Unwanted Data Dump to Screen in Localhost

问题

I'm guessing if you've seen something like this before, you know what it is.

Personally, I don't know where to start with describing this issue other than it looks like all of my standard output is somehow going to the console.

From what I can tell, this stuff is not called in my code, but then I generally work with Windows Forms, not ASP.NET.

That's because you have Trace enabled on either the web.config or at the page level.

 <system.web>

  </system.web>

Or:

<%@ Page Title="Home Page" Trace="true" Language="C#" AutoEventWireup="true"
    CodeFile="Default.aspx.cs" Inherits="_Default" %>
