Fixing common issues when hosting a .NET 4.0 WCF service in IIS 7

Until today I never had to host a WCF service in IIS… I always prefered using a ServiceHost in a Windows Service. Before getting my service up and running I had to face some issues.

Could not load file or assembly ‘service’ or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.

The problem here is that I’m running a .NET 4.0 service in a .NET 2.0 IIS and AppPool. I had to make the following changes:

• Change the IIS .NET Framework version to v4.0.30319 (click on the machine name in IIS Manager and in the right pane choose Change .NET Framework Version)
• Change the .NET Framework version of the AppPool too v4.0 (via Application Pools) or create a new Application Pool.

The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map. Detailed Error InformationModule StaticFileModule.

The reason for this issue: the ServiceModel for .NET 4.0 was not installed. Run ServiceModelReg.exe -ia to solve this. 
Depending on your machine and the .NET version you are running the file could be in one of the following locations:

• C:\Windows\Microsoft.NET\Framework\v4.0.30319\
• C:\Windows\Microsoft.NET\Framework64\v4.0.30319\

Handler "svc-Integrated" has a bad module "ManagedPipelineHandler" in its module list

1. This means that ASP.NET 4.0 was not installed (correctly). Run aspnet_regiis.exe -i using Visual Studio Command Prompt (2010) or via "C:\Windows\Microsoft.NET\Framework\v4.0.30319".
2. I also had to install the WCF Activation feature under .NET Framework 3.5.1 Features
