Where will Debug.WriteLine in C# output to when build release?

I put a lot of Debug.WriteLine in my code for debug purposes. When I am ready to build for release, will these Debug.Write influence the release build, and where do they output to?

From MSDN: "The ConditionalAttribute attribute is applied to the methods of Debug. Compilers that support ConditionalAttribute ignore calls to these methods unless "DEBUG" is defined as a conditional compilation symbol. Refer to a compiler's documentation to determine whether ConditionalAttribute is supported and the syntax for defining a conditional compilation symbol."

So if your release configuration does not include DEBUG symbol the Debug.WriteLine calls will be omitted during compilation and there will be no output.

If you switch them to Trace.WriteLine you can define arbitrary listeners in the app/web.config file.

Debug.Writeline is not compiled into release code.

Debug.WriteLine is annotated with the Conditional attribute. (see MSDN)

The ConditionalAttribute tells the compiler not to generate that code unless the DEBUG flag is supplied.

I believe it will be compiled out.
