I am trying to create a simple ConsoleApplication in which i would like to host a simple wcf service.
Here is the code for my
namespace HostConsoleApplication
{
class Program
{
static void Main(string[] args)
{
using (System.ServiceModel.ServiceHost host = new System.ServiceModel.ServiceHost(typeof(FirstWcfService.Service)))
{
host.Open();
Console.WriteLine("Sai");
Console.ReadLine();
}
}
}
}
Then i have added an app.config which looks like this:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<services>
<service name="FirstWcfService.Service" behaviorConfiguration="ServiceBehavior">
<endpoint address="FirstWcfService" binding="netTcpBinding" contract="FirstWcfService.IService"/>
<endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="mex" />
<host>
<baseAddresses>
<add baseAddress="net.tcp://localhost:9101/"/>
</baseAddresses>
</host>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="ServiceBehavior" >
<serviceMetadata httpGetEnabled="false" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>
When i run the host console app i get this exception:
System.InvalidOperationException was
unhandled Message="Could not find a
base address that matches scheme http
for the endpoint with binding
MetadataExchangeHttpBinding.
Registered base address schemes are
[net.tcp]."

Just wondering if how to fix this.

Well, I think the problem is this:
Basically if you want to use MEX over http, you need to supply either a full address for the MEX endpoint, or a http base address (if you only specify a relative address).
Solution 1: specify a full address for the MEX endpoint:
Solution 2: define an HTTP base address, too:
Solution 3: use the mexTcpBinding instead
Any of those three options should should solve it.
A word of caution: I find it quite risky to call your service behavior configuration "ServiceBehavior"......
My recommendation: call your first and default configuation just plain "Default" (or "DefaultBehavior")
and only start giving out other names if you have multiple configurations.
Calling this
ServiceBehavior
just seems to be asking for trouble some time later on.....
