visual studio 2010 - Why does Debug.Writeline stop working for some projects in the solution?

Question

We have a solution with multiple projects after running the code from VS the output normally seen from Debug.Writeline statements just cease to appear. I mention the multiple projects because the output from one of the projects continues to appear. However, the other project consistently stops showing the output from the statements.

It's starting to drive me crazy. I should mention this is also occurring for a second developer on the project. Anyone seen this before, or have any ideas?

Answer 1

Follow these steps, it works for me

1. Right click on your project
2. Select Properties
3. Select tab Build
4. Make sure Define DEBUG constant is checked

Hope that helps
