The configuration for a simple http WCF host is:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
  </appSettings>

  <system.serviceModel>
    <services>
      <service name="AssemblyNamespace.ServiceImplementation"
               behaviorConfiguration="ServiceBehavior">
        <endpoint address="ServiceName"
                  binding="basicHttpBinding"
                  contract="AssemblyNamespace.ServiceContractInterface" />

        <endpoint address="mex"
                  binding="mexHttpBinding"
                  contract="IMetadataExchange" />

        <host>
          <baseAddresses>
            <add baseAddress="http://HostName:Port/"/>

        </behavior>
      </serviceBehaviors>
    </behaviors>

  </system.serviceModel>
</configuration>

The Service

Define the service in an interface

using System.ServiceModel;

namespace TestService
{
    [ServiceContract]
    public interface ICalculator
    {
        #region Instance Methods

        [OperationContract]
        double Add(double n1, double n2);

        [OperationContract]
        double Divide(double n1, double n2);

        [OperationContract]
        double Multiply(double n1, double n2);

        [OperationContract]
        double Subtract(double n1, double n2);

        #endregion
    }
}

Then implement the interface

using System;

namespace TestService
{
    public class CalculatorService : ICalculator
    {
        #region ICalculator Members

        public double Add(double n1, double n2) {
            double result = n1 + n2;
            Console.WriteLine("Received Add({0},{1})", n1, n2);
            Console.WriteLine("Return: {0}", result);
            return result;
        }

        public double Divide(double n1, double n2) {
            double result = n1/n2;
            Console.WriteLine("Received Divide({0},{1})", n1, n2);
            Console.WriteLine("Return: {0}", result);
            return result;
        }

        public double Multiply(double n1, double n2) {
            double result = n1*n2;
            Console.WriteLine("Received Multiply({0},{1})", n1, n2);
            Console.WriteLine("Return: {0}", result);
            return result;
        }

        public double Subtract(double n1, double n2) {
            double result = n1 - n2;
            Console.WriteLine("Received Subtract({0},{1})", n1, n2);
            Console.WriteLine("Return: {0}", result);
            return result;
        }

        #endregion
    }
}

The Host

Lastly create a host for the service

using System;
using System.ServiceModel;

namespace TestService
{
    internal class Program
    {
        #region Class Methods

        private static void Main() {
            using (ServiceHost serviceHost = new ServiceHost(typeof (CalculatorService))) {
                serviceHost.Open();

                Console.WriteLine("The calculator service is ready.");
                Console.WriteLine("Press <ENTER> to terminate service.");
                Console.WriteLine();
                Console.ReadLine();
            }
        }

        #endregion
    }
}

Currently there are two relevant builds of Subversion, one based on apache 2.0 and one based on 2.2. I am going to install Apache 2.2 and the corresponding Subversion build.

Install the Apache HTTP server.

Download and run the latest subversion build (currently svn-1.4.6-setup.exe) from http://subversion.tigris.org/servlets/ProjectDocumentList?folderID=8100&expandFolder=8100&folderID=91

Copy the file mod_dav_svn.so from C:\Program Files\Subversion\bin to C:\Program Files\Apache Software Foundation\Apache2.2\modules.

Open the Apache configuration file (‘Start > All Programs > Apache HTTP Server 2.2 > Configure Apache Server > Edit the Apache httpd.conf Configuration File’) and find the line ‘#LoadModule dav_module modules/mod_dav.so’.

Remove the ‘#’ from the front of that line then add the line ‘LoadModule dav_svn_module modules/mod_dav_svn.so’ below it. Save the file and restart the service to confirm everything is working as it should.

Create the directory where you want to store the repositories (e.g. D:\Svn).

Go back to the Apache configuration file and at the end of the file add:

<Location /Svn>
    DAV svn
    SVNListParentPath on
    SVNParentPath D:\Svn
</Location>

Save the changes then restart the Apache service for them to take effect.

You should now be able to browse to http://localhost:81/Svn/ and see a page with zero repositories.

Download
The latest Apache build (currently apache_2.2.9-win32-x86-no_ssl-r2.msi) from http://httpd.apache.org/download.cgi

Install Apache
Run the installer and follow the instructions. Enter the server name under ‘Network Domain’ and ‘Server Name’, enter an email address and leave ‘for All Users’ selected.

Navigate to http://localhost/ and you should see the text ‘It works!’.

I prefer to run IIS on port 80 and Apache on 81. If you already have IIS installed and running you may not have got the ‘It works!’ page but rather an IIS page when running the test above.

Change to Port 81
‘Start > All Programs > Apache HTTP Server 2.2 > Configure Apache Server > Edit the Apache httpd.conf Configuration File’

Search for  ‘Listen 80′ and replace with ‘Listen 81′

Save the conf file and restart the service from the services console then browse to http://localhost:81/ to confirm it works.

Create a Password File
Open a command prompt at C:\Program Files\Apache Software Foundation\Apache2.2.

Create a password file by entering ‘bin\htpasswd -c passwd username‘ and enter and confirm the password when prompted.

Add any further users with ‘bin\htpasswd passwd username‘.

Edit the Apache httpd.conf configuration file and change:

<Directory />
    Options FollowSymLinks
    AllowOverride None
    Order deny,allow
    Deny from all
</Directory>

To:

<Directory />
    Options FollowSymLinks
    AllowOverride None
    Order deny,allow
    Deny from all
    AuthType Basic
    AuthName “Subversion Repositories”
    AuthUserFile passwd
    Require valid-user
</Directory>

Restart the Apache 2.2 service and confirm you are asked for a username and password when you navigate to http://localhost:81/.

You may need to amend your firewall to allow connections from port 81.

This means when you run your Windows Complete PC Restore, either from Vista or by choosing repair your computer during an installation, and insert the first disk of the back up when asked to insert the backup media you get the message “No valid backup locations could be found” which initially is just a bit worrying.

If you insert the last disk of the backup set, the catalogue is found and you can choose the backup and the backup options you want. When the backup starts you will be asked to insert the first disk.

public sealed class Singleton
{
   private static Singleton _instance = new Singleton();

   private Singleton() { }

   public static Singleton Instance
   {
      get
      {
         return _instance;
      }
   }
}

As the CLR synchronises static constructors it is thread safe. Also static constructors are not called until the types is accessed to you have lazy instantiation (use nesting if there are other static methods).

Confusingly, looking at a shortcut’s properties, the compatibility tab has an option to “Run this program as an administrator”. This option is greyed out:

To set the shortcut to run as administrator go to the shortcut tab > click on Advanced… > check Run as administrator:

• The item body is copied to the task body and the item itself is added as an attachment.
• If multiple items are selected, multiple tasks will be created.
• Created tasks are left open for editing.
• I am in two minds about deleting the item after the task is created and have decided against it at the moment.
• It appears that OL 2007 does not allow shortcut keys to be assigned to macros .

This could be caused by an incompatible display driver. I solved this problem by:

1. Reboot the machine and hit F8 to get the Windows boot menu.
2. Select Safe Mode with Networking.
3. Vista will boot then will complain that it cannot continue with the installation in Safe Mode. Do not hit OK!
4. Press Shift + F10 to get a command window.
5. Run Device Manager by entering ‘devmgmt.msc’.
6. Right click the video card and select Update Driver.
7. Choose ‘Select a Driver’.
8. Select ‘Choose from a list’.
9. Click on the generic VGA driver and hit Next to install it.
10. Close the wizard, close the Device Manager, close the command prompt.
11. Click OK on the installation message and Vista will reboot.
12. Finish the install, create a restore point, then install the correct video driver.

You can allow other assemblies access to your internal types and members though, by using the InternalsVisibleTo attribute. This is especially useful for allowing your test assembly to access your internal classes.

This attribute can only be applied to strongly named assemblies.

[assembly:InternalsVisibleTo("TestAssembly, PublicKey=TestAssembly’s public key")]

The attribute requires the assembly name and the public key. To retrieve the public key use sn.exe. Open a visual studio command prompt and enter:

sn.exe -Tp AssemblyPath

Alternatively if you use an alternate file explorer you could set up a macro.
