關於錯誤 Compiler Error Message: CS0433: The type 'ASP.global_asax' exists in both 'c:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET
最近在移植一些專案遇到這個問題
Server Error in '/' Application.
Compilation Error
Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.
Compiler Error Message: CS0433: The type 'ASP.global_asax' exists in both 'c:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\root\64203716\99481ad\App_global.asax.lldgsdpc.dll' and 'c:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\root\64203716\99481ad\assembly\dl3\1fdcbdce\1ebebc9e_08a0d901\App_global.asax.DLL'
真的卡了一下，畢竟很少遇到，後來才發現在 bin 資料夾中 多了一些東西
App_global.asax.compiled ，App_global.asax.dll 
後來經過查詢原來是我在發佈得時候手賤勾選了 "在發佈期間先行編譯"
這個不要勾選，之後編譯出來就不會有了，接下來把機器上面的 bin 那兩個檔案 App_global.asax.compiled ，App_global.asax.dll 刪掉就沒事了
害我花了一點時間找問題，因為第一次碰到
