CS0433: 'ASP.global_asax' 에러

"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 "

Setting "batch=false" into web.config's is not working. I have also tried to delete all folders from "c:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\", then clean and rebuild soultion. But still it's not working.

이런식으로 떳었다.... 구글링해서 찾아보니

In my case the problem occurred in a virtual application's bin folder. Looking into this bin-folder you will probably see two files (an information I found here):

• App_global.asax.dll
• App_global.asax.compiled

Removing these resolves the error. The App_global.asax.dll is generated at runtime too which causes the problem. I am however still investigating how these files got there, so comments are definitely welcome!

/bin폴더 안에 아래 두개의 파일을 삭제하여 주니 해결 되었다...ㅋㅋ

• App_global.asax.dll
• App_global.asax.compiled
