I've built and compiled my WCF client to run successfully. I've found that as long as these two files are together, my client will run anywhere on my computer:
Client.exe
Client.exe.config
When I move these files to another computer, there's an error:
System.InvalidOperationException: Could not find default endpoint element that
references contract 'Service.IService' in the ServiceModel client configuration
section. This might be because no configuration file was found for your
application, or because no endpoint element matching this contract could be
found in the client element.
I've already made sure that the service URL is accessible from the intended host of the computer.
After looking up the issue, seems like a solution is to copy the config retrieved from executing:
svcutil http://host/Service.svc
to the application configuration file. However, the config info is already in the App.config file when I built the project.
Do I need to recompile/build on every client machine that intends to use the WCF web service?
I seem to have resolved this by copying over the entire compiled folder:
Client.exe
Client.config.exe
Client.pdb
Client.vshost.exe
Client.vshost.exe.config
I don't have the time to go back and forth to see which subset of files are core or whether all these files are necessary, but hopefully someone can follow up with an answer to that.

I am having troubles hosting the blazor wasm asp.net core hosted application.. The solution has 3 projects: Client, Shared, and Server.
when I run the command dotnet publish --configuration Release it publishes the libraries to their respective folders in solution like this:
WebWorkbench3\Client\bin\Release\net5.0\publish
WebWorkbench3\Server\bin\Release\net5.0\publish
...
I would assume that since the server project is referencing a client - then my steps to host the application are following:
Open WebWorkbench3\Server\bin\Release\net5.0\publish in powershell
Run command dotnet .\WebWorkbench3.Server.dll
Navigate to: https://localhost:5001/
Result:
Expected: client page opened
Actual: page is stuck at "Loading.." string. In the console we see that there was an error about _framework/blazor.webassembly.js not being loaded.
If we were to check the wwwroot folder contents in the server app we will see the following:
So this explains why the error is shown. However my question at this point - should the publishing process/configuration in project take care of copying client's wwwroot contents into the the server's app output directory? If we start a debugging session in the VisualStudio, then we use the server as the startup point, so the project should have some idea where to look up the blazor.webassembly.js file at..
So why doesn't the same process occurs during the publishing?
Note: I was able to fix the issue by manually copying the client's wwwroot directory and by placing the contents into the server's wwwroot directory... But I don't think that is is how serving is supposed to work?
EDIT: I have just tried to set-up the client blazor application in IIS. And it works. Kind of. The page is opened. But then when it tries to make a REST GET request to the server - it uses the same hostname:port combination. So if my app is hosted on mysite.local:50001 then the request to API will look like mysite.local:50001/data/loadall where data is the controller name and loadall is the action name.. So basically the client uses the same base address as the server.. The problem, is that I cannot start the server on the same port as the client! In attempt in doing so - you will see following output:
So basically I have the same question as before - how to host the wasm application that is split between client and the server? I am pretty sure that I can make it work by forcing the client to use the non-standard server port and serving the server part on that port.. However, I believe there should be a reason why current configuration (default configuration in the blazor wasm template) is configured in this way so it should be possible to run the project somehow without any additional changes at all..
Well this will be a self-answer.. Instead of publishing (dotnet publish --configuration Release) the application on solution level - do the publishing on project level..
before ..\repos\WebWorkbench3\WebWorkbench3
after ..\repos\WebWorkbench3\WebWorkbench3\Server
In 1 case the compiler does not copy the _framework folder (and possibly some other files) into the wwwroot.. Once you have published the Server correctly you can access the app by serving it with dotnet .\WebWorkbench3.Server.dll command.
Having the samie issue as explained above:
Before:
The solution file
had the same name
was in the same folder
as the server project
Resolved
I moved the solution to the project root (one level up).
Now, dotnet publish within the server project produced the __framework folder + content as expected.
I have built an ESB Project with an HTTP endpoint. But for some reasons. The Endpoint that I have defined and added to the ESB Solution does not seem to be reflected in the project and seem to be not reflecting when I deploy to the server. The endpoint is basically not being used. I have also tried to check the under the Defined Endpoints tab in the server Enterprise Integrator console, #
Home > Manage > Service Bus > Endpoints
but it isn't there. Numerous restarts have not helped neither has undeploying and redeploying the car file. Can someone point out where I might have gone wrong? As usual, thanks in advance.
Could be different things, to check:
Extract the .car file (it's just a .zip, so rename or use 7zip to
extract) and see if your endpoint is there.
Check if the serverrole in the pom file is correct (should be EnterpriseIntegrator it think)
Sometimes renaming artifacts causes problems as the file does not get renamed correctly or a reference is not updated in one of the
project files. Try removing the endpoint and use 'search in files' to
remove any lingering references in pom files.
I'm trying to build a core with the routing service technology (in wcf .net) that discover its clients automatically with DiscoveryService and then write them into the config file with specific filters so that the core will be able to route messages between the clients.
I succeeded to discover the clients with DiscoveryService, but i'm trying to open new config file with the RoutingConfiguration object, and add the new endpoints I discovered through the RoutingConfiguration.filterTable property but it doesn't work. I also tried to look for examples in other sites but i didn't find anything similar.
I don't know if i'm making a mistake, or if I didn't understand well how to open new configuration file and edit it at runtime programatically.
I have more WCF services under an IIS virtual directory. I have to deactivate some of them and I thought, I have just commet out the appropriate sections in the web.config, but it seems not, the client works. Just in the browser comes the error message, that the metadata is not reachable.
Is it actually possible to somehow deactivate the services?
I had an another idea, to rename the .svc files, but I want to avoid that solution.
I am using .Net 4.0.
I've found that:
Simplified Configuration for WCF Services:
http://msdn.microsoft.com/en-us/library/ee530014%28v=vs.100%29.aspx
If you have only one service in the Web application, you may simply stop the app pool associated with the service, provided you have one app pool per web application.
If you have more than one services in the application and you just want to deactivate one,you may remove the respective svc file; or if you use config activation without any svc file, you may comment out respective line in the config. For more details about how to activate services without SVC files, you may read http://www.codeproject.com/Articles/627240/WCF-for-the-Real-World-Not-Hello-World and check the source codes attached in the article.
I have wcf client. It uses .NET 3.5.
When I compile the client I get two files:
client.exe and
client.exe.config.
The second file contains configuration for the wcf client.
In my case I need to prevent the user sitting on the computer to see the urls and change some other parameters from the config file.
So the requirements are, the end user not to see and modify the data stored in the config. The config file contains the same data as app.config. I need to forbid the person using the program to see the end point urls so easy.
Also I have a lot of configuration there so I do not like to code in the moment.
Is there any solution for the problem (embedded app.config of something else)?
Edit: I do not need configurable options. The config file is automatically created when adding service reference from the studio.

You can also create your proxies programatically instead of using the service reference feature.
Every parameter in the serviceModel config section can be represented in code as well.
The ChannelFactory class will help you create proxies to the service.
You can easily encrypt entire parts of your config files - and not just web.config in web scenarios, but also application config's in stand-alone apps.
Check out some resources on how to do this:
