"interface not found" in WCF Moniker without registration for excel
- by tbischel
I'm trying to connect excel to a WCF service, but I can't seem to get even a trivial case to work... I get an Invalid Syntax error when I try and create the proxy in excel. I've attached the visual studio debugger to excel, and get that the real error is "interface not found". I know the service works because the test client created by visual studio is ok... so the problem is in the VBA moniker string.
I'm hoping to find one of two things:
1) a correction to my moniker string that will make this work, or
2) an existing sample project to download that has the source for both the host and client that does work.
Here is the code for my VBA client:
Dim addr As String
addr = "service:mexAddress=net.tcp://localhost:7891/Test/WcfService1/Service1/mex, "
addr = addr + "address=net.tcp://localhost:7891/Test/WcfService1/Service1/, "
addr = addr + "contract=IService1, contractNamespace=http://tempuri.org, "
addr = addr + "binding=NetTcpBinding_IService1, bindingNamespace=""http://tempuri.org"""
MsgBox (addr)
Dim service1 As Object
Set service1 = GetObject(addr)
MsgBox service1.Test(12)
I have the following service:
[ServiceContract]
public interface IService1
{
[OperationContract]
string GetData(int value);
}
public class Service1 : IService1
{
public string GetData(int value)
{
return string.Format("You entered: {0}", value);
}
}
It has the following config file:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.web>
<compilation debug="true" />
</system.web>
<!-- When deploying the service library project, the content of the config file must be added to the host's
app.config file. System.Configuration does not support config files for libraries. -->
<system.serviceModel>
<services>
<service behaviorConfiguration="WcfService1.Service1Behavior"
name="WcfService1.Service1">
<endpoint address="" binding="netTcpBinding" bindingConfiguration=""
contract="WcfService1.IService1">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexTcpBinding" bindingConfiguration=""
contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="net.tcp://localhost:7891/Test/WcfService1/Service1/" />
</baseAddresses>
</host>
</service>
</services>

</configuration>
