Simple Tutorial: Host a WCF Service in the Sandbox

This is based on the tutorial at http://community.discountasp.net/showthread.php?t=7719&highlight=EvalService
which, in my opinion, is WAY too complicated.

Here are all the steps you need to take to host a WCF service in the ASP.Net 4.5 Sandbox. (Yes, you must first get a sandbox account, username and password). I've used the Visual Studio 11 Beta, but this should be fairly similar in VS2010.

1. Open VS2011.
a. Select: File->New->Project
b. At the top of the "New Project" dialog, make sure ".NET Framework 4.5" is selected.
c. Select: Project types="Visual C#"->"WCF" (or "Visual Basic" -> "WCF")
d. Select: Templates="WCF ServiceLibrary"
e. Set: Name="TestWcfServiceLibrary"
f. CheckBox: Create directory for solution=true
h. Set: Solution Name="TestWcfServiceLibrary"
i. Select: "OK"

2. In the main menu
a. Select "File"->"Add New Web Site"
b. Select Template="WCF Service"
c. Set Filename=[ANYWHEREYOUWANT]
d. Set Language="Visual C#" (or Visual Basic)
e. Click "OK"
f. Build the solution

3. Open up FTP or Windows explorer
a. login to the sandbox site (netfx45lab.discountasp.net -- the server will navigate to the proper folder based on your login)
b. Copy Drag and drop the files in [ANYWHEREYOUWANT] to your base FTP directory.
c. Verify with a web browser pointed to "http://YOURSANDBOXUSERNAMEHERE.netfx45lab.discountasp.net/Service.svc"

4. Access the service with a simple Windows app
a. Open VS (any version)
b. On the File menu, click Add, then New Project
c. In the New Project dialog, expand the Visual C# node and select Windows Forms Application.
d. Give the project any name you want.
e. Click "OK" to create the project.
f. In Solution Explorer, Right-click your project and click "Add Service Reference"
g. In the Address field, enter "http://YOURSANDBOXUSERNAMEHERE.netfx45lab.discountasp.net/Service.svc"
h. Click "Go"
i. Click "OK"
j. Double-click Form1 to open it in the designer
k. Add two text boxes and one button. By default, they will be named button1 textBox1 and textBox2
l. Double-click the button and in the button1_Click event handler, add the following code:
ServiceReference1.ServiceClient client = new ServiceReference.ServiceClient();
textBox2.Text = client.GetData(System.Int32.Parse(textBox1.Text));
m. Run your project.
n. Enter an integer in textBox1
o. Click the button
p. You'll see the service response in textBox2

That's all there is to it.
