NullReferenceException in RegisterLicense on Xamarin.iOS

[rbakhshi]

After upgrading to 3.0.15 our iOS app crashed with following stack trace:

System.NullReferenceException: Object reference not set to an instance of an object
   at Newtonsoft.Json.Schema.Infrastructure.Licensing.LicenseHelpers.RegisterLicense(string license)
   at Newtonsoft.Json.Schema.License.RegisterLicense(string license)
   at Company.App.SetupLicenses()

Please note: the actual license string is not null or empty. The code in SetupLicenses verifies that before calling RegisterLicense.

Looking at the code I suspect something to do with reflection related code when trying to get the Assembly or Attribute on iOS.

Please note on iOS the production Xamarin app runs with JIT-ed .NET code and assemblies stripped down to only declarations.

Downgrading to 3.0.14 solved the issue for now.

I'm not sure what could cause that error. This is the difference in changes that happened between 3.0.14 and 3.0.15: 3.0.14...3.0.15

There were no changes to the License or LicenseHelpers types.
