ASP.NET SessionState issue with UltimateSAML using EasySaml namespace

0
Hello, We ran into an issue using the UltimateSaml library. The code is not working when using sessionState mode="StateServer" (rather than InProc). The error is thrown when calling the method below: **Saml.IdentityProvider.InitiateSingleSignOn()** The exception is: **Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted.** It seems that the library puts an object in the Session object which is not marked as Serializable. We are currently evaluating your solution and this is a no-go for us. We can not change the sessionState to 'InProc' in our application. Is there any way to fix this issue? Thanks, Michel

Hello, We are fixing this issue in the example and a new build will be released today. Or you can comment out `Session[SsoAttrsSession] = attributes;` at line 50 in `Samples\Web\CS\Saml2-EasySamlApi\Saml2SsoDemo\ServiceProvider\AssertionConsumerService.aspx.cs`
