Not sure why this is failing ...

Tried:

Implementing Ninject.Extensions.Interception.IInterceptor, easy enough called 'InstrumentationInterceptor'.

public class InstrumentationInterceptor : IInterceptor
	{
		private static readonly ILog Log;

		static InstrumentationInterceptor()
		{
			Log = new RepositoryLoggingService().GetLogger(typeof(InstrumentationInterceptor));
		}

		private T TimeWrap<T>(string message, Func<T> function)
		{
			var stopWatch = Stopwatch.StartNew();

			var result = function();

			stopWatch.Stop();

			Log.Info($"{message}::{stopWatch.ElapsedMilliseconds}ms");

			return result;
		}

		public void Intercept(IInvocation invocation)
		{
			var message = $"Connect.Repository.Instrumentation -> {MethodSignatureFormatter.GetSignature(invocation.Request.Method, invocation.Request.Arguments)}";

			TimeWrap(message, () =>
			{
				invocation.Proceed();

				return invocation.ReturnValue;
			});
		}
	}

Then registering with:

Kernel.Bind<InstrumentationInterceptor>().ToSelf().InSingletonScope();

 Kernel.Bind(x => x
                .From(GetType().Assembly)
                .SelectAllClasses()
                .InNamespaceOf(GetType())
                .BindAllInterfaces()
				.Configure(c => c.Intercept(
					typeof(InstrumentationInterceptor),
					typeof(DatabaseWinsConcurrencyInterceptor))));

Ended up with:

[NullReferenceException]: Object reference not set to an instance of an object.

Any idea's?

Closing this for now. Thanks.

You missed With function after Intercept

[scott-xu]

The syntax is "intercept some types with some interceptors"

@scott-xu - thanks, this really was not obvious.
