If you see any problem with NET TCP Service, You can use following config to debug NET TCP problems

On 64 bit machines, you have to add this info to C:\WINDOWS\Microsoft.NET\Framework64\v3.0\Windows Communication Foundation\SMSvcHost.exe.config

On 32 bit machines, you have to add this info to C:\WINDOWS\Microsoft.NET\Framework\v3.0\Windows Communication Foundation\SMSvcHost.exe.config

WSE3 -> WCF INTEROP BASICS

madhu_ponduru@hotmail.com — Sun, 04 Jun 2006 20:05:00 GMT

How to send Message from WSE3 client to WCF service?

WCF SERVICE SIDE:

(1)You have to define custom binding to communicate with WSE3 client apps(when you are communicating with WSE clients, you can't use standard binding)

(2) In this custom binding, you have to use 2004 ws-addressing (Soap11WSAddressingAugust2004)

(3) Creating custom binding is not tough, what we are doing in this custom binding is

we are going to use Http transport
we are going to use 2004 ws-addressing (WCF will use recent soap ws-addressing spec, This is not compatible with WSE3 ws-addressing,so we have to tell to WCF service to use 2004 ws-addressing spec)
Most important thing is, what would be WCF service security policy (Policy defines security requirements for your service)

Please check SAMPLE1 and SAMPLE2 WCF service custom binding to know,How we defined custom binding

WSE3 CLIENT SIDE:

Add WSE support for client project(you can enable this by WSE3 config tool)
Generate proxy code by using Add web reference wizard
create security policy for WSE client app by using wse config tool and include this policy in client project (when you are creating the security policy, check what is your security policy on wcf service side, This policy should be compatible with WCF service security policy)

SAMPLES:

SAMPLE1:

WSE->WCF interop(Anonymous certificate)

http://www.kioskotobys.com.ar/WSEAndIndigo.zip

SAMPLE2:

WSE->WCF interop (Kerberos)

http://blogs.msdn.com/madhuponduru/attachment/594770.ashx

CLIENT SIDE:

Modify client policy file, change the host name to your machine name and

SAMPLE3:

Sample 3 also will be using custom binding, Microsoft providing custom binding code, please use this approach, sample1 and sample2 to understand more about WCf->WSE interop internals.

WSE->WCF interop with custom binding (custom binding)

WSE team found, above approach may confuse customers, so they wrote custom binding to solve WSE->WCF interop problem, we have to reference wsehttpbinding class library in your project ,and then change all the settings programmatically

http://blogs.msdn.com/madhuponduru/attachment/577903.ashx

Note:

Please run setup.bat(run it from SDK command prompt, please make sure, you are able to run makecert,certmgr commands from command window)

How to enable WCF tracing

madhu_ponduru@hotmail.com — Fri, 19 May 2006 03:48:00 GMT

How to enable WCF trace:

Open config file in svcconfigeditor, from wizard, you can enable tracing and logging

STEP1:

Open config file in svcconfigeditor

STEP2:

Select Diagnostics option on left side, you will see Different tracing options on right side

STEP3:

If you just want to log soap request and response, you can choose Message Tracing
If you want trace service creation and all other activities, you can enable service tracing

Once you choose one of those options, you can choose, what level of tracing you want

(Like Verbose, or you want trace only error messages)

STEP4:

Click on Message Tracing, you will see different Message logging options, you can choose, you want to log Message at Transport level or Service level.

Reference:

http://msdn.microsoft.com/en-us/library/ms732009.aspx

Ok, Now I got trace file, How to view trace file:

Once you have log file, you can open client side trace and service side trace file in svctraceviewer and you can filter trace by different categories

MORE INFO:

The Diagnostics tab enables you to turn performance counters on or off, enable or disable Windows Management Instrumentation (WMI), configure WCF tracing, and configure Windows Communication Foundation (WCF) message logging.

To control performance counters and WMI

Click the Diagnostics tab.
To turn on WCF performance counters, select the Enable Performance Counters check box. Clear the box to turn off the counters.
To turn on WMI, select the Enable WMI check box. Clear the box to disable WMI.

Configuring Tracing

You can create a WCF trace file with standard properties or set up a custom trace file.

To create a trace file with standard properties

Click the Diagnostics tab and click Tracing.
In the Diagnostics Tracing window that opens, click Create.
Choose a location for the trace file, and click Save.
Click OK to return to the Service Configuration Editor window.

To create a custom WCF trace file, you must configure both a source and listener.

To create a custom WCF trace file

Click the Diagnostics tab, and then click Tracing.
In the Diagnostics Tracing window that opens, on the Listeners tab, click Add.
Enter the parameters for your trace file. Clicking the TypeName line displays a "…" button. Click the "…" button to open Trace Listener Type Browser, which you can use to find preconfigured trace listeners that are already installed.
Note the Source section. Click Add in this section to open a dialog box with a drop-down menu listing available tracing sources. Select a tracing source and click OK.
To apply your changes, click OK on each window until you return to the main Service Configuration Editor window.

Configuring Message Logging

You can create a WCF message logging file with standard properties or set up a custom logging file.

To create a message logging file with standard properties

How to extend wcf service functionality without breaking existing clients (Thinking about old COM rules)

madhu_ponduru@hotmail.com — Sun, 26 Feb 2006 04:49:00 GMT

I was thinking about, How to extend service functionality without breaking existing clients (Thinking about old COM rules)

COM interface rules still apply to wcf contract.

Contract/service level:

(1)Adding new method to the service won’t break existing client

(2) Implementing new interface won’t break existing clients

Only requirement is, we should not change method signature for existing methods

Data contract level:

We have very good sdk sample to demonstrate, How to maintain data contract versions
