Okta SSO integration using SAML in .net web application


i am working on okta SSO integration using SAML request and SAML response to authenticate .Net web based application(not supporting MVC) by referring following URL:


.NET Framework 4.5 or above: Kentor Authentication Services
  1. i registered at OKTA Organization for developer testing as per below URL guidelines


  1. when i try to download SampleApplication from following URL

and try to test Sampleapplication, here using ASP Identity principle which we do not support in our current project.

So here i need to have sample code blocks or what is better approach to test SAML Request and SAML Response to authenticate our web application( which is not supporting MVC).
