Azure Functions Support .Net Core

[digitalgym]

When trying to evaluate a script in an Azure Function app using Core 2.0 I get the following exception. I have tried installing Emit, no effect.

System.MissingMethodException: 'Method not found: 'System.Reflection.Emit.AssemblyBuilder System.AppDomain.DefineDynamicAssembly(System.Reflection.AssemblyName, System.Reflection.Emit.AssemblyBuilderAccess)'.'
