WCF Config in Asp.net web site

Hi

I am trying to get a WCF service running in an ASP.Net project (will run in IIS 7 but I can't get it work in visual studio for the moment). The reason why I need WCF is because I want to use MTOM encoding which is not available in a classic asp.net webservice. For the same reason I want to configure it so that I can upload large binary messages.

That means that I do need to specify the configuration of the service in web.config.

the service is located in a file called "albumservice.svc" in the root of the website, and the corresponding interface (Ialbumservice) is correctly implemented (albumservice class).

You can find below the web.config file I currently have. With this I am getting the following error when trying to view the service in a browser (the rest of the site works corretly):

Could not find a base address that matches scheme https for the endpoint with binding albumWSbinding. Registered base address schemes are [http].
[InvalidOperationException: Could not find a base address that matches scheme https for the endpoint with binding albumWSbinding. Registered base address schemes are [http].]
   System.ServiceModel.ServiceHostBase.MakeAbsoluteUri(Uri relativeOrAbsoluteUri, Binding binding, UriSchemeKeyedCollection baseAddresses) +12230836
   System.ServiceModel.Description.ConfigLoader.LoadServiceDescription(ServiceHostBase host, ServiceDescription description, ServiceElement serviceElement, Action`1 addBaseAddress) +12228189
   System.ServiceModel.ServiceHostBase.LoadConfigurationSectionInternal(ConfigLoader configLoader, ServiceDescription description, ServiceElement serviceSection) +67

I keep looking around but it doesn't look like I am doing anything wrong. Removing the address tag of the endpoint doesn't help. If anyone has any suggestions, they are more than welcome!

thanks
Charles

Check this out.  This might help:

http://www.codewrecks.com/blog/index.php/2009/11/25/wcf-over-secure-transport/

http://www.codeproject.com/KB/WCF/WCF.aspx

You might need to use mexHttpsBinding rather than mexHttpBinding

and you might need to do this <serviceMetadata httpsGetEnabled="true"/> rather than <serviceMetadata httpGetEnabled="true"/>

But that's what I don't understand. I am not using https. I am trying to consume this service over regular http.

What is your base address anyway?  Did you set this up programmatically or within config?  Your base Address might be based on https.

something like this under services --> service tag.

   <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8081/test/" />
          </baseAddresses>
        </host>

my understanding was that if the service is hosted in IIS I should not need to specify the base address. Which would force me to hardcode in config some development specific variable.

actually asp won't even let me do it:

Error message
When 'system.serviceModel/serviceHostingEnvironment/multipleSiteBindingsEnabled' is set to true in configuration, the endpoints are required to specify a relative address. If you are specifying a relative listen URI on the endpoint, then the address can be absolute.

Oh yeah.  You generated a web site project (IIS Hosting) for the WCF service library.  Sorry, I was thinking of something else.

OK.  Your IIS website is based on http, right?  What is the address?  Is it something like "http://localhost/sample/albumservice.svc"?

And changing mexHttpBinding to mexHttpsBinding doesn't affect the error

and what is weird is that I I add a new WCF service to the project (but don't alter anything to the web.config) this new service works. Obviously this is not good enough for me as I need that service to use a different encoding and max request size than the values by default. But it doesn't seem to be anything else than something wrong in my web.config

Just checking.  In my case, it is always http.  It should be http in development anyway.  :-)

That is just weird.  Anyway, I'll come back to this later.  I'm going to a meeting now. :-)

OK.  This might be an IIS configuration issue.  Check the link below:

I hope this helps.

You did it!
removing the security part from the binding solved the problem! Would have never found that myself!

Thanks for your help!
