I have one solution WCFSampleSolution and it has all my projects - Web Service, Client and Website. The structure is something like:
WCFSampleSolution
C:\WCFSample\Website
WCFService
WCFWebClient
I created WCFService project for my services. It contains IService1.cs and Service1.cs. Then I hosted the service in IIS. I did this by creating a website and adding .svc and web.config files to the website project. Then published it in IIS. When I run http:\MyMachineName\Website\Service.svc, it shows the service description. Then I create the web client that calls the webservice. I used the service reference to add the service. It calls a method of Service1. It works fine. But I amnot able to debug this program/setup. I verified the config files in WCFWebClient project and Website project and they have proper debug settings.
<compilation debug="true">
I put break points but control never goes to my seb service. I also tried attach process, but it also doesn't work. But I was able to debug one of my other WCF projects. The setup was little different. In that project I copied the .svc file and config in my web client and the debug works fine.
Please HELP!!
You are hosting your service on IIS so I am sure you must be attaching to w3wp.exe process. While trying to attach if VS built in web server is starting, then attach to that process as well.
What I find particularly easy is having two instances of visual studio open (especially if you use NUnit or doing anything to test out code). One will attach NUnit or whatever you wish, and the other will attach the w3wp.exe process. The easiest way is to:
1) Put a break point in the 1st instance of visual studio of the code right before it will hit the WCF service hosted on your machine.
2) Once the code stops at your breakpoint, set breakpoints in the 2nd instance of visual studio where you want to break then attach the w3wp.exe process.
3) Once you continue, the breakpoint on the service code should be hit.
It is sometimes easier to find the process id as well when attaching w3wp.exe. Using IIS, you can go to "Worker Process" and find the process id to attach for your Application Pool Name.
#user465876 - another approach that is less of a hassle can be found here: WCF can no longer step into a service that's locally hosted -- why not?

I want to start an default webservice-project, where I can send data over a service. When I go to debug the API through VS then everything works fine, but not when I try to use it over IIS.
I created an WcfServiceLibrary-Project in Visual Studio 2017. I then right-clicked on the project (in the solution explorer) and then published it to a folder A.
I also didn't do anything special at IIS (all the things are still on localhost.): I activated the default windows-feature "IIS". (The default web site got also stopped). Then I added there a site with an random name and the path to the folder A. The service got started.
My access trial was to find anything through Visual Studios "connected services".
Has anyone an idea?
At first, please use the WCF service application project template,
or the Appconfig file would not be kicked in. library project needs the additional configuration in the hosting environment, and the Appconfig file could not recognized. We have to move the configuration code into the configuration file recognized by your hosting environment.

Secondly, for hosting the WCF service in IIS, we should enable the below windows feature.
Feel free to let me know if the problem still exists.
I have a solution with several WCF self hosted projects. Every time i run a uni test i message box with this message pops up.
Because the projects were not created as WCF projects, they don't have the WCF tab in properties page were, according to many posts, i should be able to fix it by disabling option Start WCF Service Host when debugging another project in the same solution
I am running on VS 2017.
Any pointers?
Found out.
The problem was that i had a WCF Library project in the solution that was created as a regular Library project.
I fixed by adding the followin XML tag to the library project:
<ProjectExtensions>
<VisualStudio>
<FlavorProperties GUID="{3D9AD99F-2412-4246-B90B-4EAA41C64699}">
<WcfProjectProperties>
<AutoStart>False</AutoStart>
</WcfProjectProperties>
</FlavorProperties>
</VisualStudio>
</ProjectExtensions>
To get the tag, case anyone wonder what is it, i created an WCF library project on a dummy solution, uncheck the Start WCF Service host when debugging another project in the same solution as show in the picture below, and grab the tag from the config file.
i have 2 systems, one is localhost(Windows 8.1Pro) and another is Virtual Machine(Windows server 2008R2).
i have a silverlight app hosted in VM which is consuming WCF service from localhost installed in windows service.
Problem:
silverlight is not getting clientaccesspolicy.xml and crossdomain.xml so wcf service will not fetched.
Tried solutions:
Added clientaccesspolicy.xml and crossdomain.xml in WCF service solution before installing but still it can't be fetched from WCFservice url.
Added clientaccesspolicy.xml and crossdomain.xml in C:\inetpub\wwwroot folder, as per my search so many suggested to place their which will be automatically fetched by silverlight.
tried adding clientaccesspolicy.xml code into wcf service as per this link still no success.
Any suggestions will be appreciated.
Edit:
okay i am attaching code FYR, i am doing this as below.
once i build WCFTest , 'll get .exe wcf installer which i am installing that using installutil.exe, so service'll be up and running in services.msc.
once i build TestSL, 'll get TestSLTestPage.html , on double clicking on this it'll open in IE, and on button click i should get "Hello World" from WCF.
Download it from here and suggest me if i am doing anything wrong. Attached projects are of exact same structure as i am workinig on....

as i explained my prob.above i was using self hosted Wcf service and i couldn't solve the problem so Here's what i did
1. Created Default WCF Service application in VS2013 with all my code and added clientaccesspolicy.xml and crossdomain.xml in the solution.
2. Created a new website in IIS Manager to publish my project.
3. and published my project to IIS as filesystem.
4. There we'll have all the files that are necessary.
And Voila everything works perfect.
Hope it helps somebody.
On my local machine, I consume a WCF service via the Service References. I can add to the other WCF project and check in to TFS , run the service, Go to my main project and Click on Update Service Reference, and my web.config is fine whether change is needed or not. Rebuild is fine.
However, on another developer's machine, they make a change to the WCF Service run it, and go to main project and Update Service Reference, and sometimes the web.config get trampled, it doesn't show the Url to the wcf service etc... Thus compiling project causes a issue where it cannot find the namespace for the service reference.
Then if I get latest and checkin and tell a developer to get latest, their web.config will update, but they still increasingly have a problem with the namespace for the service reference does not exist. It is running, the update to the service works. The Url in the browser shows the endpoints.... but vs 2010 sp1 has repository files that cannot find the service reference for some reason. "Are you missing an assembly reference?" Any ideas??
If in the svcutil dialog, the option to use shared assemblies is turned on, and if any signed assemblies are not an exact match, the checked in version will fail on the other machine.
You need to make sure the assemblies used have the same public key token.
I have 1 c# Console Application project, which has Program.cs (that contains main method), the main method simple calls a web service method and displays the string on the console.
The service reference is added in the project by right clicking it and adding service reference it to it.
when the console application is executed in debug mode from visual studio, it works as expected.
when the console application is executed from a .exe found in /bin/debug, it works as expected.
so far so good.
PROBLEM:
when the project is copied over to the system (you can call it a production environment), where this .exe will actually be executed, it fails at the exact line where i create the service proxy object. the line in Program.cs is:
ProjectName.ServiceReference.ServiceClient service = new ProjectName.ServiceReference.ServiceClient();
I know it fails here, because i have Console.Writeline("some line"); before and after the above line. I can see the Console.Writeline that is before the proxy line, and soon after that it crashes ...
I think this is because the reference paths that are referencing the service, is there any thing i can do to change the paths, or confirm that it is the path issue as suspected ...??
any idea whats going wrong ..???
Check this link: http://blog.davidsandor.com/post/Workaround-The-configuration-for-the-servicee280a6Unrecognized-element-e28098extendedProtectionPolicye28099.aspx
The configuration for the service reference could not be updated due
to the following issue: Unrecognized element
‘extendedProtectionPolicy’. (App.config / Web.config)
There does not seem to be a really clear reason why this is happening
however it seems to be related to Windows 7. I am not sure if the
.NET framework that ships with Win7 has some different setting or
template for the WCF configuration policy files but it seems to be the
culprit. Maybe the machine.config files are different on Win 7 and
the WCF configuration tools use the machine.config as some sort of
policy template.
The fix is annoying (because every time you build your solution on
Windows 7 and then rebuild on Vista you have to redo this).
Remove the line:
<extendedProtectionPolicy policyEnforcement="Never" />
from both your App/Web.config file on the client and on the WCF
server’s Web.config file.
