How can I see console output from inside WCF service while debugging?

Question

How might I see the SQL query generated from LINQ to SQL when debugging inside a WCF service? I thought I might just set dataContext.Log = Console.Out and the SQL would be written to the output/immediate window. It doesn't--is that because I am hosting using IIS? Console.WriteLine("Hello") doesn't even write anything to the output/immediate window.

How do see my console output?

You can try to use System.Diagnostics.Debug.WriteLine(), so when you distribute Release app these lines will be stripped out from code.

Debug.WriteLine outputs to the Immediate Window, but Console.WriteLine doesn't. What's up with that? Unfortunately, there's no Debug.Out TextWriter that I can pass in to dataContext.Log. – Patrick Szalapski May 25 '11 at 21:26
WCF service hosted on IIS do not have access to Console. – YetAnotherUser May 25 '11 at 21:28
Oh really? Is there any TextWriter that will write to the same place as Debug.Write? – Patrick Szalapski May 25 '11 at 21:33

You may want to write it to a file instead. dataContext.Log takes any TextWriter.

See this comment for a nice way to get a text writer writing to Debug.

Yep, writing my own TextWriter worked. Not the best solution I might imagine, but it worked. – Patrick Szalapski May 25 '11 at 21:39
