Logging Internal Classes

Logging Internal Classes

So far, all of our examples have been with public classes and interfaces. You may want to keep your classes and interfaces internal like this:

abstract class CalculatorEventSource : EventSource
{
	public abstract void Clear();

	public static CalculatorEventSource Log = EventSourceImplementer.GetEventSourceAs<CalculatorEventSource>();
}

If you do this, you will get the following error:

Unhandled Exception: System.TypeLoadException: Type 'CalculatorEventSource_Implemented' from assembly 'EventSourceImplementation, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is attempting to implement an inaccessible interface.

That's because ESP doesn't have access to your class. You can fix this with an assembly attribute. Add this to your AssemblyInfo.cs file:

[assembly: InternalsVisibleTo("EventSourceImplementation")]
