WCF Service + Entity Framework: How to send an entity? - wcf

some of my methods in the WCF Service returns an entities from the Entity Framework. I cannot add the Web Service reference in my Windows Phone 7 application because of that warning:
Custom tool warning: Cannot import
wsdl:portType Detail: An exception was
thrown while running a WSDL import
extension:
System.ServiceModel.Description.DataContractSerializerMessageContractImporter
Error: Could not load type
'System.Runtime.Serialization.DataContractSet'
from assembly
'System.Runtime.Serialization,
Version=2.0.5.0, Culture=neutral,
PublicKeyToken=7cec85d7bea7798e'.
XPath to Error Source:
//wsdl:definitions[#targetNamespace='http://tempuri.org/']/wsdl:portType[#name='IBarnGameServiceNEW'] D:\MGameWindowsPhone7\Service
References\ServiceReference3\Reference.svcmap
What's the reason ?

Run Visual Studio not under Administrator account. This helps me.

Deploying WCF Service on Non SharePoint Envirnment

I have a plain .Net based WCF Service which is interacting with SharePoint (2010) Site. I need to deploy it on the Production environment which is not a SharePoint environment. After creating and deploying the solution its giving error
"Could not load file or assembly 'Microsoft.SharePoint.Library, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' or one of its dependencies. The system cannot find the file specified "
Please help me with the steps to create a deployment package for NON-SharePoint Environment.
Thanks

If you are deploying your WCF on non-Sharepoint environment, You cannot use Sharepoint server object model inside wcf.
You need to use Client object model and add reference to Microsoft.Sharepoint.Client and Microsoft.Sharepoint.Client.Runtime

Microsoft Service Configuration Editor - Could Not Load File Or Assembly

I'm getting stumped by a very basic error. I'm trying to add endpoints to a service through the WCF Service Configuration Editor, and it can't find the default output. Here's every step I can take to reproduce the error.
Add New WCF Service Application
Build Solution
Edit WCF Configuration
Create New Service
Browse to Project Directory for Service Type
Error Message
This should work, but instead I get the following error message:
Could not load file or assembly
'file://...\emptyservice\bin\EmptyService.dll'
or one of its dependencies.
Operation is not supported.
(Exception from HRESULT: 0x80131515)
What am I doing wrong?
Make sure you open the 'EmptyService.dll' library in your 'bin\Debug' folder.
I had the '... Operation is not supported. (Exception from HRESULT: 0x80131515)' message when trying to open the library in the 'publish' folder. I published my service from within Visual Studio using the 'Publish Web Site' option.

WCF Service Error on generate code file with SVCUtil

I created a WCF service with net framework 4.0 on Windows OS;
and its works OK use SVCUtil to generate client code file.
but its failed on ubuntu apache with mono.
error info below:
exception :System.ServiceModel.Description.DataContractSerializerMessageContractImporter
details:
Due to the namespace "http://schemas.datacontract.org/2004/07/System" with data
contract name "MarshalByRefObject" reference types "System. MarshalByRefObject,
mscorlib, VerSion = 4.0.0.0, Culture = neutral, PublicKeyToken = b77a5c561934e089 "
with import DataConTract does not match, so can't use. you need to remove the
type of the reference.
but how can i remove the type of the reference MarshalByRefObject on mono?
Any assistance would be appreciated. Thanks a bunch for your help.

WCF Enterprise Library ExceptionHandling failing when faultcontracttype in other project

Background: I have a WCF project that is using Microsoft Enterprise Library WCF Exception Handling.
We recently decided to move our operation and data contracts into a separate project (.net assembly) called comanynamespace.xxx.WCF.Utilities. After moving the operation and data contracts, I changed the faultContractType namespace to reflect the new assembly.
Now when I launch the web service in VS2010 I get the following error:
Activation error occured while trying to get instance of type ExceptionPolicyImpl, key "WCF Exception Shielding"
I have tried: ensuring the same references exist in both projects and ensuring that both projects are running under .net 4 (no client modes), etc. Neither helped resolve the issue.
Finally, I copied the Service Fault class back into the Web Service project and changed the namespace in the web.config to point back to the local namespace:
from:
faultContractType="comanynamespace.xxx.WCF.Utilities.ServiceFault, comanynamespace.xxx.WCF.Utilities.Services"
to:
faultContractType="comanynamespace.xxx.Web.Services.ServiceFault, comanynamespace.xxx.Web.Services"
This does resolve the error, however, now I must have my service fault data contract in both locations.
Does anyone know why I am unable to use a service fault (data contract) in another .net assembly with Microsoft EL WCF Exception Handling?
The problem ended up being that the namespace (second part) of the faultcontracttype was set to
faultContractType="companyname.xxx.WCF.Utilities.Services.ServiceFault, companyname.xxx.WCF.Utilities.Services"
instead of
faultContractType="companyname.xxx.WCF.Utilities.Services.ServiceFault, companyname.xxx.WCF.Utilities"
companyname.xxx.WCF.Utilities is the namespace for the assembly.

Error message from svcutil.exe - what does it mean?

I've had not a lot of luck creating a WCF service with Visual Studio. It's in IIS, and it I click 'browse' on the .svc file itself, it tells me I have created a service. So I assume it's all okay to a point.
Throughout my time I came across a recommendation to use a program called svcutil.exe. I used it on my service and got the following error. I don't know what it means, so hopefully someone can shed some light on the situation.
Here's the result:

Warning: No code was generated.
If you were trying to generate a client, this could be because the metadata docu
ments did not contain any valid contracts or services
or because all contracts/services were discovered to exist in /reference assembl
ies. Verify that you passed all the metadata documents to the tool.
Warning: If you would like to generate data contracts from schemas make sure to
use the /dataContractOnly option.
I think this previous Stack Overflow question may help with your current question but not necessarily your problem.
Error: Cannot import wsdl:port with svcutil
You've created your WCF service and you've browsed to it in IIS so you're happy that it is working. The purpose of SVCUtil.exe is to generate classes that you can use in an application to interact with the service with compile time information on the contract members and methods.
it performs the exact same function as adding a service reference in visual studio to consume the service.
If your having trouble, i'd suggest just creating a simple console project in visual studio, adding a service reference and giving it the url of the service you've hosted in IIS. Then click "show all files" in the visual studio solution explorer and look at the reference.cs file it gives you. This will show you what information has been consumed from your service.
Edit
Hi Again,
After going through all the comments below I'm starting to see more about your problem. I think you misunderstand what it is your doing when in fact you've already achieved what you want to achieve.
The original project, the one you had with the WCF test client that worked did what you needed. It is a fully fledged WCF Service. All you needed to do was right click the solution in visual studio and publish it. If you then make sure that you make an IIS virtual directory point at your solution, through the publish wizard. Then when you run your project and then browse to that url, that will give you a service to consume for testing purposes.
What you are doing at the moment, creating a WCF project, adding that DLL to a website project is fundamentally wrong: The example you followed, presumably this one :
http://msdn.microsoft.com/en-us/library/ms733766.aspx
is about creating a WCF service in a web site project from scratch. Not about adding a pre-existing WCF project and hosting it.
Your essentially trying to do one thing in two different ways together.
Your current course of action is to either remove the DLL in your web project and then create the service there. Or host your current WCF service in IIS ( the project you downloaded from me or your original one)
At this point you have a hosted service. Then usually you have an application to interact wtih it. This you found using svcutil and can be done in one of two ways:
You create the console application and do "Add Service Reference" to the URL you have hosted in IIS.
Or you use SVC Util.exe point it at the url which generates a class file you include in your console / application.
I hope that clears things up about WCF and what stages to use various tools?
Edit 2
Just in case you don't get to the Chat:
I still think theres something wrong with your original project. I'm not sure what you mean by the one with the DLL either? if that means your website project with the dll of the WCF project, then no not that one.
I've taken the project I sent you earlier. I've hosed that in IIS so that when i browse to localhost/EvalService on my machine i get the standard
"EvalService Service
You have created a service.
To test this service, you will need to create a client and use it to call the service. You can do this using the svcutil.exe tool from the command line with the following syntax:"
Once I had that set up i created a console application, "added service reference" in visual studio and it consumed teh service no problem.
Try doing the above with the project I sent you and see how far you get.
