I have a website that is running asp.net + mvc3 I have installed mvc 4 on my dev machine and since have removed it. since then I can't publish to my production server without getting this:
'error CS0433: The type 'System.Web.Mvc.WebViewPage' exists in both 'c:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\root\6c0d160f\330c4242\assembly\dl3\122e2e49\00f3d8c1_b3d8cf01\System.Web.Mvc.DLL' and 'c:\Windows\Microsoft.NET\assembly\GAC_MSIL\System.Web.Mvc\v4.0_188.8.131.52__31bf3856ad364e35\System.Web.Mvc.dll'
currently both machines have only asp.net mvc 3 installed. I have stopped the web server and deleted the temp files, didn't work.
any ideas? 10x Igal
