I have a .net application which is using very old version of .net which is .net core 1.1. We have a requirement to integrate SAML2 identity provider in our organization. We can't upgrade this application to newer .net version for some reasons.
I have read your github documentation where it is mentioned to use minimum .net core 3.1. My Question is that Is there any kind of possibility or hack where I can use ITfoxtec.Identity.Saml2 package in my application which is having older .net version.
It is not possible to use .NET Core 1.1 without also using the full .NET Framework. Which is a bad idea and probably not possible either.
I think the best solution is to use a broker to transfer from SAML 2.0 to OpenID Connect. Then you need to implement OpenID Connect in your applications, which is possible in .NET Core 1.1.
