IIS Hosting Using Inline Code

Download sample

This sample demonstrates how to implement a service hosted by Internet Information Services (IIS), where the service code is contained in-line in a .svc file and is compiled on demand. Service code can also be implemented directly in source code files located in the application's \App_Code directory, or compiled into assembly deployed in \bin. This sample does not demonstrate these techniques.

NoteNote:

The setup procedure and build instructions for this sample are located at the end of this topic.

The sample demonstrates a typical service that implements a contract that defines a request-reply communication pattern. The service is hosted in IIS and the service code is entirely contained in the Service.svc file. The service is host-activated and compiled on-demand by the first message sent to the service. There is no pre-compilation necessary. The service implements an ICalculator contract as defined in the following code:

// Define a service contract.
[ServiceContract(Namespace="http://Microsoft.ServiceModel.Samples")]
    public interface ICalculator
{
    [OperationContract]
    double Add(double n1, double n2);
    [OperationContract]
    double Subtract(double n1, double n2);
    [OperationContract]
    double Multiply(double n1, double n2);
    [OperationContract]
    double Divide(double n1, double n2);
}

The service implementation calculates and returns the appropriate result.

<%@ServiceHost language=c# Debug="true" Service="Microsoft.ServiceModel.Samples.CalculatorService" %> 
…
// Service class that implements the service contract.
public class CalculatorService : ICalculator
{
    public double Add(double n1, double n2)
    {
        return n1 + n2;
    }
    public double Subtract(double n1, double n2)
    {
        return n1 - n2;
    }
    public double Multiply(double n1, double n2)
    {
        return n1 * n2;
    }
    public double Divide(double n1, double n2)
    {
        return n1 / n2;
    }
}

When you run the sample, the operation requests and responses are displayed in the client console window. Press ENTER in the client window to shut down the client.

Add(100,15.99) = 115.99
Subtract(145,76.54) = 68.46
Multiply(9,81.25) = 731.25
Divide(22,7) = 3.14285714285714

Press <ENTER> to terminate client.

To set up, build, and run the sample

  1. Ensure that you have performed the One-Time Setup Procedure for the Windows Communication Foundation Samples.

  2. To build the C# or Visual Basic .NET edition of the solution, follow the instructions in Building the Windows Communication Foundation Samples.

  3. To run the sample in a single- or cross-machine configuration, follow the instructions in Running the Windows Communication Foundation Samples.
