Compiler Error CS0653
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()
{
}
}
