WCF 405 에러 발생시 대처방법

Normally, 405 error code is because two reasons;

1) ASP.NET is not installed or register to your IIS

2) The *.svc file type is not mapped to the aspnet_isapi.dll

to solve problem:

1. register ASP.NET runtime from VS.NET 2005/2008 command line run: aspnet_regiis –i –enable

2. map *.svc file by

2.1 Win2003 or XP run: "%WINDIR%\Microsoft.Net\Framework\v3.0\Windows Communication Foundation\ServiceModelReg.exe" -r

2.2 Win2008 or Vista run: "%WINDIR%\Microsoft.Net\Framework\v3.0\Windows Communication Foundation\ServiceModelReg.exe" -L

3. then restart your IIS  iisreset /noforce
