Prevent ClickOnce publish in DEBUG mode

Any developer using ClickOnce has at least once forgot to switch to Release mode before a publish.

 

You are in a hurry to publish after a critical hotfix and forget to switch from Debug to Release mode in Visual Studio.

Prevent this with a simple BeforePublish script. Modify your project.cs file and put this at the end of the file before the </Project> end tag:

<Target Name="BeforePublish">
 <Error Condition="'$(DebugSymbols)' == 'true'" Text="You stupid. Publishing in DEBUG mode!" />
</Target>
