Creating a Private Assembly

In Visual Studio .NET there is always an assembly whether you choose a class library

project or an exe project. Now, let’s start some practical work.

  • Start Visual Studio 2005
  • Choose a new C# project [File -> New Project]
  • Choosing new C#:project

  • From template pane choose Class Library Template
  • Set the Location : F:myWrittingsCSharpBookSource Codes
  • Name : privateAssembly
  • Check full code of private


  • In Solution explorer change class name from Class1 to mathclass
  • Now right click on mathclass and click on view code
  • Change the name of namespace from privateAssembly to CSharp.AStepAhead.privateAssemby
  • After writing codes of the assembly, now you have to provide some information to

    your assembly as follows:

using System.Reflection;

using System.Runtime.CompilerServices;

using System.Runtime.InteropServices; // General Information about an assembly is

controlled through the following

// set of attributes. Change these attribute values to modify the information

// associated with an assembly.

[assembly: AssemblyTitle(“privateAssembly”)]

[assembly: AssemblyDescription(“This is an Example of Book: C#-A Step Ahead


[assembly: AssemblyConfiguration(“Free I.T. Education Series – A Step Ahead”)]

[assembly: AssemblyCompany(“”)]

[assembly: AssemblyProduct(“A Step Ahead Series”)]

[assembly: AssemblyCopyright(“Copyright © A Step Ahead 2007”)]

[assembly: AssemblyTrademark(“”)]

[assembly: AssemblyCulture(“”)]

// Setting ComVisible to false makes the types in this assembly not visible

// to COM components. If you need to access a type in this assembly from

// COM, set the ComVisible attribute to true on that type.

[assembly: ComVisible(false)]

// The following GUID is for the ID of the typelib if this project is exposed to COM

[assembly: Guid(“d5389a36-3aa1-4e22-b3df-4cacd5e96531”)]

  • For above, you have to click on AssemblyInfo.cs under properties from Solution Explorer
  • The above information tells about the assembly name, title its short description

    and company who had developed it.
  • For more detail check table assembly attributes.

  • Write codes to provide the working for client application.
  • Now build solution from Build -> Build Solution or Ctrl + Shift + B
  • If build succeeded, it means you have created an assembly
  • You can check the assembly using ILDASM
