404 when running .net 4 WCF service on IIS (no svc file)

Question

I\'m testing out a REST service in WCF on .net 4 - i.e. no svc file. It works great when running against the VS dev server but when I switch it to run against IIS I get 40

Answer 1

I had runAllManagedModulesForAllRequests="true" in my web.config but still couldn't get past the 404.0. Also tried installing "IIS 7 Recommended Configuration" without any luck. Rerunning aspnet_regiis solved the problem to me.

1. In the Run dialog box, type cmd, and then click OK.

2. At the command prompt, use the cd command to change the directory of the Aspnet_regiis.exe version you want to use. By default, Aspnet_regiis.exe is located in the following directory: systemroot\Microsoft.NET\Framework\versionNumber

3. Then run the following command: aspnet_regiis -ir

This will register "svc-Integrated-4.0" in the Handler Mappings.
