.net Exclude "Debug" code from Release dll (c#)

Question

Is it possible to exclude code that is marked as Debug exclude from Release ddl like:

#if DEBUG
Console.WriteLine("DEBUG");
#endif

#if RELEASE
Console.WriteLine("RELEASE");
#endif

if I build my solution as Release (with optimization) and open it via dotPeek I still see the same pies of code.

Is it possible to exclude code inside DEBUG directive?

UPD: I am trying to do it in an empty console application (.net 6).

There is my build command:

Commands starting with a # sign are called preprocessor directives and they control a thing called preprocessor, which runs on your code file before the compiler itself and allow you to modify the code that will be compiled.

Now, what the #if directive does is make code between those lines conditionally present in the code that gets compiled.

Take a look, this compiles fine:

using System;

#if NOT_DEFINED
I can type anything here because this won't get compiled at all.
#endif

Console.WriteLine("Hello, World!");

The thing about enclosing your own code between a #if DEBUG / #endif is that DEBUG is a preprocessor constant that is usually defined on Debug builds, and removed on RELEASE builds. There's nothing magical about this: you can see that you compiler command line has a /define: with the following constants:

/define:TRACE;RELEASE;NET;NET6_0;NETCOREAPP;NET5_0_OR_GREATER;NET6_0_OR_GREATER;NETCOREAPP1_0_OR_GREATER;NETCOREAPP1_1_OR_GREATER;NETCOREAPP2_0_OR_GREATER;NETCOREAPP2_1_OR_GREATER;NETCOREAPP2_2_OR_GREATER;NETCOREAPP3_0_OR_GREATER;NETCOREAPP3_1_OR_GREATER

I'm not familiar with Rider interface, but you can usually configure these constants using the project properties in Visual Studio (which you can find somewhere in Rider).

If you are really seeing the code that should have been excluded from build there, either Rider added the constant during compilation, or it's defined on csproj (based on your own answer, maybe asking to generate pdb files will also define the constant).

I have seen the full code because I build dll with pdb files. When I built just dll without pdb I got just release-related code. Look like my bad, because dotPeek automatically opens source code (actual Program.cs file) for me (not decompile dll if I build with pdb and symbols).

.net Exclude "Debug" code from Release dll (c#)
