. You can explore the following links Claims Aware ASP.NET Applications and Federated Authentication and Enabling Federated Authentication for ASp.NET in Azure. Hope this helps.

Is it possible share authentication between Asp.NET web applications and silverlight business application

Is it possible share authentication between Asp.NET web applications and silverlight business application?
Scenario:
When uses logged in on either SL application or Asp.NET application using same browser, I want them to used active authentication. I have seen OpenId authentication can do such, But wondering can asp.net authentication is also able to do such.
Yes the authentication infrastructure can be shared between ASP.Net and SilverLight. If both the sites are under one domain, we can implement the standard authentication using ASP.Net Membership and role provider.
You can then use the WCF Authentication Service to and authorize user. This authentication is is good only for any server side functionality. If you want to authorize on client side (SilverLight) application you need to build your own infrastructure. Role and Membership provider data available can help you in that.
You can host your SL application in ASP.NET page and when somebody comes on this page do authentication. For instance, you can use FormAuthentication on the site, so when you are navigating from some page to page with Silverlight - access will be hovered by very FormAuthentication. OpenId you can use if ASP.NET app and Silverlight on different sites (domains), but if the Silverlight app is hosted on asp.net page you can also authenticate using asp.net infrastructure on server side.

Pass user credentials between SharePoint web application and ASP.NET web application

I need to integrate my sharepoint site and ASP.net site. So, First login will occur in the SharePoint site with Active Directory authentication and from there i need to traverse to ASP.Net site through a link. Now my question is whether its possible to pass my SharePoint Active Directory credentials to ASP.Net site? Will i be able to do this through a query string? Will i be able to navigate to and fro between SharePoint and ASP.Net sites.
The main point here is the user should not enter his credentials twice ( ie.. He should be authenticated automatically while navigating between two sites.)
What are the options available for me?
Do these things possible to achieve? SharePoint will be hosted using Windows SharePoint Services 3.0.
Thanks in advance,

Is the ASP.NET site on the same network? If so, then you can use AD (Windows Auth) for authentication on the ASP.NET site just like you're using it on the SharePoint site. You don't need to pass the credentials, and you can't anyway since all you have is an authenticated identity. If you configure the ASP.NET site to require Windows Authentication, you'll be able to get the user's identity from the server variables (AUTH_USER).
