Compiler Error CS0653 

Error Message

Cannot apply attribute class 'class' because it is abstract

An abstract custom attribute class cannot be used as an attribute.

The following sample generates CS0653:

// CS0653.cs
using System;

public abstract class MyAttribute : Attribute
{
}

public class My2Attribute : MyAttribute
{
}

[My]   // CS0653
// try the following line instead
// [My2]
class MyClass
{
   public static void Main()
   {
   }
}
