This freeware Visual Studio 2003 add-in provides a multi-language spell checker for your comments and string literals. Without setting any options it knows how to spell check C#, VB.NET, C++.NET,  J#, C/C++,  HTML, XML, Java, and other text-based files. It works on the selected code or on the entire current file or project, and has many other options. Version 2 fully works with ASP.NET and Web Services projects.

You are only required to have MS-Word 2000 or higher because this add-ins needs the objects they expose.

edtFTPnet is the first choice of .NET developers worldwide for
incorporating FTP functionality into their applications.

• Widely used throughout the world in many projects.
• Full source code is provided.
• Passive and active modes are supported (PASV and PORT).
• Resuming of interrupted binary transfers supported.
• Events for monitoring progress of data transfers.
• Under the LGPL, so it can be embedded in commercial applications.
• Mature and stable codebase.
• Simple but extensive API analogous to a command line FTP program.

There are various different ways of implementing the singleton pattern in C#.

The implementation that listed below  is thread-safe, simple, and perform well.

public sealed class Singleton

{

    Singleton()

    {

    }

    public static Singleton Instance

    {

        get

        {

            return Nested.instance;

        }

    }

    class Nested

    {

        // Explicit static constructor to tell C# compiler

        // not to mark type as beforefieldinit

        static Nested()

        {

        }

        internal static readonly Singleton instance = new Singleton();

    }

}
