Hi All,
As I understand, in order to configure a WCFservice endpoint to be interoperable with ASP.NET Web service clients, I must use the BasicHttpBinding type as the binding type for my service endpoint.
but why isn't it possible to add additional endpoints like wsHttpBinding, TcpBinding... (in addition to BasicHttpBinding) ?
Its important for me to expose all types of bindings .
It is possible to add other endpoints.
The issue is that if you add non-interoperable endpoints then your WSDL get 'polluted' whith metadata that cannot be understood by other toolkits - and thus their respective code generation APIs/tools break.
So if you want to expose several endpoint then disable them temporarily and let 'the others' generate code or - better! - give them just the static WSDL.
Hi,
Thanks for the reply.
what do you mean by "static WSDL"?
I tried to add additional endpoints , but I failed to start the com+ components (via the "Components Services").
(my wcf wervice is hosted in complus) .
when I set GetHttpEnabled = "true" only one http endpoint works. (basicHttpBinding or wsHttpBinding)....
Any exceptions? Event log? Did you enable tracing for the WCF service to see more details?
BTW: why exactly do you want to host in COM+?
Hi,
Thanks for your reply.
I get the exception from windows "Component Services" when right clicking on a com+ application and clicking "start".
"Error Code 80080005 - Server Execution Failed"
in the Event Viewer I get the following message :
The initialization of the COM+ surrogate failed -- the CApplication object failed to initialize.{89C8E3CC-0C46-4B1E-BE46-EF1E58153E09}

The serious nature of this error has caused the process to terminate.
Error Code = 0x80131509 :
COM+ Services Internals Information:
File: d:\qxp_slp\com\com1x\src\comsvcs\srgtapi\csrgtserv.cpp, Line: 363
Comsvcs.dll file version: ENU 2001.12.4414.310 shp
in the trace :
A binding instance has already been associated to listen URI 'http://localhost:8080/ComTest/COMTest.clsCOMTest/_clsCOMTest'. If two endpoints want to share the same ListenUri, they must also share the same binding object instance. The two conflicting endpoints were either specified in AddServiceEndpoint() calls, in a config file, or a combination of AddServiceEndpoint() and config.
I decided to host my wcf service in COM+ because I already have all the interfaces i need in an existing dll , so I use comsvcconfig to install all the contracts. (in that way I can expose my dll as a wcf services).
I guess the exception says it all: you two same endpoint URLs. Either you make them unique or you set a unique ListenUri.
Can you show your endpoint config please?
here is the application.config:

configuration>what is the ListenURI?
before I added to the service behaviour GetHttpEnabled = "true" (in order to consume the wcf service from a web page).
I was able to add any endpoind I wanted (tcp, basic http, ws http...)
Thanks
Can you please try using these endpoints?
I.e. unique endpoint addresses.
