The type 'ASP.global_asax' exists in both DLLs

When trying to compile .Net web project I encountered following error.

"The type 'ASP.global_asax' exists in both 'c:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\timesheet\15a75c54\898b48b9\assembly\dl3\58b062b2\00ceda54_c98cc801\App_global.asax.DLL' and 'c:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\timesheet\15a75c54\898b48b9\App_global.asax.q_h6dbfx.dll' c:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\timesheet\15a75c54\898b48b9\App_Web_admin.master.fdf7a39c.zecazgwd.0.cs "

When further troubleshooting in found that problem occurred in a virtual application's bin folder. Inside bin-folder there were two files.

App_global.asax.dll

App_global.asax.compiled

Removing these resolves the error for me.
