body: <p>I'm using Nlog library for logging in my ASP.net website. I want to check whether log event should be logged or not in order to create a "StackFrame". according to Nlog documentation they have given "Check" method to do this. but it doesn't work for me. the Check method is not available. it would be really great if someone can help me on this.</p>
