IIS 7 not recognizing svc file

Question

I'm trying to publish a webservice using WCF on IIS7.

I've created a Site for this project, and I created an Application too as MSDN suggested. I can open html files in my browser from the created folder, but I get 404.3 error (The page you are requesting cannot be served because of the extension configuration) if I try to access the svc file of my service. I've read that I should run servicemodelreg to install the missing handlers for the svc files. After I did I got an error saying that the handler has a bad module.

I checked the following stuff every time:

• IIS is turned on
• ASP.NET is turned on
• There is a handler for the svc files

I ran out of ideas...

Answer 1

On windows 8, run DISM.exe in order to enable WCF:

DISM /Online /Enable-Feature /FeatureName:WCF-HTTP-Activation
DISM /Online /Enable-Feature /FeatureName:WCF-HTTP-Activation45

Or if you are setting up everything using Server manager Dashboard's Add Roles and Features Wizard do not forget to check "HTTP Activation" under WCF Services

Answer 2

It happens if IIS is installed after .NET Framework and Visual Studio, so it is necessary to register ASP.Net. If to install IIS at first, there will be no such problems.

But the solution is simple: open Visual Studio Command Promt and type this command

aspnet_regiis.exe -i

Here is a link with more detailed information about this command and its parameters.
