Problem Hosting WCF on IIS

Hope someone can help me with this.

I have installed Windows SDK Vista (6.0.5472.2.1) on my XP pro machine and I
try to run a small test service. This works fine when it is self hosted (by
console app) but I get a strange error when trying to host is on IIS (5.1).




Error msg (Shortened):
[ArgumentException: This collection already contains an address with scheme
http. There can be at most one address per scheme in this collection.
Parameter name: item]
System.ServiceModel.UriSchemeKeyedCollection.InsertItem(Int32 index, Uri
item) +2316953 ..........

[ServiceActivationException: The service '/hello/HelloWorld.svc' cannot be
activated due to an exception during compilation. The exception message is:
This collection already contains an address with scheme http. There can be
at most one address per scheme in this collection.
Parameter name: item.]
System.ServiceModel.HostingManager.EnsureServiceAvailable(String
normalizedVirtualPath) +962

System.ServiceModel.ServiceHostingEnvironment.EnsureServiceAvailableFast(String relativeVirtualPath) +419 ..........

Magnus,

Could you post your web.config file and your .svc file? It sounds like the
service is being configured incorrectly.

It sounds like you might have specified several base addresses with the
same protocol? Correct me if I'm wrong, but if you for instance have
three HTTP endpoints, you should only specify one base address, such as
http://localhost/MyService.

So in the web.config/app.config file:

<host>
<baseAddress>
<add baseAddress="http://localhost/MyService" />
</baseAddress>
</host>

The config file settings assume you are running at least the June CTP
(I believe) of the .NET Framework 3.0. Otherwise, you will have to
specify these addresses in code.
