Hello you guys. I have a project long time to develop with Asp.Net  MVC Framework version 4.5. It still works fine but today I run and got an error DirectoryNotFoundException: Could not find a part of the path '..\bin\roslyn\csc.exe'.

[DirectoryNotFoundException: Could not find a part of the path 'E:\Project\Philip\Main\Source_New\Admin\Source\admin\DVG.APA.CMSApi\bin\roslyn\csc.exe'.]

What's that mean? Anybody can explain it to me?

I tried to clear and rebuild much time but it still does not work for me.

Thanks for any suggestions.
