When you create a project in Microsoft Visual Studio 2005, this attribute is automatically applied with an empty string value. You can set its value in Visual Studio 2005 by selecting the Properties for the project from the File menu, and then by clicking Assembly Information. The attribute is saved in the AssemblyInfo file in your project, and it must be removed before you can specify it in code; otherwise, you will get an error that the attribute cannot be applied multiple times.

When you right-click the assembly file in Windows Explorer, this attribute appears as the Comments value on the Version tab of the file properties dialog box.

The following code example sets the AssemblyDescriptionAttribute for a simple assembly and indicates whether or not it was defined.


using System;
using System.Reflection;

[assembly:AssemblyDescriptionAttribute("My Utility")]
public class Test {

    public static void Main() 
    {
        //  Get the assembly.
        Assembly asm = Assembly.GetCallingAssembly();

        //  Verify that the description is applied.
        Type aType = typeof(AssemblyDescriptionAttribute);
        Console.WriteLine("Description applied: {0}", 
            asm.IsDefined(aType, false));
    }
}
//  The output is:
//  Description Applied: True
