My project is a web service project. I have been working on it for weeks and everything has been fine. For some unknown reason I started getting the error:You are debugging a release build of "my project.dll". The build is in debug mode. To the best of my knowledge, I didn't change any settings. It just stopped working.
I researched this and found numerous posts but none of the solutions has worked for me. I have cleaned, rebuilt, restarted IIS, rebooted, upgraded visual studio, etc, etc, etc. Nothing has worked.
I have had similar errors on different projects before, and the Clean usually fixes, but not this time.
How do I fix this? I will never get the 1/2 day wasted back!

Use the Configuration Manager to check what the actual settings are for the Debug configuration - it's at Build\Configuration Manager in the main menu - in case they are set to use Release:
Also, make sure the project is defining DEBUG correctly, and that "Optimize Code" is not checked:

I checked bot of these things (multiple times). They are set correctly. I have tries everything anyone ever suggested related to this issue. I can;t get around it. Today, I installed Visual Studio 2017 Preview. It did the same thing. The only thing I can think of is to create a new empty project, and add my code to it. It seems there is something in the project causing things not to work. That might work, but it seems like a serious problem to me if I can't debug my code.

Please update to 15.5.5 which is the newest one at present.
Also, please disable this option under Debug->Options->Suppress JIT optimization on module load (Managed only), And turn off the “Enable Just My Code” in the Debugging General Options and see.
**>>The only thing I can think of is to create a new empty project, and add my code to it. It seems there is something in the project causing things not to work. **
Does it mean it run fine in the new project? If so, it's more related to the code in the project other than VS IDE issues, right?

This isn't a solution. It's just hiding the message. The issue isn't solved by just hiding the warning message, I'm afraid.
