title: How to upgrade Sustainsys.Saml2 from version 0.23.0 to version 2.0.0
body: <p>I want to upgrade Sustainsys.Saml2 Nuget package from version 0.23.0 to version 2.0.0.<br/>
  I have an error in next line of code: spOptions.SystemIdentityModelIdentityConfiguration.AudienceRestriction.AudienceMode = AudienceUriMode.Never;.
  The SPOptions class doesn't have a IdentityConfiguration property anymore.</p>
  
  <p>var spOptions = new SPOptions();</p>
  
  <p>spOptions.SystemIdentityModelIdentityConfiguration.AudienceRestriction.AudienceMode = AudienceUriMode.Never;</p>
  
  <p>I want to know how to receive the same behaviour after updating to version 2.0.</p>
