The IIS config may be locked if ASP.NET 4 is not installed

[Tratcher]

The Asp.Net 4.5 installer unlocks IIS’s system.webServer/handlers section. However if you don’t install that component then the section remains locked and you can’t enable HttpPlatformHandler. Should the HttPlatformHandler msi unlock that section?

Yes it should

handlers section is never locked - whats the machine configuration?

[Tratcher]

As far as I know it's locked for any default windows install if you do not also install ASP.NET 4. Several people have reported this recently: aspnet/Hosting#364 (comment)

Actual error message: "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"."

This as been fixed in AspNetCoreModule v0.8: #105.
