Windows 7 Development Environment

Dec 11, 2009 at 3:26 AM

I need to set up a Development environment on Windows 7 64-bit.

I have tried everything but keep getting the same error


HTTP Error 500.19 - Internal Server Error

The requested page cannot be accessed because the related configuration data for the page is invalid.


Module IIS Web Core
Notification BeginRequest
Handler Not yet determined
Error Code 0x80070021
Config Error This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".
Config File \\?\C:\inetpub\wwwroot\blog\web.config


Any ideas?

I got the exact error message and it seems like i did not install the .NET components under IIS

I performed the following steps to fix the error

I enabled the following features under IIS 8 (Windows 8 Release Preview)

IIS > World Wide Web Services > Application Development Features > ASP.NET 3.5, 4.5, Extensibility, ISAPI.
