That last step...

[PunkStarStudios]

I have that last step as being this : using (var myStream = new MemoryStream()) { PassWriter.WriteToStream(myPass, myStream, new X509Certificate2("MyFiles/AppleWWDRCA.cer"), new X509Certificate2("MyFiles/Certificates.p12", "mypassword"));

        }

But I am getting two exceptions :

System.TypeInitializationException HResult=0x80131534 Message=The type initializer for 'ServiceStack.Text.JsConfig' threw an exception. Source=ServiceStack.Text StackTrace: at ServiceStack.Text.JsConfig.CreateScope(String config, JsConfigScope scope) at PassSharp.PassWriter.ToJson(Pass pass) at PassSharp.PassWriter.WriteToStream(Pass pass, Stream stream, X509Certificate2 appleCert, X509Certificate2 passCert) at PasskitServer.Controllers.PassesController.Get(String PassTypeId, String LoyGUID) in C:\Users\punky\Documents\Visual Studio 2017\Projects\PasskitServer\PasskitServer\Controllers\PassesController1.cs:line 74 at Microsoft.AspNetCore.Mvc.Internal.ControllerActionInvoker.<InvokeActionMethodAsync>d__12.MoveNext()

Inner Exception 1: TypeInitializationException: The type initializer for 'ServiceStack.LicenseUtils' threw an exception.

Inner Exception 2: FileNotFoundException: Could not load file or assembly 'System.Configuration.ConfigurationManager, Version=0.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'. The system cannot find the file specified.

Can someone point out what I am doing wrong?
