Instance of advice attribute is created twice.

Hi again 😃

Another issue from my side.

I’ve updated my project to use MrAdvice from v.2.0.16 to v2.8.5 and noticed strange thing - the actual advice attribute instance is created twice. To check this behavior just put some output log into advice attribute ctor and You’ll see this log twice. I declare advice this way:

[AttributeUsage(AttributeTargets.Method, AllowMultiple = true, Inherited = false)]
public class AdviceAsyncAttribute : Attribute, IMethodAsyncAdvice
{
	public AdviceAsyncAttribute()
	{
		Console.WriteLine("ctor AdviceAsyncAttribute");
	}

	public async Task Advise(MethodAsyncAdviceContext context)
	{
		Console.WriteLine("Before MethodAsync");
		await context.ProceedAsync();
		Console.WriteLine("After MethodAsync");
	}
}

This behavior is on Windows with .NET Framework.

Yes, there is no guarantee an attribute is created once (or twice). So if you want to store extra data related to instances, you can use introduced fields, they’re designed for it. More details at https://github.com/ArxOne/MrAdvice/wiki/IntroducingFields

Sure, I’ll provide my example a little bit later 😃
