Tôi có một cái gì đó như thế này:Hosting một dịch vụ WCF thành một vấn đề trang web: System.ArgumentException: ServiceHost chỉ hỗ trợ loại hình dịch vụ lớp
MathServiceLibrary (Thư viện dịch vụ WCF)
[ServiceContract]
public interface IMathService
{
[OperationContract]
int Add(int x, int y);
[OperationContract]
int Multiply(int x, int y);
}
public class MathService : IMathService
{
public int Add(int x, int y)
{
return x + y;
}
public int Multiply(int x, int y)
{
return x * y;
}
}

contract="MathServiceLibrary.IMathService" />
<host>
<baseAddresses>
<add baseAddress="http://localhost:8080/" />
</baseAddresses>

</service>
</services>
Nếu tôi chạy điều này tôi có thể thấy WCF Test Client và mọi thứ đều ổn.
Bây giờ tôi muốn lưu trữ dịch vụ này vào IIS vì vậy tôi tạo một trang web và thêm tham chiếu đến MathServiceLibrary.
Tôi có điều này ms.svc
<%@ ServiceHost Language="C#" Debug="true"
Service="MathServiceLibrary.IMathService" %>
và điều này web.config
<system.serviceModel>
<services>
<service behaviorConfiguration="defaultServiceBehavior" name="MathServiceLibrary.MathService">
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
<endpoint address="" binding="wsHttpBinding" contract="MathServiceLibrary.IMathService">
<identity>
<dns value="localhost"/>
</identity>
</endpoint>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="defaultServiceBehavior">
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
Khi tôi bấm chuột phải vào ms.svc xem trong trình duyệt của tôi có được điều này:
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

cảm ơn, nó hoạt động. – gigi
