Compiler Error Message: BC30175: module 'ContextMenuHelpers' and module 'ContextMenuHelpers', declared in 'C:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\metroweb\87c204db\55321c07\App_Code.rcey62l6.13.vb', conflict in namespace '

This problem occurs because more than one file of the same class with the same namespace are found in the folder, usually App_Code folder. If you back-up the source files, make sure it is renamed as another extension, so that it does not conflict with the original file. Otherwise, either put your back-up files outside of the application, or archive it in a compressed file.
In the case I encountered, someone puts a back-up file in a new sub folder inside the App_Code folder. After renaming the extension of the back-up file, the problem is solved.
