IIS get full error message for failed requests

Question

I have IIS set-up and serving my webservice. Unfortunately if the webservice throws an exception, all I get is a blue box with the title failed request.

What options do I have to actually see what went wrong? I'd prefer to get the exception message and a stack trace.

I already set-up "Failed Request Tracing" but the directory remains empty. If possible I'd prefer to get the stack trace in the browser directly.

Just if this matters: I have an IIS 7.5 on a Win 7 64 Pro box. The Webservice is a WCF C# project.

Solution

You will find the errors in the eventlog, but having them in the browser is indeed more convenient (especially during development). To do that: turn on debugging in your web.config. Also, switch custom errors off or set them to "Remote only".

<configuration>
    <system.web>
        <customErrors mode="Off" />
        <compilation debug="true" />
    </system.web>
</configuration>

What is "Your.Service.Type"?

Mmmm... according to msdn.microsoft.com/en-us/library/dayb112d.aspx there's no <behavior> tag. Where should I put this?

It's in this path: <configuration> <system.serviceModel> <behaviors> <serviceBehaviors> <behavior> <serviceDebug includeExceptionDetailInFaults="true"/>

I managed to add this to the web.config. Unfortunately it breaks the service completely request to the webserver are not answered anymore.
